COMPOSITE MOLD FOR CONTINUOUSLY CASTING OF COPPER AND COPPER ALLOY, CONTINUOUS CASTING DEVICE FOR COPPER OR COPPER ALLOY, AND CONTINUOUSLY CASTING METHOD FOR COPPER OR COPPER ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a composite mold for continuously casting, continuously casting device, and continuously casting method for copper and a copper alloy, capable of obtaining an ingot of copper and the copper alloy excellent in surface quality, by suppressing the effect caused by an airgap between the ingot surface and a mold inner wall to a minimum.;SOLUTION: A mold 10 for discharging the copper and the copper alloy solidified after being supplied with a molten metal of the copper or the copper alloy, and a heat extraction assembly 20 including a catapiller 21, for rotating the side face of the ingot of the copper or the copper alloy solidified downward (casting direction) the mold 10 by the same speed as the discharging speed from the mold 10 and pushing the ingot 17, are provided.;COPYRIGHT: (C)2003,JPO
