Abstract

PURPOSE: To prevent the generation of internal defects such as secondary pipes and V segregation in the axial center part of a steel ingot by setting conditions in such a way as to satisfy a specific equation in producing the steel ingot by teeming molten steel into a mold.
CONSTITUTION: In the case of casting a steel ingot, H, R, K are so set as to satisfy the specific equationIin accordance with a change in X and casting is carried out. Here, X: the thickness of the solidified phase from the side walls of the mold, H: the height of the molten steel teemed into the mold, R: the length 1/2 the inside diameter of the bottom part of the mold, K: the solidification rate ratio of the solidified phase from the molding board and the side wall side of the mold, β: (ρs-ρl)/ρl, where ρl: the density just prior to the solidification of the molten steel, ρs: the density right after the solidification of the steel.
