Abstract

PURPOSE: To pregent longitudinal cracking from occuring in a steel ingot by coating a mold coating on the mold inside surface of the parts where the steel ingot parts from the mold slowly, and keeping the other parts uncoated at the time of casting molten steel to a mold made of cast iron.
CONSTITUTION: At the time of pouring molten metal into a mold 1 and producing a steel ingot as a rolling blank material, a mold coating is not applied or applied thinly on the inside surfaces of the mold corresponding to the parts vulnerable to the occurrence of corner cracking in a 100mm range on both sides from the centers of the corner parts A, B, C, D of the solidified shells 5, 8, etc. which cool faster and part faster from the inside surface of the mold. The mold coating is beforehand applied on the parts where the parting of the solidified shells of the steel ingot begins slowly, that is, the parts other than said corner parts. This decreases the occurrence of the longitudinal cracking 7 owing to the thermal stress from the other parts accompained with the early soldification and shrinkage of the corner parts, and the longitudinal cracking 9 owing to thermal stress on account of the thinness of the solidified shell 8 by the sticking of splash on the inside wall surface of the mold of the parts other than the corners.
