Claims8
An ingot mold for curing fused and melted material, the ingot mold comprising:
- a steel box;
- an oxide-based insulation material layer lining an inner surface of the steel box;
- a foamed carbon layer formed over the oxide-based insulation material layer;
- and
- a graphite block layer formed over the oxide-based insulation material layer,
- wherein the foamed carbon layer lines the oxide-based insulation material layer, and
- wherein the graphite block layer lines the foamed carbon layer to contact the fused and melted material, the fused and melted material being selected from the group consisting of MgO, alpha alumina, beta alumina, calcia, chromia, silica, zirconia, silicon carbide, and any combination thereof.
