Abstract：According to the mold for slab caster in Steelmaking Plant of Benxi Iron and Steel Company, a physical model was established to study the effects of the gas flow rate, the immersion depth on pattern of bubble movement, surface fluctuation and slag entrapment. Then the optimization of the technological parameter was presented. The results of industrial experiment indicated that the spheric CaOAl2O3SiO2MgO inclusions, which contained the compositions of the mold powder such as Na2O and K2O, had disappeared in the surface layer of slab after the optimization. The content of nonmetallic inclusions in IF steel slab evidently reduced.
