Abstract

PURPOSE: To obtain a steel ingot of extremely less macro segraegation such as inverted V segregation by teeming molten slag or molten steel into the apace between the outer frames and side walls provided around the side walls of a mold, and decreasing the extraction of heat of the molten steel in the mold from the side walls of the mold.
CONSTITUTION: Molten slag or molten steel, for example, molten slag 12, is teemed into the space between outer frames 10 provided around the side walls of a mold and the side walls 1. Therefore, the side walls 1 are heated from the outside, hence the extraction of heat of the molten steel 1 teemed into the mold from the side walls 1 decreases considerably.
