APPARATUS FOR PRODUCING AMORPHOUS ALLOY FOIL STRIP AND METHOD FOR PRODUCING AMORPHOUS ALLOY FOIL STRIP

摘要

An apparatus and a method for producing an amorphous alloy foil strip, which are capable of producing an amorphous alloy foil strip having a large sheet thickness in an industrial scale, are provided.;A production apparatus 101 for an amorphous alloy foil strip S includes: a pair of cooling rolls 113a and 113b; a driving unit 111 configured to rotate the cooling rolls; and a crucible 114 configured to supply a molten alloy sequentially to an outer circumferential surface of the cooling roll 113a and an outer circumferential surface of the cooling roll 113b. The crucible 114 is movable along a moving unit 116. A molten alloy is supplied alternately to the cooling roll 113a and the cooling roll 113b while rotating and water-cooling the cooling rolls 113a and 113b.
