Description

  The present invention relates to a high heat conductive material thin plate manufacturing apparatus used for manufacturing a thin plate of a high heat conductive material such as an aluminum alloy, a magnesium alloy, or a simple substance thereof.

  Strip casting is known as one of the methods for manufacturing a thin metal plate. A twin roll type continuous casting apparatus developed as such a strip casting is arranged so that side weirs are in contact with both end surfaces in the axial direction of a pair of cooling rolls arranged in parallel in the horizontal direction. Injecting hot metal such as iron into a wedge-shaped gap formed between them and rapidly solidifying the hot water by cooling the surface of each cooling roll, and pressing the solidified metal between the roll gaps Thus, it is manufactured as a strip (thin plate) (for example, see Patent Document 1). Since this method can produce a thin metal plate directly from the raw metal hot water, the hot rolling process can be omitted and the thin plate production process can be greatly simplified. Therefore, energy saving and production cost reduction are achieved. It is known that the effect can be expected.

  However, conventionally, it is difficult to manufacture a thin plate by strip casting using metals such as aluminum alloys and magnesium alloys having a low thermal conductivity and low density compared to iron, and simple substances thereof (hereinafter referred to as high thermal conductivity materials). It had been. That is, for example, since aluminum has a low density, when aluminum alloy hot water is poured between the rolls of a twin-roll type continuous casting apparatus (strip caster) as described above, it is stored in a wedge-shaped gap between the rolls. When the meniscus of the molten metal surface vibrates, solidification occurs non-uniformly with the vibration. For this reason, the thick and thin portions are alternately formed on the continuously cast thin plate at a pitch of 20 to 30 mm in the longitudinal direction. There was a problem that it was formed.

  Therefore, for example, conventionally, when manufacturing a thin plate of an aluminum alloy, a rolling method is generally used in which a slab is once cast from aluminum alloy hot water and the slab is hot or cold rolled to obtain a thin plate. It has been implemented.

  In addition, as a technique for continuously producing the aluminum alloy plate material, a pair of horizontal cooling rolls arranged above and below can be rotated in opposite directions, and a casting nozzle is set against the roll gap of the pair of cooling rolls. Has been put into practical use by rolling aluminum alloy hot water from the horizontal direction or slightly below the horizontal direction so that casting and rolling are simultaneously performed between the pair of cooling rolls. (For example, see Patent Document 2). However, the production of aluminum alloy sheets by this rolling casting method has a mechanical production efficiency of about 1 m / min, and the production efficiency of thin iron sheets (50-80 m / min) using the twin-roll type continuous casting apparatus. Compared to this, there is a problem that it is much slower, and for this reason, it is a fact that the production of thin aluminum alloy sheets by rolling is widely performed.

  Therefore, it has been desired to improve the production efficiency by enabling continuous casting of a thin plate of a high thermal conductive material such as an aluminum alloy at a higher speed.

  Based on this idea, as shown in FIG. 3, a pair of left and right cooling rolls 1 are horizontally parallel in the same manner as the cooling rolls of the conventional twin-roll type continuous casting apparatus used for strip casting of iron or the like. In a configuration in which the flat barrel weirs 2 having fire resistance (heat resistance) are arranged on the upper side of the pair of cooling rolls 1 in the vertical direction in a configuration that is arranged and can be rotated in the opposite direction by a driving device (not shown). And the lower end of each barrel weir 2 is provided so as to be in contact with the outer peripheral surface of the corresponding cooling roll 1 along the axial direction. A side weir 3 extending vertically from a lateral position of the roll gap of the roll 1 to a position corresponding to the upper end portion of each barrel weir 2, the inner surface of the lower portion of the side weir 3 being the axial center of each cooling roll The hot water can be stored in the space surrounded by the barrel weirs 2 and the side weirs 3 by using the cooling rolls 1 so that the two roll-type aluminum alloy When strip casting is performed, aluminum alloy hot water 4 is poured into the space surrounded by the barrel weirs 2 and the side weirs 3 to maintain the level of the hot water surface at a required height position. In recent years, knowledge has been obtained that it is possible to apply the static pressure of the hot water 4 accumulated in the above-described region, thereby enabling the aluminum alloy thin plate 4a of uniform thickness to be continuously cast at a higher speed. (For example, refer nonpatent literature 1 and nonpatent literature 2).

