Abstract
An electromagnetic casting apparatus wherein a ring-type inductor generates an electromagnetic field having a flux density which diminishes in intensity toward the top of the inductor to more efficiently control the shape of the molten metal within the inductor.
Claims8
In an electromagnetic apparatus for the continuous or semicontinuous casting of metal ingots or billets comprising a means to feed molten metal, a ring-type metallic electromagnetic inductor means for generating electromagnetic forces which control the shape of molten metal fed from the feeding means and disposed within the inner peripheral area of the inductor means and means for cooling the shaped molten metal surfaces to solidify the molten metal in essentially the shape imposed on the molten metal by the electromagnetic forces, the improvement comprising a ring-type metallic electromagnetic inductor provided with means for generating an electromagnetic field having a flux density which diminishes in intensity toward the top of the inductor means to control the shape of the molten metal within the inner peripheral area of the inductor means so that the vertical surface or surfaces of the molten metal are essentially straight.
