METHOD AND DEVICE FOR MANUFACTURING METAL STRIP

To provide a method for manufacturing a metal strip not mixed with lump-shaped powder, and a device for manufacturing a metal strip used for the same.SOLUTION: A device 1 for manufacturing a metal strip comprises: a chamber 2 having a rotating cooling roll 6 installed therein; a nozzle 3 which is disposed in the chamber 2 and through which a fixed amount of molten metal M is poured to a peripheral surface 8 of the cooling roll 6; and a strip recovery path 10 communicated on one end side with the chamber 2 and having a first strip recovery part 13a for recovering a metal strip P1 generated through rapid solidification on the peripheral surface 8 of the cooling roll 6 on the other end side. The device further comprises closing means 15 which is disposed on a middle part 12 of the strip recovery path 10 and which temporarily (t1, t3) closes the strip recovery path 10, and a second strip recovery part 14 disposed below the closing means 15 and communicated with one end side of the strip recovery path 10.SELECTED DRAWING: Figure 1 【課題】塊形状粉末の混入がない金属薄帯を製造する方法と、これに用いる金属薄帯の製造装置とを提供する。【解決手段】回転する冷却ロール６を内設したチャンバ２と、該チャンバ２内に配置され、一定量の溶融金属Ｍを冷却ロール６の周面８に注湯するノズル３と、チャンバ２に一端側が連通し、且つ他端側に冷却ロール６の周面８で急冷凝固して生成された金属薄帯Ｐ１を回収する第１薄帯回収部１３ａを有する薄帯回収路１０と、を備え、該薄帯回収路１０の中間部１２に配置され、且つ該薄帯回収路１０を一的(ｔ１，ｔ３)時に閉鎖可能とする閉鎖手段１５と、該閉鎖手段１５の下方に配置され、且つ薄帯回収路１０の一端側に連通する第２薄帯回収部１４と、を有する、金属薄帯の製造装置１。【選択図】 図１
