In the continuous casting process, surface quality of steel is as important as its productivity. The surface quality is mostly decided in the molten metal flow during initial solidification stage, which progresses at the free surface of the molten steel. To improve the surface quality, this flow must be controlled. M-EMS generates the time-varying electromagnetic force, which helps to control the shape of the free surface. In this paper, we evaluate the possibility of controlling the flow at the free surface by the MHD calculations. The result showed a little possibility of the flow at the free surface being controlled. Though the free surface variation in a pulsed EMC process, which controls the shape of the free surface using the time-varying electromagnetic force component, depends on electromagnetic force, the time-varying component in the M-EMS is decided by the velocity of the molten metal. Since there is a first-order lag between the electromagnetic force and this velocity, free surface variation in M-EMS does not linearly depend on the time-varying electromagnetic component.
