Based on the Maxwell's equations and low‐Reynolds number k−ϵ turbulence model, a coupled three‐dimensional numerical model has been developed to describe the electromagnetic field, fluid flow, and solidification in a bloom continuous casting mold with electromagnetic stirring (M‐EMS). The optimum frequency is obtained by calculating the maximum electromagnetic torque of the strand with consideration of mold tube shield effect. The effect of stirring current intensity on the turbulent flow, temperature distribution, and shell growth has been investigated numerically. According to the simulation results, the electromagnetic force with a circumferential distribution on the strand transverse section, and a swirling flow field along the axial direction of the strand are observed in the mold region with the application of M‐EMS. It is shown that the melt maximum swirling flow velocity decreases from 0.420 to 0.226 m s−1 and the flow field changes remarkably when solidification is involved in the model. With the current intensity increasing from 260 to 500 A, the swirling flow intensifies significantly, which prevents the superheated molten steel moving downwards to the liquid core and promotes the superheat dissipation in mold.
