Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a solution quenched material, and particularly the present invention relates to a method for manufacturing a solution quenched material of any one of metals, semimetals, and semiconductors.

In the present invention, the solution quenched material refers to any one of metals, semimetals, semiconductors, and ceramics having a structure consisting of at least one of amorphous and microcrystalline materials produced by the method of the present invention. shall mean.

As a method for producing an amorphous or microcrystalline ribbon, a method is known in which a molten material is jetted from a nozzle onto the rotating surface of a rotary cooling body and rapidly solidified. In this case, the rotary cooling body used is one metal rotary roll and two metal rotary rolls that rotate in contact with each other. The method using one metal rotating roll can be further divided into two methods.

The first method is usually called the one-roll method, which uses the outer peripheral surface of a rotating roll as a cooling surface and continues to eject the molten material with the nozzle fixed, resulting in continuous rapid cooling and solidification. , Usually called centrifugal quenching method, the inner circumferential surface of a rotating cylindrical drum is used as a cooling surface, and the nozzle is moved in the direction of the rotation axis while the molten metal continues to be ejected and adheres to the inner circumferential surface of the cylinder due to centrifugal force. This is a method of manufacturing a rapidly solidified thin ribbon having a relatively narrow width and helically wound around the inner circumferential surface of a cylinder by rapidly solidifying the material while it is still in the same state.

According to these methods described above, for example, Fe, Co,
The base metal is one or more elements such as Ni and Cr, and one or more elements selected from metalloids such as B, Si, C, P, Ge, etc. An alloy in which 30 atomic % is added to the base metal is melted at a temperature range of 20 to 100 °C higher than the melting point of the alloy, and the molten metal is jetted onto the rotating roll at a cooling rate of 10 ⁴ °C/sec or more. It is known that it is possible to produce a thin body of a so-called amorphous alloy, which does not have a crystalline structure and has a long-range non-periodic structure similar to that in the liquid state, by rapidly cooling the alloy.

By the way, according to the method using one rotating roll (hereinafter referred to as the single roll method) among the conventional methods, the molten material spouted onto the roll is rapidly cooled at the part that contacts the roll surface, whereas the roll The part that is not in contact with the surface, that is, the back part, is cooled slowly, and in this method, the rapidly solidified material remains attached to the roll surface for a short time and rotates with the roll, but as cooling progresses, the speed of the roll increases. Due to the centrifugal force of the rotation, the thin body is peeled off from the roll surface and blown away, so the time it takes to adhere to the roll and rotate is extremely short, and the cooling rate of the thin body to room temperature after being peeled off from the roll is essentially In general, the thin body relies solely on cooling by the atmospheric medium in which it flies, such as air or an inert gas, so that the cooling rate is generally slower than that by rolls. Furthermore, according to this method, the surface of the manufactured thin body that is in contact with the roll has a surface shape corresponding to the smoothness or unevenness of the roll surface, but the outer surface that is not in contact with the roll surface,
In other words, on the back side, after the molten metal flows down to the roll surface,
The fluid solidifies with a highly undulating surface shape, as if it were flowing freely on the roll surface. For this reason, in thin bodies manufactured by this method, the cooling rate of each layer in the thickness direction is not necessarily uniform, and therefore the structure of each layer in the thickness direction is often not uniform. It has the disadvantage that, in a cross section perpendicular to the direction, the shape of the surface in contact with the roll and the back surface are different as described above.

By the way, according to this method, the metal that has flowed down to the roll surface and solidified remains attached to the roll surface as described above and rotates with the roll for a short time, and then
Although it peels off from the roll surface, the adhesion time before peeling is not constant, and therefore the cooling effect by the rolls is not constant, so the continuous thin body produced by this method has physical and mechanical There were variations in characteristics. Moreover, according to this method, the surface precision of the thin body produced as described above is not sufficient, which is a major reason why the thin body cannot be put to practical use as an amorphous alloy material for, for example, a magnetic head or a wound iron core.

