操業の確立が肝要である。In recent years, development of a manufacturing technique for directly processing a molten metal (including an alloy; the same applies hereinafter) to a metal ribbon by a liquid quenching method such as a single roll method or a twin roll method has been advanced. The first of the important elemental technologies in these direct plate-making technologies is the plate-making technology itself relating to the uniformity of the plate thickness and surface properties, etc., but considering industrial production, stable operation is equivalent to that. Establishment is essential.

た。In most cases, the single roll method is used for producing a wide amorphous alloy ribbon which can be applied to industrial uses such as a power transformer iron core by the liquid quenching method. Many manufacturing apparatuses and manufacturing methods have been proposed so far in order to continuously and stably plate a quenched metal ribbon having excellent surface properties and plate thickness uniformity by a single roll method. That is, it goes without saying that an alloy composition having an excellent amorphous forming ability is used as a melting raw material, but the temperature and injection pressure of the molten alloy, the material and tip shape of the pouring nozzle, the gap between the nozzle and roll, the cooling roll It is known that the peripheral speed, the material of the cooling roll and the surface properties thereof are basically important manufacturing conditions for manufacturing the quenched metal ribbon.
However, even if these casting conditions are fixed,
Occasionally, the surface properties of the amorphous alloy ribbon were deteriorated, or in extreme cases, the molten metal splashed in front of or behind the nozzle, making it impossible to realize stable plate production.

ル等によって清浄化が行われてきた。When manufacturing a quenched metal ribbon by the single roll method, the cooling roll surface is a device that takes heat from the molten metal and quenches it, and is an extremely important factor that determines the surface texture of the ribbon in contact with the quenched metal ribbon. Therefore, many innovations have been made in the past to provide optimum constant conditions. For example, as proposed in Japanese Utility Model Publication No. 61-45955 and Japanese Patent Publication No. 58-35046, the cooling roll has been modified by an in-line lathe in order to adjust the surface of the cooling roll. Further, JP-A-58-25848 and JP-A-5-25848
As proposed in Japanese Laid-Open Patent Publication No. 9-130655, the surface of the cooling roll has been cleaned with a brush roll, buff roll or the like before and during the plate making operation.

Was done. That is, the surface properties of the amorphous alloy ribbon may be deteriorated, or in extreme cases, a droplet of molten metal may fly in front of or behind the nozzle, making it impossible to realize stable plate production.

Furthermore, it is to propose the condition basically required for the surface of the cooling roll.

用いる製造方法を提案する。In the present invention, by limiting the surface properties of the chill roll, even if the molten metal at high temperature comes into contact with the surface of the chill roll, so as not to cause damage to the puddle, the roll is modified by a brush roll and a buff roll. An apparatus for producing a quenched metal ribbon that does not contaminate the surface and a production method using the apparatus are proposed.

A method for producing a quenched metal ribbon, which is used as a cooling roll and wipes the surface of the cooling roll during rapid solidification of molten metal using an oil-free baffle made of a fibrous cloth.

金属の飛沫を飛散させたものと理解された。In the present invention, the reason for starting to notice the oil contamination on the surface of the cooling roll was the oil and fat adhering to the stainless steel wire used for the brush roll. The present inventors first
A quenching metal ribbon was manufactured using the manufacturing apparatus as shown in the figure, and the brush roll was rotated during the plate making to clean the surface of the cooling roll. At one time, I had the following experience. That is, until that time, clean plate making operations had been carried out, but since the brush roll was damaged, it was replaced with a new brush roll and cast, and molten metal splashed in front of or behind the pouring nozzle and became stable. I couldn't make a good plate. As a result of various investigations into the causes, the stainless steel wire of the new brush roll remained hot water during the wire processing, but since it was installed in the manufacturing equipment without noticing this, it was found on the surface of the cooling roll during the plate making operation. Came to realize that this oil had been transferred. That is, because the molten metal at high temperature was poured onto a small amount of non-uniform oil film on the surface of the chill roll, the oil was thermally decomposed and vaporized, and the volume of the oil expanded at once and the splash of molten metal was scattered. Understood

て厳しい評価を下すことができるのである。The present invention provides at least 10 amorphous alloy ribbons having a width of 100 mm or more.
It was obtained from an operation experiment in which the plate was made for more than a minute and continuously wound. In recent years, continuous plate-making of amorphous alloy ribbon is not so difficult. However, continuous plate-making and continuous winding to produce a coil-shaped amorphous alloy ribbon are not synonymous. That is, since a large amount of ribbons are produced at extremely high speed in a simple plate-making experiment, when operating for a long time, not only partial cracks formed in the amorphous alloy ribbons but also instantaneous fractures. Even its existence is never easy to determine. However, if the amorphous alloy ribbon is wound under a certain tension, it is self-evident that even if there is a momentary break or a partial crack, it is necessary to continue the winding. I can't. In other words, on the assumption of continuous winding, it is possible to make an extremely strict evaluation on the plate making situation.
本発明を得るに際して、先ず溶融金属が第１図の注湯ノ
ズル先端から流出し、冷却ロール面に衝突すると同時に
超急冷されて凝固し、急冷金属薄帯になる凝固プロセス
を冷却ロール面の付着物の観点から考察した。In obtaining the present invention, first, the molten metal flows out from the tip of the pouring nozzle of FIG. 1, collides with the cooling roll surface, and at the same time, is rapidly quenched and solidified to form a quenched metal ribbon. Considered from the viewpoint of kimono.

