期待できる。(Conventional technology) In recent years, the properties required for structural and functional materials have tended to become more and more sophisticated, and compounding of materials is attracting attention as a way to increase functionality and strength. has been done. On the other hand, ribbons produced by the melt quenching method, regardless of whether they are amorphous or crystalline, are attracting attention due to their electrical, mechanical, and magnetic properties. If it becomes possible to combine ribbons of different materials, we can expect even higher functionality.

、爆発圧接法が試みられている。BACKGROUND ART Conventionally, as a method for laminating thin ribbons and compositing different materials, attempts have been made to bond them together by heating and pressurizing, a cladding method, and an explosive pressure welding method.

い。またいずれの方法も薄帯化、積層化の過程が不連続
である上、工程が複雑である。However, methods that involve a heating process often result in rearrangement of atoms, and the characteristic properties obtained by melt-quenching (eg, high strength, high toughness, corrosion resistance) are lost. Furthermore, in both methods, the process of forming thin strips and laminating them is discontinuous, and the steps are complicated.

177860, a device in which a plurality of nozzles are provided above one rotating roll in parallel with the roll surface is known, but the number of laminated layers is limited by the number of nozzles that can be installed facing the rotating roll. Ru.
また溶融金属をロール面上ではなく、直前に形成された
薄帯上に噴射することから、多層化にともない薄帯の加
熱を招く場合がある。Furthermore, since the molten metal is injected not onto the roll surface but onto the ribbon formed just before, the ribbon may be heated due to multilayering.

ル数およびロール数に制限される問題点がある。In addition, as described in Japanese Utility Model Application No. 52-126068, in the twin-roll quenching method, a nozzle is installed on the top of each roll, and the ribbon produced by each roll is passed between the rolls, pressurized, and joined. However, there is a problem that the lamination is limited by the number of nozzles and the number of rolls.

The molten metal is rapidly cooled and solidified to form a continuous ribbon, and then the ribbon is conveyed along the outer periphery of a rotating small-diameter roll so that it is inscribed in the small-diameter roll and rotates in synchronization with the circumferential speed of the small-diameter roll. After being pressed or rolled between large diameter rotating rolls,
It is characterized by continuously obtaining a quenched metal laminate by conveying it along the inner periphery of a large diameter cylindrical roll and joining it with a newly formed thin strip between a small diameter cylindrical roll and a large diameter cylindrical roll. This is a method for producing a multilayer quenched ribbon.

-Cr-P alloys and other crystalline metals include Fe-5i,
Fe-C, Al-Li, Al-Ti alloys, etc.) can be joined between small diameter and large diameter cylindrical rolls to produce a laminate with an arbitrary number of layers on the inner circumference of the large diameter cylindrical roll. That is. In addition, multiple small-diameter rolls each having a nozzle part are inscribed in the same large-diameter cylindrical roll, and dissimilar metals are ejected from each nozzle, formed into thin strips on each small-diameter roll, and joined together. It is also possible to produce a laminated ribbon of different metals on the inner circumference of the cylindrical roll.

る。Furthermore, in the present invention, it is possible to select the rapid solidification conditions that affect the properties of the ribbon, such as the rotational speed of the rolls, the shape of the nozzles, the distance between the nozzles and the rolls, etc., independently of the lamination process. In addition, the joining of the ribbons takes a very short time after the surfaces are formed by melting and solidification (i.e., 17 n minutes if the rotational speed of the large diameter cylindrical roll is n r, p, m).
Therefore, good bonding can be achieved extremely easily without deteriorating bonding properties due to surface oxygen adsorption or oxidation.

以下図面を参照して本発明の方法を詳細に説明する。The method of the present invention will be explained in detail below with reference to the drawings.

れ、ノズル２の下方に小径ロール３が設けられている。In FIG. 1, a heat-resistant container 1 (for example, a quartz tube) is provided to accommodate raw metal melted by high-frequency melting or the like, and a nozzle 2 is formed at the lower end of the heat-resistant container 1. A small diameter roll 3 is provided.

内側に沿って搬送される。The large diameter cylindrical roll 4 is inscribed in the small diameter roll 3 and rotates in the same direction and synchronously with the small diameter roll. The molten metal melted in the heat-resistant container is moved through the nozzle 2 by the pressure of the inert gas.
The liquid is ejected onto the small diameter roll 3 through. The ejected molten metal contacts the small-diameter roll 3 rotating at high speed and is rapidly cooled, thereby forming the first layer 5 of the metal ribbon. Subsequently, the first layer of metal ribbon is conveyed along the small diameter roll 3,
After being pressurized or rolled between the small-diameter roll 3 and the large-diameter cylindrical roll 4 that is inscribed in the small-diameter roll and rotates, it is conveyed along the inside of the large-diameter cylindrical roll.

れる。Next, as shown in FIG. 2, when the first layer of the quenched ribbon passes between the small diameter roll 3 and the large diameter cylindrical roll 4, the second layer 6 of the ribbon is continuously produced on the small diameter roll. It is joined with. By repeating the lamination in this manner, a multilayer ribbon having an arbitrary number of layers is manufactured along the inner periphery of the large diameter cylindrical roll.

る場合がある。Note that the gap between the large-diameter cylindrical roll 4 and the small-diameter roll 3 is designed to be able to change as the ribbons are laminated. The circumferential speed inside the large-diameter cylindrical roll and the circumferential speed of the small-diameter roll must be the same, but the rotation speed N of the large-diameter cylindrical roll is N=nr/
(s+r). Here, n is the small diameter roll rotation speed, S is the small diameter roll/large diameter cylindrical roll rotation axis distance, and r is the small diameter roll radius. In addition, the pressing pressure between the large-diameter cylindrical roll and the small-diameter roll is within the elastic limit of the large-diameter cylindrical roll and the small-diameter roll, and the pressure is per unit width, taking into account the surface properties of the obtained ribbon and the bondability of the ribbon. g/r for load 1
It is necessary to set it to srm or more. Pressing at a pressure of 1 g/mm or less may result in defective joints parallel to the longitudinal direction.

In FIG. 3, heat-resistant containers (for example, quartz tubes) IA and IB are provided to respectively accommodate two types of melted raw materials A and B melted by high-frequency melting or the like, and the lower ends of these heat-resistant containers are respectively Nozzles 2A and 2B are formed.

Small diameter rolls 3A, 3B are passed through nozzles 2A, 2B.
Each is squirted on top. The ejected molten metal contacts the rolls 3A and 3B rotating at the same high speed and is rapidly cooled, thereby forming a first layer 5A of metal ribbon and a second layer 5B of B metal ribbon. Subsequently, the first layers of metal ribbons A and B are rotated along their respective small diameter rolls 3A and 3B,
After being pressed or rolled between the small diameter rolls 3A, 3B and the large diameter cylindrical roll 4, it is rotated along the large diameter cylindrical roll. The first layer of metal ribbon 5A is joined to the first layer of B metal ribbon 5B between the large diameter cylindrical roll 4 and the small diameter roll 3B. Thereafter, lamination is repeated between the small-diameter rolls 3A, 3B and the large-diameter cylindrical roll, respectively, in the same manner to produce a multilayer ribbon made of metals A and B.
