Abstract : A 3-D mathematical model has been developed to investigate the behavior of molten steel and liquid slag interfacial fluctuation considering the effects of vertical electromagnetic brake V-EMBr in slab continuous casting mold. The Volume of fluid VOF model is used to describe the interfacial behavior of molten steel and liquid slag with different current density of coils. The results show that the V-EMBr can effectively reduce the interfacial fluctuation caused by the changing of nozzle submergence depth and port angle For a given casting speed, as increasing of magnetic induction intensity the height of interfacial fluctuation the maximum value of wave height is significantly reduced and its position gradually approached to the narrow face of the mold, that is beneficial to reduce the possibility of mold flux entrapment.
