Abstract

PURPOSE:To obtain the molten steel suitable for continuous casting operation, of which the Al2 O3 content and the scattering of Cpi and the temperature are little, by restraining the C content at the blowing-out below 0.05pi, avoiding the excessively oxidized state and, at the same time, performing the vacuum degassing treatment and the regulation of composition in the ladle, when the Al killed steel for continuous casting is produced with the converter.