Furthermore, according to the centrifugal quenching method, which is one of the conventional methods that uses the inner peripheral surface of a rotating cylindrical drum as a cooling surface, the molten material spouted onto the inner peripheral surface of the drum is rapidly solidified and then cooled on the inner peripheral surface. Since the cylinder travels in close contact with the material, the nozzle position is moved in the direction of the rotation axis as described above in order to avoid ejecting the rapidly solidified material that is in close contact with it again. Since it is wound helically around the inner circumferential surface, this method inevitably makes it difficult to manufacture long ribbons, and the finished product has a helical, twisted shape. However, this method was not an actual industrial manufacturing method. Furthermore, this method also has the disadvantage that the shape of the surface of the ribbon in contact with the surface of the cooling body is different from that of the surface of the ribbon on the side that is not in contact with the surface of the cooling body, as in the case of the single roll method.

On the other hand, according to the conventional method using two rolls (hereinafter referred to as the double-roll method), since both the upper and lower surfaces of the thin body to be manufactured are in contact with the rolls, the surface shape of the thin body that corresponds to the shape of the surfaces of the two rolls is However, the time for the falling metal to cool down in contact with the two rolls is extremely short, which is not much different from the case with one roll, but when a thin body is cooled by two rolls, It is advantageous to use two rolls in that the material is rapidly cooled from both the upper and lower surfaces, and therefore, the structure of each layer in the thickness direction is more uniform than when a single roll method is used. However, even when using the twin roll method, as mentioned above, the time it takes for the thin body to adhere to the rolls and cool down is extremely short, so the cooling time until it reaches room temperature after being peeled off from the roll surface is caused by the atmosphere in which the thin body flies. However, the drawback that the cooling rate is generally slower than that of roll cooling has not been overcome. For this reason, the amorphous alloy material produced by this method is quenched to a different degree even by a slight change in the amount of molten metal flowing down, and when it becomes a continuous thin body, physical In addition, the disadvantage of variations in mechanical properties was unavoidable.

In addition, although it is possible to produce ribbons or clad ribbons of amorphous or microcrystalline materials using the single roll method or twin roll method, triangular, rectangular, polygonal, circular It has been impossible to make solid wires, hollow tubes, or composite wires with external cross-sectional shapes such as semicircular, elliptical, or semi-elliptical. In the case of the single roll method, it is not possible to form the shape of the free cooling surface side that is not in contact with the cooling roll into an arbitrary shape, and in the case of the twin roll method, even if grooves are formed on the roll surface, the material cannot be ejected. The cooling effect is poor due to linear contact with the surface of the cooling body.
It is not possible to obtain a good linear, tubular, composite linear or composite tubular solution quenched material.

The object of the present invention is to provide a method for producing a solution-quenched material that eliminates and improves the above-mentioned drawbacks of the solution-quenched material produced by the conventional method. A method for manufacturing a solution quenching material by jetting a molten material from a nozzle onto the surface near a contact part of a plurality of rotary cooling bodies rotating at a speed, and rapidly solidifying the material while passing through the contact part, wherein the plurality of rotary cooling bodies A cooling body cooling surface layer made of a material with good thermal conductivity that conducts heat by directly contacting the molten material, and a shaft body that transmits rotational motion to the rotary cooling body. and a deformation restoring layer made of an elastic body interposed between the cooling body cooling surface layer and the shaft body, the circumferential part has a flexible structure that is easily deformed and restored, and the circular shape of each rotary cooling body is To provide a method for producing a solution quenched material, characterized in that by selecting various shapes of the peripheral surface, the ejected material and the surface of the cooling body are brought into planar contact, thereby significantly improving the cooling effect and solidifying the material. By doing so, the above objective can be achieved.

Next, the present invention will be explained in detail.

According to the present invention, in an atmosphere of any one selected from vacuum, air, inert gas, and reducing gas, while being pressed so as to be circumscribed or inscribed with each other at a part of the circumference, A layer near the circumference of at least one cooling body of a plurality of rotary cooling bodies that rotate at a linear velocity equal to the circumferential velocity of each other and rapidly solidify the molten material jetted from the nozzle while passing through the contact portion. If it is made of a material that is easily deformed elastically, such as rubber or synthetic resin, when a normal all-metal rotary cooling body is brought into pressure contact and rotated, the ejected material and the surface of the cooling body come into contact and generate heat. The surface contact area between the ejected material and the cooling body is much larger than the contact area for conduction, and the cooling effect can be significantly improved.

