Abstract Electromagnetic braking has a significant effect on the flow of molten steel in the mold. In order to clarify the influence of electromagnetic force on the distribution of flow field in thin slab mold with high drawing speed, a three-dimensional mathematical model of molten steel flow in thin slab electromagnetic continuous casting mold was established. The numerical calculation method was used to study the influence of the coupling of magnetic field and flow field on the flow of molten steel. The simulation results show that the stable magnetic field produced by the five stage electromagnetic braking technology can significantly inhibit the turbulent flow of molten steel, reduce the meniscus fluctuation, and stabilize the interface of steel slag. Through the study of the relationship between high pulling speed and braking force, the matching degree between the magnetic induction intensity produced by the coil and different pulling speed is revealed.

Key words： thin slab continuous casting mold electromagnetic braking fluid flow numerical simulation
