Abstract: The present invention relates to an electric channel inductor assembly. A nonremovable, hollow and nonmagnetic channel mold is used to form the one or more flow channels of the electric channel inductor assembly for electromagnetic circulation of a molten metal composition. A heated fluid medium is circulated in the hollow interior of the channel mold after the mold is situated in the inductor assembly to heat treat the refractory surrounding the exterior walls of the mold. After heat treatment a liquid is supplied to the hollow interior of the mold to chemically dissolve the channel mold prior to circulation of the molten metal composition.

Abstract: A method is provided for the detection of melt adjacent to the exterior of a bushing in an induction channel furnace. An electrically conductive mesh is disposed around the exterior surface of the bushing facing a refractory that separates the bushing from a channel in which molten metal (melt) flows. The mesh is connected to a grounded voltage source so that when an electrically conductive melt at ground potential in the channel breaches the refractory and penetrates the electrically conductive mesh an electrical circuit is completed through the melt and the grounded voltage source.
