Effect of molten steel level on the magnetic field distribution in an electromagnetic soft-contact continuous casting mold

Three-dimensional numerical simulations on the magnetic field in an electromagnetic soft-contact continuous casting mold were carried out through the finite element software ANSYS. The effects of molten steel level in mold on the distributions of magnetic field and electromagnetic force were analyzed. The results show that the magnetic induction density, B , is mainly distributed at the profile-surface of molten steel. If the molten steel level is below the coil top, the maximum value of B is near the top surface of molten steel and falls gradually along the withdrawing direction. If the molten steel level is above the coil top, the maximum value of B is moving toward the centre of the coil as the molten steel level is rising. The distributing character of electromagnetic force is mostly consistent with that of B .
