Abstract
PURPOSE: To produce a steel ingot of high quality with a high yield at the time of casting the steel ingot of the short sides in the horizontal section larger than the height by causing the molten steel in the mold to freeze unidirectionally upward from the bottom and removing the thickly segregated molten steel finally remaining in the head part of the mold.
CONSTITUTION: A mold 22 is placed on a molding board 21 and a heat insulating material 27 is disposed on the inner side thereof. Molten steel 23 is injected into this mold and is allowed to freeze unidirectionally upward from the bottom. Since the heat insulating material 27 is disposed on the inner surface of the mold 22, the molten steel 23 is hardly cooled from the side face and is cooled and frozen from the bottom. Finally, the thickly segregated molten steel remained in the uppermost part of the frozen steel ingot is removed together with molten slag and heat retaining material 26 into a heat-resistant vessel 25 with an electromagnetic pump 24 just before the freezing. There are no thickly segregated portions of C, S, P, etc. in the upper part of the steel ingot, and the steel ingot of good quality may be produced with a high yield.
