In this paper, a mathematical model coupling electromagnetic field, flow field and temperature field using the finite element analysis software ANSYS was developed to understand the solidification at the secondary cooling zone of round billet under the application of pulse magneto-oscillation (PMO). The distribution of electromagnetic field, flow field and temperature field in the round billet was systematically studied under different electromagnetic parameters. The results showed that the intensity of magnetic field and electromagnetic force fluctuated with time and in-homogeneously distributed in space. Two flow circles formed in the upper and lower zones of bulk melt were caused by the PMO induced electromagnetic force. The numerical results about the temperature field presented that the induced flow could reduce the temperature gradient in axial direction of billet, giving rise to a more uniform internal temperature distribution.
