Abstract
An apparatus for melting metallic stock as a crucible in which the metallic stock is received and melted, the stock in the crucible having an axis along which the force of gravity varies, and an inductive heating system which generates an inductive heating field having an inductive power density which varies along the axis. The inductive heating field interacts with the metallic stock in the crucible so that the radiation energy generated by the inductive heating field counteracts the hydrostatic pressure of the melt in the crucible.
