Abstract：The meniscus behavior in partial-slit type round billet continuous casting mold under high frequency magnetic field was investigated using low melting alloy Sn-Pb-Bi instead of liquid steel. The effect of power, installation site of the induction coil and frequency of magnetic field on the meniscus behavior was studied on the base of meniscus shape, height and triple point position. Furthermore, model experiments with liquid steel were conducted to validate the reliability of the results obtained through the experiments using Sn-Pb-Bi. It is found that the meniscus behavior is influenced significantly by the power. The optimal installation site of the induction coil is located in the center of slit zone in the mold. The meniscus height is increased as the increase of frequency of magnetic field at the range of 20 kHz to 30 kHz. However, the rate of increase decreases when the frequency of magnetic field exceeds 30 kHz. At similar experimental circumstances, the profile of liquid steel meniscus coincides approximately with that of Sn-Pb-Bi which indicates that Sn-Pb-Bi can be used to simulate the meniscus behavior of liquid steel.
