Inflatable seal for annealing furnaces – Western polyrub silicone inflatable seal for use between the cover and base of a heat treating furnace. The seal includes an annular fluid-impervious member mounted on the base. brass Valves are provided to inflate and deflate the annular member. in the inflated position, the annular member extends between the cover and the base to provide a tight seal. The casing of the member is made of a metal or any other material,
The use of bell-type annealing furnaces for heat treating coiled strips of material has become widespread in the art. These heat treating furnaces include a base of one or more pedestals on which the coiled strips of material which are to be heat treated are placed. An inner cover is placed over these coiled strips of material, and it is necessary in most instances to seal the coils within the inner cover to provide a controlled atmosphere therein.
