ABSTRACT:
An apparatus and process for casting metals wherein the molten metal is contained and formed into a desired shape by the application of an electromagnetic field produced by a multi-turn inductor. The pitch or spacing of individual turns of the inductor is controlled to provide accurately varied electromagnetic pressure. The process includes the step of varying the distance between turns and/or the height of the individual turns to control the electromagnetic forces and balance the metallostatic pressure within the molten metal being cast.
