Steel sheet defect caused by inclusions is a serious quality problem. It is said that the vertical bending type CC machine has a larger effect on removal of inclusions than the bending type CC machine. But the most effective vertical length for inclusion removal in a CC machine has not been studied. In this paper, the effective vertical length for the inclusion removal is described. This study included the investigation of steel sheet defect and the development of three dimensional numerical analysis for the study of fluid flow in the continuous caster mold. The three dimensional numerical simulation technique used in this study is the k-ε turbulence model. The most effective length for inclusion removal is found to be 2.5〜3.0m, and is found to be constant for casting conditions.
