Production device of amorphous alloy foil and production manner of amorphous alloy foil

摘要

P To provide an apparatus for producing an amorphous alloy foil strip having a large plate thickness in an industrial scale, and to provide a method for producing the amorphous alloy foil strip. PSOLUTION: The apparatus 1 for producing the amorphous alloy foil strip S includes a cooling roll provided with a pair of cooling zones 13a and 13b via a forbidden zone 18, a drive means 11 for rotating the cooling roll, and a crucible 14 for alternately supplying molten alloy A to the outer circumferential surface of the cooling zones 13a and 13b. The crucible 14 is movable along a rail 16. While rotating and water cooling the cooling zones 13a, 13b, molten alloy is alternately supplied to the cooling zones 13a and 13b.
