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.

A refractory material for forming refractory components for casting metal comprising:
- at least one of colloidal alumina or colloidal silica;
- silica aggregate;
- fiber;
- and
- microbubbles,
- wherein the density of the refractory material is less than 1,200 kilograms per cubic meter.
The refractory material of claim 11, wherein the microbubbles comprise at least one half of one percent of the material by weight.
The refractory material of claim 12, wherein the colloidal silica comprises at least fifty percent of the material by weight.
The refractory material of claim 13, wherein the refractory material is formed into a transition plate for direct chill casting.
A heated refractory channel comprising:
- a working surface;
- a core adjacent to the working surface;
- a backer adjacent to the core;
- one or more heating elements disposed between the backer and the core;
- and
- insulation adjacent to the backer, wherein the core is disposed between the working surface and the backer.
-22. (canceled)
A heated refractory component comprising:
- a working surface to hold or to guide molten metal;
- a core adjacent to the working surface;
- one or more heating elements disposed within the core;
- and
- insulation, wherein the core is disposed between the working surface and the insulation.
The heated refractory component of claim 24, wherein the component comprises at least one of a spout, a thimble, a pin, a dam, a transition plate, or a channel.
