Abstract: In the present study, by solving turbulent flow of molten metal and inclusion trajectory, the rising velocity of inclusion in molten steel was calculated, and the behavior of moving inclusion in the slab continuous casting mould was studied numerically. The predicted result was validated experimentally. The numerical results show that the larger the diameter of the inclusion, the greater the effect of the buoyancy, the shorter the penetration depth, the less the residence time in the mould, and the higher removal rate of the inclusion. The vertical depth of the continuous
