Abstract
An induction stirring method wherein molten metal is electromagnetically stirred during continuous casting in a mold includes control of velocity of the stirring motion at the meniscus and the region adjacent to it, either to decrease or enhance the stirring of the molten metal produced by the main electromagnetic stirrer. An A.C. magnetic stirring modifier is positioned adjacent the region of meniscus to produce electromagnetic stirring of the molten metal at the meniscus, either to oppose the rotary motion of the main electromagnetic stirrer and provide a surface free from the stirring motion or to enhance the rotary stirring motion of the main magnetic stirrer. These two alternative modes of operation permit a casting machine to be used for casting molten metals requiring widely varying operating conditions.
