ABSTRACT:
Hanger and expansion plate structure for use with refractory brick employed in electric furnace roofs is disclosed which is designed for accommodating the variable, heat-induced expansion of such furnace bricks. The structure includes respective metallic plates having transverse, brick-engaging ribs with channels therebetween; the width of the ribs is greatest adjacent the hot face of the bricks so that the plates collapse or yield at the hot face under lateral brick expansion while remaining substantially intact adjacent the cold brick face. Thus, the variable expansion of the brick is accommodated without sacrifice of the overall integrity of the roof construction. Certain of the plates have oblique flanges which are received within complemental recesses in the bricks for supporting the latter.
