ABSTRACT OF THE DISCLOSURE A furnace water cooled tube wall portion (10) is separated from heated gasses by cast refractory material (12). A metal isolation plate (14) against the tubes (18) separates the tubes from the refractory material (12) and has projecting elongated anchors (30) with shanks (32) attached at spaced locations to mechanically join the refractory material to isola- tion plate (14). Anchors (30) have conical chamber washers welded to shanks (32) to shield the locations from cast refrac- tory material at the spaced locations. This permits bending of shanks (32) to accommodate thermal expansion force created movement between isolation plate (14) and the refractory material (12).
