Abstract
An electromagnetic stirring apparatus for stirring the liquid center core of a continuous casting. The casting is supported by and transported over guide rolls while a changing electromagnetic field is induced within the liquid casting core by induction coils positioned beneath the casting. Fingers of a stack of ferromagnetic plates form the cores of the induction coils and are positioned between the guide rolls and are close enough to the casting to induce a strong field therein.