Therefore, while the molten material ejected from the nozzle near the contact area of the rotary cooling body passes through a wide contact surface with the surface of the cooling body, it is easily rapidly solidified to form a smooth solution with a surface having various shapes. In the case of a molten material that can be made into a quenched material and has a component composition that easily becomes amorphous, it is possible to obtain a solution quenched material that becomes amorphous very easily. Even in the case of a molten material having the following composition, a metastable or crystalline solution quenched material can be easily produced. Furthermore, at this time, it is also possible to control the contact pressure of the rotary cooling body that is in pressure contact with each other to adjust the thickness of the solution quenched material to be produced.

Next, the principle of the present invention will be explained with reference to FIG. 1 or 2.

The circumferential portion of the rotary cooling body 1 (hereinafter referred to as a flexible rotary cooling body) in which the layer near the circumference is made of a material that easily deforms and restores its shape, and is in direct contact with the molten material. Surface layer 2 (hereinafter referred to as
The material constituting this layer (this layer is called the cooling surface layer of the cooling body) is a material that has good thermal conductivity and has enough strength and fatigue strength to withstand contact pressure and even high-speed rotation. It is necessary to use common metal materials such as copper, chromium copper, brass, beryllium copper, phosphor bronze, or other copper alloys, as well as carbon steel, stainless steel, heat-resistant steel, high-speed steel, spring steel, cold die steel,
It can be selected from among hot die steel, bearing steel, nitrided steel, borided steel, other alloy steels, Inconel-based or Incoloy-based heat-resistant alloys, taking into consideration thermal constants such as thermal conductivity and specific heat.

The lower layer 3 near the circumference (hereinafter referred to as the deformation restoration layer) is easily deformed and restored, and is contracted and deformed while passing through the rotary cooling body pressure contact part every rotation, and after passing through the same part. It can be expanded and restored to its original shape.
As shown in FIG. 1, the deformation restoration layer includes an elastic body 4 such as a general conductive belt material, a seal, etc.
Nylon rubber, polyurethane, polyester, polyamide, PVC, used as sliding materials, etc.
Polyacrylate rubber, polycarbonate, 4
Fluorinated ethylene resin, polyamide, silicone rubber, ethylene propylene rubber, chloroprene rubber, nitrile rubber, polyethylene superpolymer, etc.
Alternatively, it can be constructed using any of the above-mentioned elastic bodies reinforced with some kind of reinforcing core wire, such as steel wire or glass fiber. In addition, as shown in FIG. 2, while increasing the flexibility of the deformation restoration layer, it is also used for the purpose of eliminating vibrations when rotating in pressure contact with other rotating bodies, or for cooling the elastic body. , gases such as air, CO ₂ , N ₂ , Ar, He, and Freon gas, or liquids such as oil and water are enclosed or circulated as a medium 5 that maintains a constant pressure, while being able to rotate in pressure contact with others. It is also possible to have a structure in which it is used in combination with the elastic body component 4'.

Furthermore, in the flexible rotary cooling body, the lower side of the deformation recovery layer, that is, the portion 6 on the shaft side (hereinafter, this portion will be referred to as the shaft core) is for transmitting rotational motion, and is suitable for ordinary general machines. It can be constructed from structural metal materials. Each part of the cooling surface layer, elastic layer, and core of the cooling body must be adhered to each other with sufficient strength so that they do not peel off during rotation and become unable to transmit rotational force, or do not separate and deviate from each other. It is possible to have a structure in which the concave and convex portions are interlocked with each other.

In the present invention, among the plurality of rotary cooling bodies,
When using a rotary cooling body with a high rigidity (hereinafter referred to as a rigid rotary cooling body) other than the flexible rotary cooling body, this rigid rotary cooling body has a cooling surface layer on the cooling body. It can be constructed of the various metals, cemented carbide, graphite, boron nitride, etc., which have similar good thermal conductivity and contact pressure when used.

According to the present invention, it is possible to produce a thin ribbon-shaped solution-quenched metal material with high surface precision on both sides and high plate thickness precision, which could not be obtained by the conventional single roll method or centrifugal quench method. It is also advantageous that the drawback of constant fluctuations in the cooling distance on the roll, which is unavoidable when using the conventional single roll method, is eliminated and constant cooling conditions are always obtained.

