Abstract

See full text

A thermally insulating member for protecting water cooled pipes in the supporting structures for work pieces in heat treating furnaces comprises a cast refractory insulating member into which is solidly embedded a reticulated metal mesh reinforcement member. To provide further substantial reductions in the amount of heat loss by decreasing the thermal conductivity of the insulating member a fibrous insulating material is engaged within mesh loops of the reticulated metal structure. The fibrous insulating material has better heat insulating properties than the cast refractory material.
