ABSTRACT:
A continuous or semi-continuous metal casting method comprising the feeding of a liquid metal upon a bottom plate arranged inside an orifice of an annular inductor and the shaping of molten metal into an ingot by the electromagnetic field of said inductor. The bottom plate with the metal is then lowered, and a cooling medium is supplied upon the lateral face of the ingot in several cooling tiers arranged at various levels longitudinally of the ingot. As the bottom of the ingot comes level with a next adjacent coolant tier along the motion of the ingot cooling tier, the cooling tiers, beginning from the topmost one, are cut out or off one after the other, and until the casting ends, the cooling medium is supplied upon the lateral face of the ingot by the cooling tier that maintains the solidification front substantially at the mid-height of the inductor.