According to the present invention, compared to the conventional twin roll method, the cooling distance from when the molten material flows down onto the rotary cooling body until it leaves the surface of the rotary cooling body can be made extremely long. In other words, according to the conventional twin roll method, the molten metal is cooled by the line contact point of the two rolls after flowing down the rolls, whereas according to the present invention, at least one of the rolls has a flexible structure. Using a pair of rotating cooling bodies with smooth circumferential surfaces, such as rotating cooling bodies, the cooling effect is significantly improved by bringing the molten material jetted from one nozzle into contact with the surface of the cooling body over a wide area. Therefore, it is possible to produce a ribbon-like solution-quenched material that has an excellent shape and is sufficiently quenched. The manufacturing method of this ribbon-like solution quenched material is Fe-Si-B system, Fe-Si-B system.

A thin ribbon can be produced from molten metal all at once.
Further, ribbons of various semiconductor materials and ceramic materials can also be produced by the method of the present invention.

Further, according to the present invention, similarly to the method of the present invention described above, a pair of rotary cooling bodies (rolls, disks, drums, etc.) each having a smooth circumferential surface, at least one of which is a flexible rotary cooling body, is used. ), two types of molten materials are jetted from two nozzles onto the surfaces of separate cooling bodies near the contact area of a pair of rotary cooling bodies, and the surface of the spouted material and the surface of the cooling body are pressed into a wide area. At the same time, the above two types of ejected materials are brought into contact with each other to significantly improve the cooling effect and quenched, and a ribbon-like solution-quenched material that is formed into a cladding material that has an excellent shape and is sufficiently quenched directly from the molten state is produced. It can be manufactured.

The method of the present invention can be applied to various amorphous and crystalline materials to produce clad ribbons with a combination of various properties, such as clad ribbons combined with corrosion-resistant materials, clad ribbons with a bimetallic effect, etc. You can also do it.

Further, according to the present invention, a circle on the circumferential surface of at least one of a plurality of rotary cooling bodies (rolls, disks, drums, etc.), at least one of which is a flexible rotary cooling body, is provided. A groove-like recess with a width of about 0.03 to 1.0 mm having a cross-sectional shape of a triangle, rectangle, polygon, semicircle, or semi-ellipse is provided in the circumferential direction, and a groove-like recess is provided in each of the plurality of rotary cooling bodies. In some cases, the groove-shaped recesses are made to correspond to each other and combined into a groove shape, and when a molten material is ejected from one nozzle into the groove-like recesses of the pressure contact parts of a plurality of rotary cooling bodies, the ejected material and the cooling body are The surface of the groove-like recess on the surface is a continuous surface such as a cylindrical surface of a groove such as a triangular prism, a quadrangular prism, a polygonal prism, a semi-cylindrical cylinder, a cylinder, a semi-elliptic cylinder, an elliptical cylinder, etc. formed in the circumferential contact part of the cooling body. Since the cooling effect can be significantly improved by bringing the materials into contact with each other, it is possible to easily produce a linear solution-quenched material, which was impossible with the conventional single roll method or twin roll method.

By applying the method of the present invention for producing linear solution-quenched materials to various tough amorphous alloys and microcrystalline alloys, tire cord materials, reinforcing core wires for fiber-reinforced composite materials, conductive wires, etc. Metal materials that can be used in a wide range of applications such as fiber materials, filters, high gradients, magnetic filters, wire ropes, wire ropes, catalysts, superconducting wires, low thermal expansion and high strength core wires for low sag, heat-resistant power transmission cables, and conductive belt core wires. It can be produced on an industrial scale, and the method of the present invention can also be used to make continuous fibers and discontinuous fibers such as various heat-insulating and refractory materials such as ceramics and glass, and reinforcing core wires of fiber-reinforced composite materials. Therefore, the significance of the present invention is extremely large.

Further, according to the present invention, similar grooves are formed on the circumferential surface of at least one of the plurality of rotary cooling bodies, at least one of which is a flexible rotary cooling body, as in the method of the present invention. Provide a recess,
When groove-like recesses are provided in each of a plurality of rotary cooling bodies, the groove-like recesses are similarly combined to correspond to each other. The molten materials are ejected concentrically from a nozzle with a double structure, and the outer molten ejected material of the two types of molten materials and the surface of the groove-shaped recess of the cooling body are formed into a continuous plane as in the method of the present invention. Since it can be cooled by contact, a composite linear solution-quenched material can be produced. By using the method of the present invention, it is possible to manufacture a composite wire that has both the material properties of the concentric inner and outer layers directly from the molten metal in one go, so that the various examples described as examples of the use of the above-mentioned linear molten material can be made. It can also be used for a variety of other unique purposes.

