Abstract
A modular type heating unit or assembly having particular utility for use in a high temperature electric furnace, preferably in a group arrangement, comprises an insulating fibrous refractory block, a pair of spaced apart support rods, inner and outer support tubes and a heating element. Both the heating element and the support rods are formed of alloys to enable operation at relatively high temperatures. By utilizing this concept of modular element/insulation units, furnaces can be operated at relatively higher temperatures than is currently possible for exposed electrical element type furnaces.
