Abstract:
A refractory assembly for use in a roof in an ore reduction furnace is provided having a pair of refractory blocks with matchable corrugated surfaces. A corrugated plate is provided, with its corrugations having the same wavelength as and a different amplitude than the block corrugations. The plate is bound between the corrugated surfaces of the blocks so that the blocks are spaced apart by and supported on the plate. In the preferred embodiment, the corrugations are sine waves with the plate sine wave having an amplitude greater than the sine wave of the blocks. The entire assembly may be suspending as part of a furnace roof.
