THREE-DIMENSIONAL EDDY CURRENT ANALYSIS IN COLD CRUCIBLE USING AN INTEGRO-DIFFERENTIAL METHOD

Abstract

A current sheet approximation for eddy current distribution on the surface of the conduct- ing bodies in cold crucibles is employed, and three-dimensional eddy current distributions in the cold crucible are calculated by an integro-differential method using electric vector potential. Furthermore, power loss, Lorentz force and levitation force of the molten metal are calculated from the obtained eddy current distributions.
