Continuous casting method and continuous casting apparatus of amorphous alloy

摘要

PROBLEM TO BE SOLVED: To provide a continuous casting method and a continuous casting device for an amorphous alloy, wherein an improvement in productive efficiency of the molding of an amorphous alloy is attained.;SOLUTION: In the continuous method for an amorphous alloy, the continuous casting device 50 is used to carry out: a die heating stage where a die 1 provided with a cavity part 1b for molding at the inside is heated to a temperature higher than the melting point of the raw material alloy of an amorphous alloy; a molten metal filling stage where, in a state in which the die 1 heated by the die heating stage is arranged at a packing chamber 5 whose atmosphere is adjusted to the inert one, a molten metal 26 obtained by heating and melting the raw material alloy is filled into the cavity part 1b for molding in the die 1; a moving stage where the die 1 filled with the molten metal 26 in the molten metal filling stage is moved from the filling chamber 5 to a cooling chamber 6 separately provided from the filling chamber 5; and a cooling stage where the die 1 moved to the cooling chamber 6 by the moving stage is cooled to a temperature below the crystallization temperature of the raw material alloy in such a manner that the cooling velocity of the molten metal 26 in the die 1 holds the critical cooling velocity of the raw material alloy.;COPYRIGHT: (C)2010,JPO&INPIT
