Abstract

PURPOSE:To produce an amorphous film having a smooth film surface and a large area free from cracking by providing a pair of rollers which are mounted with elastic bodies on the outside circumferences of rotating bodies and further metallic sheets or foils thereon in oppositely and adjacently and introducing and passing a metal between said rollers. CONSTITUTION:Elastic materials 3 are mounted on the outside circumferences of rotating bodies 4 and further metallic sheets or foils 2 are mounted thereon. A pair of such bodies 4 are installed oppositely and adjacently to each other. Natural rubber, synthetic rubber, silicone rubber, synthetic resins, etc. are used for the bodies 4 and the thickness thereof is 0.1-50mm.. Sheets or foils of Al, Ti, Zn, Cu, Ag, Fe, etc. are used for the metallic sheets or foils. The bodies 4, 4 are rotated and a metal 1 is dropped or injected therebetween. The melt 1 past the bodies 4, 4 is formed to a film 6.

Description

[Detailed description of the invention] The present invention relates to a method for manufacturing an amorphous film.

A conventional method for producing an amorphous film is to rotate metal rollers in opposition to each other, and pour a molten material between the rollers to rapidly cool and solidify it. In this method (l), since the metal roller is used, it is a line contact, and the removal efficiency is poor.The formed film has a hard gold surface and is forcibly fed by the rotation of the probe roller, which causes unevenness on the surface of the film. The disadvantage of vines is that they tend to form cracks and cannot form a film over a large area.

The method of the present invention will be explained based on the drawings. The drawings show one embodiment of an apparatus for carrying out the method of the present invention. 1st
In the figure, l is a molten body that falls freely in the direction of the arrow! F amount is ejected. . 2 is, for example, a metal plate or foil with good thermal conductivity. This material is not limited to metal, and any material with good thermal conductivity may be used.

Examples of metals include aluminum, titanium, and zinc.

Examples include metals such as copper, silver, iron, and nickel, gold, platinum, and iron (2), and carbon plates, for example. Furthermore, the above-mentioned precious metals or alloys thereof are coated on the heat conductive plate or foil by plating, vapor deposition, sputtering, etc.
Alternatively, a chromium film may be formed 1 to increase heat resistance and chemical resistance. The melt is sent between the thermally conductive plates or foils at the outermost periphery of the rollers and held between them. 3 is a rotating shaft, ≠ is a rotating main part, and both parts are made of metal or tough plastic reinforced glass fiber, carbon fiber, etc., and the rotating shaft 3 supports the rotating main part. An elastic body j is attached to the outer periphery of the rotating main part g.

The elastic body j is made of bony natural rubber, synthetic rubber, silicone rubber, plastic, or an aggregate of these with metal fiber, carbon fiber, glass fiber, or asbestos, etc.
Its thickness is, for example, 0.1 to Sθ. This elastic body 5
Attach a heat conductive plate or foil to the outer periphery of the The 1 pairs of rollers having such a structure are made up of an elastic body S with a heat conductive plate or foil λ on the outermost periphery. Attach the crimp adjustment part≠-/ to the outer periphery of the rotating shaft 3 by screwing it. To assemble each part of the press roller, first, the elastic body 5 is inserted into the heat conductive plate or foil 2. Insert the rotating body q--2, which is divided into two parts, into this inside, and then insert the rotating body '7-j
Insert the rotating shaft 3 inside.

Screw in the crimp adjustment part from both sides of the rotating shaft 30.

The outer side of the crimping adjustment part G is inclined, and as it is screwed in, the rotating body G is expanded outward in a concentric circle from the center of the rotating shaft 3. At the same time, the elastic body 5 and the heat conductive plate or foil 2 are also pushed outward and expanded □6.

1 The rollers are in close contact with each other to form an integral roller. Goo 3 is a side slip prevention part and is an elastic body! and prevents lateral displacement when the heat conductive plate or foil rotates 20 times. Also/θ
1 is a decomposition prevention part, and this decomposition prevention part IO is attached to the outer periphery of the rotating shaft 3 by screwing.

In order to prevent the heat conduction plate or foil plate and the elastic body j from shifting laterally during rotation, the screws 9 are attached to the rotating body 2.
It is for fixing to.

When manufacturing the amorphous film 6, the motor 7 is rotated to rotate a pair of rollers through a pulley or universal joint, and the melt 1 is dropped or injected.

The molten material is inserted between the heat conductive plate or foil 2 on the outermost part of the roller (1) and cooled rapidly.

1. ′ The molten material/film passed through the 6-sea space is formed into a film.

- When the rollers are placed close to each other, the molten material that has been pushed by both rollers is sent through two heat-conducting plates or foils while being pressed by an elastic body. Coupled with the high efficiency, the produced film does not have unevenness or cracks on its surface, and it has excellent effects that allow it to easily manufacture films with a large surface area. .