Japanese Patent Laid-Open No. 3-128149 JP-A-9-201653 Toshio Haga, “High-speed roll casting of Al alloy”, Proceedings of the Spring Meeting of Plastic Processing in 2002, Japan Society for Technology of Plasticity, May 2002, p. 283-284 Toshio Haga and three others, “Preparation and Properties of Al Alloy Sheets Using the Atypical Twin Roll Method”, Proceedings of the Spring Meeting of Plastic Processing in 2003, Japan Society for Technology of Plasticity, May 2003, p. 247-248

  However, when each of the barrel weirs 2 and the side weirs 3 is made of a brick-like hard refractory made of boron nitride or the like that is widely used as a refractory for a furnace or the like, the hard refractory is: Since the material has some thermal conductivity, the lower end of each barrel weir 2 that contacts the cooling roll 1 and the lower portion of the side weir 3 that contacts the cooling roll 1 are heated by the transfer of cooling heat from the cooling roll 1. At the inner side surface near the lower end of the barrel weir 2 and the inner side surface at the lower part of the side weir 3, the mass of the aluminum alloy formed by the solidification of the hot water 4 is adhered. There is a risk of doing. In addition, if the mass grows and then peels off from the inner side surface of the barrel weir 2 or the side weir 3 and is caught in the roll gap of the cooling roll 1, the rotation of each cooling roll 1 is hindered. Therefore, there is a concern that continuous casting may be hindered.

  Incidentally, even in the conventional twin roll type continuous casting apparatus that performs continuous casting of iron or the like, since a side dam made of hard refractory was used, the side dam has an inner surface near the contact point with the cooling roll. However, the above-mentioned twin roll type continuous casting apparatus such as iron does not require a barrel weir, and therefore a wedge-shaped gap formed between the cooling rolls. Since the depth of hot water stored in the side weir is relatively shallow, high temperature hot water is poured inside the side weir to prevent the formation of solidified material on the inner side surface of the side weir. .

  However, when continuous casting of a high thermal conductive material such as an aluminum alloy or a magnesium alloy is performed, in order to allow the static pressure of the hot water 4 to act on the wedge-shaped gap between the cooling rolls 1, the barrel weir 2 must be used to hold the molten metal surface at a required height position, and thus prevent the occurrence of solidified material on the inner side surface of the barrel weir 2 or side weir 3 near the contact point with the cooling roll 1. For this reason, it is not possible to employ the technique of pouring hot water that is carried out when performing continuous casting of iron or the like.

  Accordingly, the present invention performs continuous casting of a thin plate of a high thermal conductive material so as to prevent the possibility that a solidified product of hot water is generated on the inner side surface of the side weir or barrel weir near the contact portion with the cooling roll. An object of the present invention is to provide an apparatus for manufacturing a thin plate with high thermal conductivity.

In order to solve the above-mentioned problems, the present invention makes contact with the outer peripheral surfaces of a pair of cooling rolls arranged in parallel in the horizontal direction so as to be rotationally driven in opposite directions over the entire length in the axial direction. A barrel weir provided with a pair of shape-retaining materials, and a side weir comprising a pair of shape-retaining materials provided so that the inner side surfaces of the lower end portions are brought into contact with both end surfaces of the cooling rolls in the axial direction. Between the pair of cooling rolls, the hot water of the high heat conductive material is stored at an upper position between the pair of cooling rolls, and the hot plate of the high heat conductive material stored between the barrel weir and the side weir is passed between the pair of cooling rolls. And the shape retaining material of each barrel weir and the surface of the shape retaining material of each side weir in contact with each cooling roll, or the shape retaining material of each barrel weir Each Refractory fibers made of a refractory fabric having a 0.1mm or more thickness for the surface of the portion in contact with the side surface and the respective cooling roll in contact with the hot water of the high thermal conductivity material of the shape-retaining material de weir obtain insulation performance It is set as the structure formed by mounting.

