Abstract Based on the numerical simulation, a round softcontact mold with diameter 100 mm was designed. Using molten PbSnBi lowmelting alloy, the meniscus behavior in the round billet continuous caster with high frequency magnetic field was investigated. The effects of some parameters, such as frequency, electric power and metal level, on the meniscus deformation were discussed. The 0.22%(wt) C carbon steel was successfully casted in the pilot continuous casting machine. The results show that on the azimuthal direction the magnetic flux density distribution and meniscus deformation are relatively homogeneous when the slit number is 12. With power increasing, meniscus height increases, but the meniscus fluctuation is more intensified, the power should be controlled in an appropriate range. The reasonable power is about 5060 kW. In practice, the metal level should be controlled between the center and the top of coil. The lower the frequency, the higher the meniscus height, and the optimal frequency is about 20 kHz. The 100 mm 0.22%C carbon steel with smooth surface is obtained by applying alternative magnetic. It shows that the oscillation mark of billet surface have three different statuses, annular oscillation, smooth surface and ripple oscillation respectively.