Further, according to the present invention, similar to the method of the present invention described above, a similar structure is provided on the circumferential surface of at least one of the plurality of rotary coolers, at least one of which is a flexible rotary cooler. When providing a groove-like recess with a width of about 3 mm to 300 mm having a cross-sectional shape, and providing the groove-like recess in each of a plurality of rotary cooling bodies, similarly, the groove-like recesses are made to correspond to each other and are combined in a groove shape. When the molten material is ejected radially or radially from one nozzle located in the groove-like recess of the pressure contact part of the rotary cooling body toward the cooling surface of the inner wall of the groove-like recess, the molten material ejected radially Since the inner wall surface of the groove-shaped recess of the cooling body can be cooled by bringing them into continuous plane contact in the same way as in the method of the present invention, the ejected material instantly begins to form a rapidly solidified layer, and that layer As the cooling surface of the inner wall of the groove-shaped recess moves, the solidification is completed while moving, and is finally separated from the cooling surface at the separation section of the rotary cooling body and released. The tip of the nozzle used in this case is provided with a large number of linear spouting ports around the entire circumference, or a slit-shaped jetting port that goes around the entire circumference of the tip, so that the molten material can be sprayed in a radial or It can be ejected around the nozzle tip in a radial shape, such as a disk shape or a conical shape. Hollow tube-shaped solution-quenched material with excellent surface shape, uniform dimensions, and cross-sectional shapes such as triangular, rectangular, polygonal, semicircular, circular, semielliptical, and elliptical shapes close to groove shapes by the method of the present invention The present invention is of great significance because it has not been possible to produce such a hollow tubular solution quenched material using the conventional twin roll method or single roll method. By applying the method of the present invention to various tough and corrosion-resistant amorphous materials and microcrystalline alloys, pipes for chemical plants, pipes for the petroleum industry, seawater-resistant pipes, solar thermal power generation pipes, heat exchangers, etc. Its uses are extremely wide as a material for dexterous pipes or the inner or outer lining of these pipes. Furthermore, the method of the present invention can be applied to ceramics, glass, etc. to produce various heat-resistant and corrosion-resistant pipes.

In addition, for the main purpose of rapidly cooling the molten material,
It is advantageous to keep the surface temperature of the cooling body, in particular of a flexible rotary cooling body, always within a constant temperature range. In the present invention, the temperature can be controlled by irradiating the cooling surface of the flexible rotary cooling body with infrared rays or by bringing a gas or volatile liquid into contact with it, but there is a limit to its effectiveness. In addition, since the cooling surface layer of the above-mentioned rotating body cannot be cooled through the deformation recovery layer using an elastic body with poor thermal conductivity underneath, the cooling surface layer of the above-mentioned rotating body cannot be cooled through the deformation recovery layer using an elastic body with poor thermal conductivity. A metal temperature control roll made of a metal with good thermal conductivity, such as copper or silver, is provided. Some method is used from inside or outside the cooling roll, such as passing a heat exchange medium such as a gas, liquid, or volatile liquid inside the cooling roll, using a heat pipe, or spraying a gas or volatile liquid onto the outer peripheral surface. The temperature can be controlled by a method such as injecting liquid.

Furthermore, in the present invention, since the nozzle is located in a narrow space near the pressure contact portion of the rotary cooling body and ejects the molten material, the tip of the nozzle necessarily has a pointed shape. Must be. For this reason, the heat capacity of the nozzle tip is much smaller than that of the nozzle body, and the temperature tends to drop easily, so the nozzle tip often becomes clogged and the shape of the jet flow velocity tends to be uneven. In order to eliminate this drawback, according to the invention, an infrared beam or a laser beam is used to direct the ejected molten material to the nozzle tip as well as to the rotating cooling surface of the rotary cooling body. In the case of a nozzle made of a transparent material such as (such as
Alternatively, a minute puddle formed on the surface of the cooling body can be directly heated in a non-contact manner.
Furthermore, by employing the above-mentioned non-contact heating means in the present invention, the distance from the nozzle tip to the surface of the rotary cooling body can be made sufficiently long, so it is possible to make the distance from the nozzle tip to the surface of the rotary cooling body particularly large. It is advantageous when used.