Further, the surface of the portion of each barrel weir and the shape retaining material of each side weir that is in contact with each cooling roll, or the shape retaining material of each barrel weir and the shape retaining member of each side weir A fireproof cloth having a thickness of 0.1 mm or more that is attached to the surface on the side in contact with the hot water and the surface of the portion in contact with each cooling roll to constitute the barrel weir and the side weir is formed with a length of 0.1 mm or more on the surface portion. It is set as the structure made into the carpet-like thing which equips with a fireproof fiber so that it may raise.

Furthermore, the surface of the portion of the shape retaining material of each barrel weir and the shape retaining material of each side weir that is in contact with each cooling roll, or the heat retaining material of the shape retaining material of each barrel weir and the shape retaining material of each side weir. A fireproof cloth having a thickness of 0.1 mm or more and a woven fabric of fireproof fiber of 0.1 mm or more is attached to the surface of the side in contact with the hot water and the surface of the part in contact with each cooling roll to constitute the barrel weir and the side weir . It is set as the structure formed by laminating | stacking so that it may become thickness.

Furthermore, the surface of the portion of the shape retaining material of each barrel weir and the shape retaining material of each side weir that is in contact with each cooling roll, or the heat retaining material of the shape retaining material of each barrel weir and the shape retaining material of each side weir. Do you entangle the refractory fiber three-dimensionally with a refractory cloth with a thickness of 0.1 mm or more that is attached to the surface of the side that contacts the hot water and the surface of the part that contacts each cooling roll to form the barrel weir and side weir? Or it is set as the structure made into the three-dimensional textile fabric which weaves.

Furthermore, it is set as the structure which attached to each shape holding material of the fireproof cloth as a structural member of each barrel dam and each side dam with adhesion | attachment or mechanical mounting | wearing.

