本発明は短時間に所望の形の金属薄板を得ることができ
る金属薄板の製造装置およびその製造方法を提供しよう
とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a thin metal plate manufacturing apparatus and a manufacturing method thereof that can obtain a metal thin plate of a desired shape in a short time.
近年溶融金属の急冷法として遠心急冷法（ドラム法）、
圧延急冷法（ソーラー法）などが開発され、これらを用
いる事により非晶質金属もしくは半非晶質金属のリボン
状シートが得られるようになった。In recent years, the centrifugal quenching method (drum method) has been used as a quenching method for molten metal.
The rolling quenching method (solar method) and other methods have been developed, and by using these methods, ribbon-shaped sheets of amorphous or semi-amorphous metals can be obtained.
しかしながら得られるリボン状シートは、作製方法上そ
の厚みに上限があり、それは約５０μｍである。However, there is an upper limit to the thickness of the obtained ribbon-like sheet due to the manufacturing method, which is about 50 μm.
従ってこれを用いて磁気ヘッド用コア、もしくは変圧器
用コア等を構成しようとする場合このリボン状シートか
ら幾枚もの相似な形をした金属薄板を切り取る工程が不
可欠である。Therefore, if this is to be used to construct a core for a magnetic head, a core for a transformer, etc., it is essential to cut out a number of similarly shaped thin metal plates from this ribbon-like sheet.
現存これらの加工工程として「打ち抜き」、「エツチン
グ」などが採用されている。These existing processing processes include "punching" and "etching".
「打ち抜き」の場合は、得られる金属薄板に機械的ひず
みが入りやすい事や、打ち抜き金型の寿命が短かいとい
う欠点があり、「エツチング」の場合には比較的時間を
用する事や工程が繁雑になる欠点がある。In the case of "punching", the drawbacks are that the resulting thin metal sheet is susceptible to mechanical strain and that the life of the punching die is short, while in the case of "etching", it is relatively time consuming and requires a long process. The disadvantage is that it becomes complicated.

金属薄板を得る事を目的とするものである。A predetermined shape is drawn on the surface of the high-speed rotating body of the present invention, and molten metal is jetted onto the surface and rapidly cooled to produce a thin metal plate with the desired shape, thereby eliminating the conventional processing steps such as those described above. The purpose of this method is to eliminate defects and obtain a thin metal plate in a desired shape in an extremely short time.
