    摘要: A method of controlling electromagnetic casting for carrying out the pouring of molten metal is disclosed which utilizes an electromagnetic force generated by a travelling magnetic field. The apparatus for performing the method is constructed so that a single magnet coil for generating a travelling magnetic field is employed and the input current of one phase of the three-phase alternating current to be applied to the magnet coil is subjected to phase control, whereby the electromagnetic force of the travelling magnetic field is controlled so as to automatically effect compensation for the change of the molten metal level due to the decrease of the amount of molten metal remaining to be poured.