According to the apparatus for producing a high thermal conductive material thin plate of the present invention, the following excellent effects are exhibited.
(1) A pair of shape holders provided in such a manner that the lower ends thereof are brought into contact with the outer peripheral surfaces of a pair of cooling rolls arranged in parallel with each other in the horizontal direction so as to be rotationally driven in opposite directions over the entire length in the axial direction. The pair of cooling between the barrel weir provided with the material and the side weir provided with the pair of shape holding materials provided so that the inner side surfaces of the lower end portions are brought into contact with both end surfaces in the axial direction of the respective cooling rolls. The high heat conductive material hot water is stored at an upper position between the rolls, and the thin plate can be continuously cast by passing the hot heat conductive material hot water stored between the barrel weir and the side weir between the pair of cooling rolls. And the shape retaining material of each barrel weir and the surface of the shape retaining material of each side weir in contact with each cooling roll, or the shape retaining material of each barrel weir and the shape retaining material of each side weir. High heat transfer Because as obtained by mounting arrangement refractory fibers made of a refractory fabric having a 0.1mm or more thickness for the surface of the side in contact with the hot water timber and the surface of the portion in contact with the respective cooling roll to obtain a heat insulating performance, a barrel High thermal insulation performance can be obtained by the air layer present in the gaps of the refractory fibers constituting the refractory cloth on the surface of the portion of the dam and the side dam that contacts the cooling roll. Moreover, the high heat insulation performance by the layer of the air which exists between the refractory fibers of the said refractory cloth can be obtained also on the surface of the part in contact with the hot water of the high thermal conductive material of the barrel dam and the side dam. For this reason, it is possible to prevent the transition of cold heat from the cooling rolls to the barrel weir and the side weir, and also to prevent the heat transition between the barrel weir and the side weir and the hot water of the high heat conductive material. It is possible to prevent the occurrence of the solidified product of the hot water of the high thermal conductive material in the vicinity of the contact portion with the cooling roll in the weir and the side weir. Therefore, it is possible to eliminate the possibility that the solidified material is peeled off from the surface of the barrel weir or the side weir and is caught in the roll gap of the cooling roll, and the continuous casting of the thin plate of the high heat conductive material can be performed stably.
(2) Even if the fireproof fibers exposed on the surface of the barrel weir and the side weir are worn by sliding with the rotating cooling roll, the fireproof cloth has a thickness of 0.1 mm or more . Therefore, it is possible to prevent deterioration of the heat insulation performance over a long period of time due to the air layer existing between the remaining refractory fibers. Therefore, the heat insulation between the barrel weir and side weir and the cooling roll is not impaired for a long time.
(3) Further, since when the thickness of the refractory cloth or more 0.5mm a refractory cloth can be provided with excellent heat insulating property, complete response insulation performance in refractory cloth mounting surface of the barrel weir and the side weirs Can be shown.
(4) In the above configuration, the surface of the portion of the shape retaining material of each barrel weir and the shape retaining material of each side weir that is in contact with each cooling roll, or the shape retaining material of each barrel weir and the shape retaining material of each side weir A fireproof cloth having a thickness of 0.1 mm or more that is attached to the surface of the high thermal conductive material in contact with hot water and the surface of the portion in contact with each cooling roll to constitute a barrel weir and a side weir, 0.1 mm on the surface portion By adopting a carpet-like configuration in which the refractory fibers are densely provided so as to be raised to the above length, the wear of the refractory cloth caused by contact with the rotating cooling roll is caused by the raised refractory fibers. Since it acts so as to shorten the length dimension, it is possible to prevent the influence of the strength in the surface direction of the refractory cloth from being affected, and the density of the refractory fibers arranged per unit area does not change. Obtained by There heat insulating performance can be maintained over a long period of time.
(5) In the above configuration, the shape retaining material of each barrel weir and the surface of the shape retaining material of each side weir in contact with each cooling roll, or the shape retaining material of each barrel weir and the shape retaining material of each side weir A fireproof cloth having a thickness of 0.1 mm or more which is attached to the surface of the high thermal conductive material in contact with hot water and the surface of the portion in contact with each cooling roll to form a barrel weir and a side weir, and a woven fabric of fireproof fiber 0 Even if the refractory fiber exposed on the surface wears out and a hole is opened in the fabric layer containing the refractory fiber, the structure is formed by laminating to a thickness of 1 mm or more. The high heat insulation performance obtained by said (1) can be hold | maintained by the layer of the air which exists between the fireproof fibers which form the layer of the textile fabric located in the downward direction.
(6) The surface of the part of the shape retaining material of each barrel weir and the shape retaining material of each side weir in contact with each cooling roll, or the shape retaining material of each of the barrel weirs and the high heat conductive material of the shape retaining material of each side weir Do you entangle the refractory fiber three-dimensionally with a refractory cloth with a thickness of 0.1 mm or more that is attached to the surface of the side that contacts the hot water and the surface of the part that contacts each cooling roll to form the barrel weir and side weir? Or, by adopting a woven three-dimensional woven structure, even if the refractory fiber exposed on the surface is worn, the three-dimensional entanglement of the refractory fiber in the unworn part or the influence on the woven structure is reduced. Since it can suppress, the intensity | strength of a fireproof cloth can be raised and the high heat insulation performance obtained by said (1) can be maintained over a long term.
(7) Each barrel weir and each side weir is configured by attaching the fireproof cloth as a constituent member of each barrel weir and each side weir to each shape retaining material by bonding or mechanical attachment. It is possible to easily attach the fireproof cloth to the surface portion of the weir.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 (a), (b), and (c) show an embodiment of a high thermal conductive material thin plate manufacturing apparatus of the present invention, and a pair of high thermal conductive material thin plate manufacturing apparatuses having the same configuration as shown in FIG. As a barrel weir, the surface part of the lower end in contact with the cooling roll 1 of the metal plate 5 as a shape holding member for holding a flat plate shape, or the inner side in contact with the hot water 4 stored at an upper position between the pair of cooling rolls 1 A barrel weir 2a having a structure in which a fireproof cloth 6 having a required thickness is attached to the surface portion of the slab is used, and as a pair of side dams, a shape is maintained to hold a flat plate shape. On the inner surface of the portion of the metal plate 7 as a member that is in contact with both axial end surfaces of the pair of cooling rolls 1 or on the surface of the portion that is in contact with the hot water 4 stored at an upper position between the pair of cooling rolls 1 Have the required thickness Unishi be to use a side weir 3a of the mounting formed by constituting the refractory cloth 6 are.

