Based on the distribution of magnetic field in electromagnetic horizontal continuous casting process, a two dimensional axisymmetric finite element model has been constructed. The model is meshed and implemented with the ANSYS software, and the distribution of magnetic field in continuous casting mold is obtained. The influence of frequency on magnetic flux density and lorentz force in melt is studied. Calculated results show that, with increase of frequency, magnetic flux density declines, lorentz force first increases and then declines and gradually concentrates to exterior field of melt.
