A refractory block design for re-radiating a substantial amount of heat losses back to a heated product thereby substantially maintaining its required temperature. A relatively thin sheet of stainless steel, i.e. the ratio of the thickness of the sheet being approximately 1/500th of the thickness of the heated product, is wrapped in a sinuous manner around one side of a refractory fiber block arranged in a similar sinuous manner to tightly fit into the folds of the block for storing heat, and radiating heat back to the heated product when thermal equilibrium therebetween is reached. |