  The fireproof cloth 6 as a constituent member of each of the barrel weirs 2a and the side weirs 3a has a carpet-like structure in which the fireproof fibers 8 are densely raised so as to extend on the surface side to a required length, for example, about 10 to 20 mm. It is as. The carpet-like structure referred to here indicates an arrangement state of each refractory fiber 8 on the surface side of the refractory cloth 6, and defines how the refractory fibers 8 are put together on the back side of the refractory cloth 6. Not what you want. Accordingly, as shown in FIGS. 1B and 1C, each refractory fiber 8 is folded in two and has a structure other than exposing both ends of the refractory fiber 8 on the surface side of the refractory cloth 6, for example, straight in the front and back direction of the refractory cloth 6. It is good also as the structure which has arranged the shape of the refractory fiber 8, and how to put together each refractory fiber 8 in the back surface side of the refractory cloth 6 knits the refractory fibers 8, entangles the refractory fibers 8, and the required heat resistance Any method may be employed, such as embedding the refractory fiber 8 in a base material having the property and fixing with an adhesive having a required heat resistance.

  The fireproof fiber 8 only needs to have a high temperature resistance that can withstand the temperature of the hot water 4 of the high thermal conductive material. For example, glass fiber, alumina fiber, asbestos fiber, and the like are generally used. It can be used as appropriate. The same applies to the following embodiments.

  In addition, the attachment of the fireproof cloth 6 to the surface part of the metal plate 5 for forming each of the barrel weirs 2a and the attachment of the fireproof cloth 6 to the surface part of the metal plate 7 for forming the respective side weirs 3a May be adhered by an adhesive having required heat resistance, or may be mechanically attached using a fixture such as a bracket (not shown).

  When manufacturing a thin plate of a high heat conductive material using the high heat conductive material thin plate manufacturing apparatus of the present invention, each of the cooling rolls is rotated in a direction in which the cooling rolls 1 face each other by a driving device (not shown). For example, an aluminum alloy hot water 4 is injected as hot water of a high thermal conductivity material into the space surrounded by the barrel weirs 2a and the side weirs 3a above the wedge-shaped gaps between the two. At this time, if the surface of the hot water 4 stored in the space surrounded by the barrel weirs 2a and the side weirs 3a is maintained at a required height level, the static pressure of the stored hot water 4 acts. Under the given conditions, the aluminum alloy hot water 4 is cooled and solidified on the surface portion of each cooling roll 1, and is crimped between the two cooling rolls 1, on which the solidified product rotates, to form aluminum. The alloy thin plate 4a is continuously formed.

  The barrel weir 2a and the side weir 3a in the high thermal conductive material thin plate manufacturing apparatus according to the present invention have a configuration in which the surface portion of the portion in contact with the cooling roll 1 is covered with the fireproof cloth 6 as described above. In addition, since air is contained between the refractory fibers 8 and high heat insulation performance can be exhibited by the presence of the layer of air, the barrel weirs 2a and the side weirs are transferred by the transfer of cold heat from the cooling roll 1. It is prevented that the temperature of 3a falls. Moreover, since the inner side surface part which contacts the hot water 4 in each said barrel dam 2a and the side dam 3a is also covered with the fireproof cloth 6 which has the said high heat insulation performance, it contacts with each said barrel dam 2a and the side dam 3a. The transfer of heat with hot water 4 is prevented. Therefore, the aluminum alloy hot water 4 is solidified at a location in the vicinity of the contact portion between each barrel weir 2a and the side weir 3a with the cooling roll 1, that is, the lower end portion of the barrel weir 2a and the inner side surface portion of the lower portion of the side weir 3a. This is prevented in advance.

  As a result, it is possible to eliminate the possibility that the solidified material that has grown on the surface portions of the respective weirs 2a and 3a is peeled off and bite into the roll gap of the cooling roll 1, so that the thin plate 4a of the high heat conductive material can be removed. Continuous casting can be carried out in a stable state over a long period of time.

