Abstract
Metal material is melted by moving the magnetic flux of electromagnets virtually perpendicular to an arc column to apply Lorentz force to the arc column and the metal material so that the arc column can move over the metal material surface. The movement direction and speed of the arc column are determined by detecting the arc voltage of the arc column. Feed back control is performed by comparing the obtained detection data with preset data so that optimum control is performed, and the molten metal is poured into a casting mold.
