ABSTRACT:
A refractory plate assembly includes a refractory plate having therethrough at least one discharge opening and a sheath tightly fitted around the periphery of the plate. The plate is formed of separate plate portions separated along planar surfaces extending outwardly from the discharge opening at positions where cracks would be formed during use of the plate if the plate were of unitary construction. The planar surfaces are separated by compressible refractory packing material, thereby forming expansion joints. The sheath compresses the packing material of the expansion joints.
