Abstract A mathematical model was developed to study fluid flow and inclusion collision and growth in the slab continuous caster. Due to the interaction of the moving solidifying shell and the upward flow, a small corner-vortex appears near the narrow face of the mold. Such a corner-vortex leads to the peak value of inclusion’s concentration, number density and characteristic radius near the narrow face. Numerical results also showed that convective transfer of molten steel is the key factor to influence the inclusion distribution. In the upper recirculation zone, the inclusion has the annular distribution. Wall effect and inclusion’s collision and aggregation are two important factors. Under the mold, the inclusion has the “W” shape distribution in the middle plane and the “8” shape distribution in the horizontal plane. And the inclusion has the “V” shape at the narrow face and symmetry plane under the nozzle.
