Abstract: The numerical prediction is conducted on the magnetic field, fluid patterns of molten steel and trajectories of inclusion particles in continuous casting mold controlled by the electromagnetic brake (EMB). The difference between maximum and minimum of shear stress on wall is used to scale the strength of jet imping on the solidified shell in the narrow face wall by molten steel discharged from the immeresd nozzle. When the EMB is applied, the flow patterns of molten steel in the mold is greatly changed, and the impingement strength of the jet is reduced. It is found that the successful control of flow pattern depends on the coil current and location of direct-current magnet.
