Abstract

Steel sheet defects caused by inclusions are a serious quality problem. The vartical bending-type continuous casting machine is said to be more effective than the bending-type continuous casting machine for removal of inclusions, but the most effective length of the vertical section for inclusion removal has not been studied. In this paper steel sheet defects are investigated, and flow of molten steel in the mold is evaluated using the k-ε turbulence model. The most effective vertical section length for inclusion removal was found to be 2.5 to 3.0 m, irrespective of casting conditions and inclusion size.
