Abstract:
Apparatus and method are provided for electric induction heating and/or stirring of a molten electrically conductive composition in a containment vessel with the apparatus being removably insertable in the molten composition. An induction coil embedded in refractory or a coating is submerged in the composition and used to heat and/or stir the molten composition either externally or internally to the refractory or coating.
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.
