Abstract

PURPOSE:To prevent the production of internal defects such as porosity, etc. by disposing heat-insulating material on the inside wall of the specific casting mold and causing freezing from the bottom of the casting mold. CONSTITUTION:Heat insulating material 2 is disposed from the head to the bottom on the inside wall of a casting mold 1 of height-thickness ratio H/D; 2.2 or over. Molten steel is poured to dispose slag 3 in the upper part and electrodes 4 are positioned in the slag 3. While the molten steel 5 is being heated by supplying current to the electrodes, the molten steel is allowed to freeze 6 chiefly from the bottom. This methods prevents the production of internal defects of steel ingot and further prevents segregation, thus enabling the steel ingot of superior quality to be obtained.
