摘要

METHOD AND APPARATUS FOR PRODUCING RAPIDLY SOLIDIFIED MICROCRYSTALLINE METALLIC TAPES A method of producing a rapidly solidified microcrystalline metallic tape and an apparatus for producing the same are disclosed, wherein molten metal is continuously poured through a nozzle onto surfaces of cooling members to form a rapidly solidified metallic tape and then the tape is coiled on a reel. In this method, the metallic tape is secondarily cooled and rolled before the coiling. Further, the apparatus comprises a means for cutting out a non-steady portion of the metallic tape, a means for measuring tape thickness, a secondary cooling means, and a means for controlling a tension of the metallic tape.