In addition, in the present invention, the flexible rotary cooling body used is brought into pressure contact with a corresponding similar flexible rotary cooling body or a rigid rotary cooling body so that the rotary cooling surface layer and the deformation recovery layer in the circumferential portion are localized. Because it rotates while being deformed, the center of gravity may shift from the center of rotation, resulting in poor dynamic balance or vibrations in the circumferential portion in the radial direction. In the present invention, in addition to the other rotary cooling body that rotates in contact with the circumference of the rotating flexible structure rotary cooling body, a back-up rotary body that rotates in contact with the circumference is provided to adjust the pressurizing contact force. You can also.

Next, a manufacturing apparatus used to carry out the method of the present invention will be explained with reference to the drawings. In FIG. 3, which schematically shows a longitudinal section of one embodiment of an apparatus for carrying out the method of the apparatus of the present invention, one part of the outer peripheral surface of a metal rigid rotary cooling body 7 having a smooth circumferential surface and rotating at high speed is shown. Similarly, a flexible rotary cooling body 1 having a smooth circumferential surface is provided, which rotates in the opposite direction at the same circumferential speed while being in pressure contact with the circumferential surface. This flexible rotary cooling body 1 has a cooling body cooling surface layer 2 of about 0.5 to 5.0 mm thick made of metal with excellent thermal conductivity and strength as described above, and an elastic layer on the inside thereof. Deformation recovery layer 3 made of rich elastic material or gas or liquid
and furthermore, a diameter 30~ made of metal as described above that conducts rotational force inside it and supports load and pressure contact force.
It is constituted by a shaft core body 6 of 2000 mm. Each of the cooling layer 2, deformation recovery layer 3, and shaft core 6 has a structure that does not peel off or decompose during rotation.
The cooling layer 2 of the flexible rotary cooling body is made of a metal with excellent thermal conductivity in order to maintain an appropriate temperature, and the temperature can be controlled by passing a cooling gas or liquid inside. It is also possible to provide a roll 8, a non-contact heating means 9 such as a hot air blower or an infrared heater, or a nozzle 9' for blowing out a cooling medium such as cold air or liquid nitrogen. In addition, a back-up rotating body that comes into pressure contact may be provided in order to maintain dynamic balance during rotation. In addition, the width of the contact surface area where the rigid rotary cooling body 7 and the flexible rotary cooling body 1 come into pressure contact with each other, the pressure contact force, or the pressure contact force between the rigid rotary cooling body 7 and the flexible rotary cooling body 1 and the temperature control roll 8 can be adjusted. Alternatively, in order to adjust the contact pressure and contact area with the backup rotating body, the rotary cooling bodies 1 and 7, the temperature control roll 8, and the backup rotating body can be integrated into a housing, and each rotating body can be moved in the housing. It is also possible to have a structure like this.

Furthermore, in the apparatus shown in FIG. 5, the tip of the nozzle 18 provided at the lowest part of the container 10 is pointed for the purpose of producing a linear rapidly solidified material. The heat capacity of the part is small, and the ejection must be made close to the flexible rotary cooling rolls 16, 16' and away from the heating means 12. By providing the heating means 20, the temperature of the melt stream can finally be precisely controlled and adjusted. The molten material 11 is continuously ejected from the nozzle 18 into the groove-shaped opening formed in the part where the two flexible rotary cooling bodies 16 and 16' are in pressure contact with each other on a part of their circumferential surfaces, and is rapidly solidified. , and while the ejected material continues to pass through the grooves, its surface contacts the cooling surface of the groove of the cooling body, and the ejected material completes rapid solidification by being sandwiched between these two rotary cooling bodies. 16, 16' are released as a linear solution quenched material 21.

As the cross-sectional structure of the layer is shown in Figure 8, the dimensions of the groove-like recesses are considerably larger than the thickness of the rotary cooling body surface layer, which is 3 to 5 mm, so the interface with the deformation recovery layer has an uneven shape. It can be done.
