ABSTRACT:
An insulative panel prevents heat transfer from a molten metal melt. The panel comprises a reinforced refractory slab supported along its edges. An insulation layer is placed on top of the refractory slab, thereby creating a hot zone between the molten metal and the insulation layer and a cold zone in and above the insulation layer. Reinforcing members are placed in the cold zone on top or within the insulation layer vertically above reinforcing rods in the refractory slab. Hangers extending downwardly from the reinforcing members through the insulation layer and refractory slab are joined to the reinforcing rods for supporting the reinforcing rods in the hot zone by the reinforcing or support members in the cold zone.