ど大きくないと推測される。If the melting point and boiling point of the deposit is higher than the temperature of the molten metal and remains solid even when it contacts the molten metal, it is considered that the presence of this deposit changes the heat transfer coefficient between the molten metal and the cooling roll. However, it is presumed that the effect on the solidification process is not so large.

全に破壊されるので、満足できる急冷金属薄帯は製造で
きないことにある。When considering the solidification process for a quenched metal ribbon, the most dangerous situation is that the molten metal cannot directly contact the surface of the chill roll, and thus the smooth cooling and solidification does not proceed. That is, the liquid phase or the gas phase may be present between the molten metal and the roll surface. In particular, when the inclusions are vaporized by being exposed to the high temperature of the molten metal, explosive volume expansion will occur at the interface between the molten metal and the cooling roll, so that the pool shown in FIG. Satisfactory quenched metal ribbons cannot be produced because they are destroyed.

い。In the present invention, oil was examined as such a deposit. As described above, if the surface of the chill roll was contaminated, it was not possible to manufacture a stable quenched metal ribbon. Therefore, when the possibility of causing oil contamination in the direction of the quenching roll in the apparatus for producing a quenched metal ribbon was rigorously examined, the first cause was the roll cutting operation itself. That is, generally, lathe processing of rolls is performed while applying cutting oil, but in the present invention, cutting oil is not used.
Therefore, it is preferable to use a tool made of cemented carbide, which does not cause seizure by slight heating, as the cutting tool for the copper alloy cooling roll, instead of tool steel or high speed steel. Otherwise, it will not be possible to obtain a satisfactory finished finish of the cooling roll surface.

ってはならない。Next, it was the adhesion of oil from the brush roll pressed against the surface of the cooling roll before and during plate making. This brush roll removes thin strips and oxides on the surface of the chill roll and cleans it.Stainless steel and copper alloy wires are used, but these wires often use lubricating oil. And fine line processing. Therefore, sufficient degreasing must be performed prior to plate making. Similarly, the buff roll used for cleaning the chill roll surface and for preventing fine particles from jumping into the paddle at the tip of the pouring nozzle is also pressed directly against the chill roll surface and must not contain oil.

合金薄帯８の状況も破線で示されている。The method of the present invention will be specifically described by taking the production of an amorphous alloy ribbon as an example. FIG. 1 shows that the molten metal injected from the pouring nozzle 1 is extremely rapidly cooled and solidified on the surface of the cooling roll 2 rotating at a high speed to form an amorphous alloy ribbon 3 and then is cooled from the cooling roll 2 by a gas knife 4. It shows a state of being peeled off and flying to the winder (not shown) side. Here, the refining of the cooling roll was performed using a cemented carbide tool made of WC without applying cutting oil. The brush roll 5 made of stainless steel wire having a diameter of 0.08 mm is sufficiently degreased before being installed in the manufacturing apparatus. The bafflor 6 is a clean one without oil, which is obtained by winding a gauze on a core metal a number of times.
In the figure, the situation of the amorphous alloy ribbon 8 when a pass line is formed at the position of the deflector roll 7 under tension by the winder is also indicated by a broken line.

After supplying a molten alloy of Fe 79 Mn 1 B 12 Si 7 C 1 composition (atomic%), the stopper 10 above the molten metal nozzle 1 is opened, and it is rotated at a high speed of 25 m / sec from the opening slot of the pouring nozzle 1. When the molten metal was suddenly injected onto the surface of the internal water-cooling type copper alloy cooling roll 2, the amorphous alloy ribbon 3 having a width of 100 mm was produced in close contact with the surface of the cooling roll. Then, the amorphous alloy ribbon 3 adhered to the surface of the cooling roll 2 was peeled off by the gas knife 4 by the planar high-speed air current controlled to about 3 kg / cm 2 , and was made to fly to the winder side. After capturing the flying amorphous alloy ribbon by the pinch roll 11 on the truck, the truck is moved to the rear of the winder to convey the amorphous alloy ribbon, and then at the same speed as the cooling roll. The winding was started by adhering to the winding reel of the rotating winder. The winding tension by the winder is 2-
When controlled at 4 kg / mm 2 , a stable pass line was formed and continuous plate making and winding were realized. About 20 in this state
After continuing the plate making process, while using the gas knife 4,
The pouring nozzle 1 was moved from the cooling roll 2 to stop the casting. This completes the plate making, and the thin strip at the tail end is separated from the cooling roll 2 by the gas knife 4 without flying around the cooling roll 2 and flies. Therefore, the pouring nozzle 1 was not damaged not only during plate making but also at the end of plate making. In the plate making process, a very stable pool of molten metal was formed at the tip of the pouring nozzle, and smooth casting was performed.
