Abstract: FEM is used to simulate numerically the magnetic flux density and induced current distribution in a rectangular soft-contact electromagnetic continuous casting (EMCC) mold. Investigates the influences of such parameters as power frequency, electric conductivity of mold material and mold construction on the magnetic flux density and induced current, as well as the effect of induced current on the magnetic flux density in the mold. The simulative results show that the magnetic flux density due to induced current formed on mold segment affects greatly the magnetic flux density in mold, and utilizing reasonably the induced current can enhance the magnetic flux density in mold so as to save energy. For slit mold, within a certain frequency band, the magnetic flux density due to induced current can enhance the magnetic flux density in mold, but, if the frequency is beyond the band, the enhancement is not obvious. In the high-frequency EMCC process, the magnetic flux density in mold mainly comes out of the penetration of magnetic flux density due to the induction of outer coil, while in case of low frequency how to utilize fully the induced or secondary field to enhance the magnetic field in mold should be taken into account.
