Abstract: The fluctuation of the meniscus of molten steel in the mold for round billets produced by the intermediate frequency soft-contact electromagnetic continuous casting process was measured in different positions during tests with different electrical parameters and process parameters. The results showed that the meniscus fluctuates greatly under the action of IF electromagnetic field, while the center of meniscus fluctuates relatively smaller to the margin of meniscus. The whole area of meniscus fluctuates further with increasing electric power, while the fluctuation at the center of meniscus is smaller than that of the margin. It was found that the closer the level of molten steel to the center height of induction coil, the greater the fluctuation of the level, and the level is more stable in a position below the central height in comparison with the level in the similar position above the height. The fluctuation of meniscus in mold tends to be stable with increasing frequency, but its attenuation amplitude of the variance of fluctuation decreases. In an overall view, the frequency 2.5 kHz is chosen as an appropriate one.
