Abstract
A mold for use in an apparatus and process utilizing an electromagnetic field to stir a molten metal or metal alloy comprises a plurality of laminations of thermally and electrically conductive material separated by electrically insulating material. The electrically insulating material is oriented to minimize at least some of the flow path lengths of currents induced in the mold whereby magnetic induction loses caused by the mold are substantially reduced and the stirring efficiency is enhanced.
