Abstract The entrainment of steel and slag interface has a great effect on casting process and the product quality. The research described the interfacial behavior between fluid steel and molten slag layer in a slab continuous casting mold with high casting speed by numerical simulation method. Good agreement between the mathematical model and experimental observation was obtained. The influences of casting speed, mold width, port angle, submergence depth of SEN and molten slag viscosity on interfacial behavior were investigated. For a given casting speed, increasing the penetration depth and downward port degree can effectively restrain interfacial oscillations. Molten slag viscosity has hardly influence on interfacial profile of steel and slag. Steel-slag interface velocity decreases with increasing molten slag viscosity.
