IN-MOLD ELECTROMAGNETIC STIRRING OF MOLTEN METAL DURING CASTING

摘要

A system for electromagnetically stirring molten metal in an electrically conductive mold. An alternating electric current is applied to the walls (12) of the mold (2) and generates an electromagnetic field with the mold (21) to cause the stirring of the melt (8) therein. In one embodiment, the walls of the mold are continuous. In another, the mold wall has a non-conductive gap along the vertical length.
