Abstract  Molten metal meniscus profile and mold flux channel width are measured under high frequency magnetic field with different intensities by model experiments, then the dynamic pressure in mold flux channel is calculated during one mold oscillation period. It is found that the high frequency magnetic field can decrease the dynamic pressure greatly, which may be one possible mechanism of improving the billets surface quality by soft-contact mold electromagnetic continuous casting. According to the calculation, the mold flux channel dynamic pressure can not be decreased unlimitedly by increasing magnetic flux density, there must be a most appropriate magnetic flux density in order to get best billet surface quality.
Key words:  electromagnetic continuous casting      mold flux channel      dynamic pressure
