ABSTRACT:
A continuous casting apparatus having a mold, a device for withdrawing the cast object from the mold object for sopporting the cast object during withdrawal, an electromagnetic agitator at a position along the path of the withdrawn cast object opposite the crater of molten metal within the cast object, and a plurality of rolls of non-magnetic material in the vicinity of the electromagnetic agitator for supporting the cast object being withdrawn from the mold. The electromagnetic agitator has a core on opposite sides of the path of the cast object having a plurality of deep slots therein facing the cast object, coils wound around the cores at the bottoms of the deep slots, and a housing of non-magnetic material over the cores on opposite sides of the path of the cast object. The housing for the cores has a head over the portions of the cores between the slots and tapering toward the path of the cast object, the housing protecting the core and the coils.
