PCT No. PCT/AU95/00074 Sec. 371 Date Nov. 14, 1996 Sec. 102(e) Date Nov. 14, 1996 PCT Filed Feb. 16, 1995 PCT Pub. No. WO95/22732 PCT Pub. Date Aug. 24, 1995A wall lining for a furnace (10) includes a refractory layer (14) having a hot face (16) exposed to the interior of the furnace. A plurality of elements of a high thermal conductivity material (18), such as copper wires or rods, extend from the outer shell (12) of the furnace into the refractory lining (14). The elements (18) provide a continuous heat conduction path to the outer shell (12) of the furnace. A cooling jacket (22) removes heat from the outer shell. The elements (18) are dispersed in the refractory lining (14) to provide a substantially uniform temperature across the hot face of the furnace in the vicinity of the elements. The wall lining may be formed by fixing an array of the elements to the inside wall of the outer shell of the furnace and applying a refractory material to the inside wall.
