Abstract
Provided herein is a system, apparatus, and method for producing refractory products, and more particularly, to producing heated refractories, passive refractories, transition plates, moldable refractories, and accessories such as heated spouts, heated pins, thimbles, and dams. A heated refractory channel as disclosed herein may include a working surface to contain molten metal within the channel; a core adjacent to the working surface; one or more heating elements disposed within the core; and insulation, where the core is disposed between the working surface and the insulation. The one or more heating elements may be molded into the core. The heating elements may be electrical resistance heating elements.
Claims11
A method for producing a heated refractory component comprising:
- casting a core of refractory material in a first mold, wherein the core produced by the first mold comprises a working surface and a back surface, wherein the core is cast with grooves defined within the back surface;
- securing at least one heating element coil into the grooves defined within the back surface;
- and
- encasing the at least one heating element coil within the grooves.
