MOLD FOR CONTINUOUS CASTING AND ITS PRODUCTION

摘要

PURPOSE:To improve the life in the lower part where heavy wear arises by subjecting the inside wall surface of a base body to specific ternary alloy plating as metallic plating for said wall surface. CONSTITUTION:An electronickel plating layer 2 having excellent adhesion is formed on the inside wall surface of a base body 1 of a casting mold which contacts with the molten metal to be poured therein. A ternary alloy plating layer 3 consisting of (60-98wt%) Ni, (1-20wt%) W and (1-20wt%) Fe is formed on the layer 2. A chrome plating layer 4 is further formed thereon. The layer 3 is preferably formed on the lower part of the casting mold where heavy wear arises and is formed preferably of the layer having the hardness gradient at which the hardness increases gradually from the body 1 toward the inside wall surface in contact with the molten steel.
