DIE FOR CONTINUOUS CASTING AND CONTINUOUS CASTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a die for continuous casting which can reduce the frequency of rupture occurrence in drawing a solidified strand, a die production method and a continuous casting apparatus.SOLUTION: A die for continuous casting which is attached to a casting furnace and cools and molds a molten metal Y poured continuously into a rod-like slab H includes a through hole 14a through which the molten metal Y is poured. The through hole 14a is expanded in passage cross-sectional area from an inlet 14b toward an outlet 14c, and the magnification of the passage cross-sectional area per unit length increases from the inlet 14b toward the outlet 14c.