  Furthermore, each of the barrel weirs 2a and the side weirs 3a is gradually worn away from the surface side by the contact with the rotating cooling roll 1, but the fireproof cloth 6 Since the refractory fiber 8 is raised in the direction perpendicular to the surface, the wear caused by the contact with the cooling roll 1 is such that the length of the raised refractory fiber 8 is gradually shortened from the tip side. Act on. However, even in this case, if each weir 2a, 3a is shifted so as to be close to the corresponding cooling roll 1 by an amount corresponding to the amount of wear from the tip side of the refractory fiber 8, each barrel weir 2a, Leakage of hot water 4 from between the side weir 3a and the cooling roll 1 can be prevented. Further, even if the length of the refractory fiber 8 is shortened, a change in the density of the refractory fiber 8 arranged per unit area can be prevented, and high heat insulation performance due to the air layer existing between the refractory fibers 8 can be prevented. Since it can be maintained over a long period of time, continuous casting of the aluminum alloy thin plate 4a can be performed stably over a long period of time.

  Next, FIGS. 2 (a) and 2 (b) show another embodiment of the present invention. In the same configuration as shown in FIGS. 1 (a), (b) and (c), a barrel weir 2a and a side weir 3a is replaced with a configuration in which a carpet-like refractory cloth 6 is attached to the surface portions of the metal plates 5 and 7 for holding the shape, which are in contact with the cooling roll 1 and the hot water 4, respectively. A fireproof cloth 9 formed by laminating a woven fabric 10 made of fireproof fibers 8 to have a required thickness is attached to the surface portions in contact with the 5 and 7 cooling rolls 1 and the hot water 4.

  2A and 2B, for convenience of illustration, the fireproof cloth 9 is shown as a structure in which three layers of fabrics 10 are laminated. However, the number of layers of the fabrics 10 is not limited to three layers. However, it is determined as appropriate according to the desired thickness of the fireproof cloth and the thickness of the individual woven fabric. Other configurations are the same as those shown in FIGS. 1A, 1B and 1C, and the same components are denoted by the same reference numerals.

  According to this Embodiment, based on the layer of air contained between the individual woven fabrics 10 made of the laminated refractory fibers 8, contact with the cooling rolls 1 and hot water 4 in each barrel weir 2a and each side weir 3a Since a high heat insulating performance can be obtained at the location, the aluminum alloy hot water 4 is formed on the surface portion in the vicinity of the contact portion between the barrel weir 2a and the side weir 3a and the cooling roll 1 in the same manner as in the above embodiment. The possibility of solidifying can be prevented beforehand.

  Moreover, since the fireproof cloth 9 arranged on the surface portions of the barrel weirs 2a and the side weirs 3a has a structure in which the fabrics 10 of the fireproof fibers 8 are laminated, the fireproof fibers 8 of the fabric 10 exposed on the surface are formed. Even if the fabric 10 is worn due to friction with the rotating cooling roll 1 and a hole is opened, high heat insulation performance can be maintained by the air contained in the layer of the fabric 10 positioned on the inner side of the worn fabric 10. Therefore, according to the present embodiment, continuous casting of the aluminum alloy thin plate 4a can be performed stably over a long period of time.

  In addition, this invention is not limited only to the said embodiment, As a shape maintenance member of the barrel dam 2a and the side dam 3a, it endures the temperature transmitted from the hot water of the high heat conductive material which should be manufactured, and a shape is used. A material other than the metal plates 5 and 7 may be used as long as it can be held. As the fireproof cloths 6 and 9, the fireproof fiber 8 may be a three-dimensional woven fabric that is three-dimensionally entangled in a felt shape or three-dimensionally woven. In this case, the fireproof fiber exposed to the surface is used. Even if the fiber 8 is worn, it is possible to reduce the influence of the three-dimensional entanglement or woven structure of the refractory fiber 8 in the unworn part, so that the strength of the refractory cloths 6 and 9 can be increased. It becomes possible to maintain high heat insulation performance for a long period of time. Moreover, as long as it has the required thickness by the refractory fiber 8, the refractory cloths 6 and 9 having a fiber structure other than the structure in which the carpet and the fabric 10 are laminated may be employed. You may make it attach the fireproof cloths 6 and 9 to the whole outer surface of the metal plates 5 and 7 so that the whole surface of the barrel dam 2a and the side dam 3a may be covered. The high thermal conductive material is not limited to aluminum alloy, but can be applied to continuous casting of a single sheet of magnesium alloy, copper alloy, aluminum, magnesium, copper, and various other modifications within the scope of the present invention. Of course, it can be added.
