Patent ID: 8735783

Claim:
An apparatus for inductively heating and stirring an electrically conductive composition deposited in a containment vessel in a molten state, the apparatus comprising: a submersible inductor assembly comprising: at least two electrically interconnected induction coil sections, the at least two electrically interconnected induction coil sections spaced apart from each other to form a gap; a refractory surrounding at least the surfaces of the at least two electrically interconnected induction coil sections below an inductor submersion level, the refractory forming: an internal flow passage in the gap for the electrically conductive composition; an at least one inlet passage for the electrically conductive composition, the at least one inlet passage in communication with the internal flow passage; and an at least one outlet passage for the electrically conductive composition; at least one alternating current power source connected to the at least two electrically interconnected induction coil sections to electromagnetically force the electrically conductive composition by a transverse flux through the internal flow passage from the at least one inlet passage to the at least one outlet passage when the submersible inductor is submersed in the containment vessel to the inductor submersion level; and a transport apparatus for engaging the inductor assembly, the transport apparatus comprising at least a means for lowering and raising the submersible inductor assembly to the inductor submersion level.
