A model was developed for analyzing system power of electromagnetic soft-contact continuous casting system. Using finite element method

the system power and magnetic flux density distribution were calculated

and the effect of coil current and frequency on system power and magnetic flux density distribution were also discussed. The results show that as for electromagnetic soft-contact continuous casting system with partial-segment type mold

about 59%-65% of electric power is dissipated in the mold

and the maximum magnetic flux density on billet outer surface is located 5.5mm below metal free surface. The magnetic flux density is proportional to coil current

and is reduced with frequency increasing from 10 kHz to 100 kHz. The coil current has no effect on the azimuthal homogeneity of magnetic flux density

but the magnetic field is much more homogeneous while frequency is 20 kHz. The system power is proportional to the square of coil current

and the power consumption for 50 kHz is about 165% that of 20 kHz with the same magnetic flux density. For Ф178 mm electromagnetic soft-contact system

the suggested frequency is about 20 kHz.
