Abstract
PURPOSE:To prevent sectional defects and surface defects from occuring on a steel ingot by water cooling the narrow surfaces of the specific range below meniscus at the time of continuously casting a steel ingot of <=4 in ratio between broad face width and narrow face width. CONSTITUTION:At the time of producing a steel ingot of >= in ratio between broad face width and narrow face width by a continuous casting method, the continuously cast ingot narrow surfaces of a range up to 2/3.t<2>/K<2>.Vc from below the surface (meniscus) of the molten metal in the mold are water cooled within a range exceeding a fixed value in which the cooling water ratio of the broad faces is determined by kinds of steel, the thickness of the ingot, the casting speed, and the shape of an immersion nozzle for casting to the mold. [(t); ingot thickness, K; coefficient of solidification, Vc; casting speed]. The formation of the sectional defects and surface defects occuring in the pore groups at the final solidifying of the ingot may be prevented by regulating the flow of the water for cooling the narrow faces according to the flow of the water for cooling the broad faces in this way.
