Abstract：A coupled numerical simulation with finite element method and finite volume method was conducted based on 250 mm bloom during continuous casting with mold electromagnetic stirring. The influence of EMS current and frequency on distribution of magnetic field and flow field was studied. The comparison shows that the calculated results are basically consistent with the experimental data. On the center surface of EMS, magnetic flux density in the corner is significantly greater than that in the center. Electromagnetic force is uniform in circumferential and flow like vortex. At the same frequency, magnetic flux density, electromagnetic force and velocity all increase with the current. At the same current, in the casting direction, magnetic flux density decreases with the increase of frequency, but electromagnetic force and velocity increase with the frequency. In the radial of EMS, magnetic flux density and electromagnetic force decrease with the increase of frequency, the influence of frequency on tangential velocity is very little. For 250 mm bloom during continuous casting with mold electromagnetic stirring, the current and frequency of 480 A, 3 Hz have good stirring effect.
