Abstract ABSTRACT A physical model was established to study the mechanism of molten slag behavior in slab continuous casting mould with high casting speed and argon blowing, and the effects of operation parameters on the liquid surface level oscillation and the slag entrapment were investigated. The results showed that slag entrapment was mainly caused by the turbulent large bubbles at the interface of slag and molten steel in mould with high casting speed and gas bubbling, and the vortex at the surface also was the way to cause slag entrapment, but there is no phenomenon of entrapment occurring due to high shear stress that was mentioned the main reason previously. In addition, the behavior and mechanism of typical slag entrapment were discussed, and the measures to eliminate slag entrapment were also presented.
