ABSTRACT:
A free-standing, electric heater assembly for an electric furnace includes a heating element support structure of refractory material in the shape of an I-beam. Ceramic rods are inserted through holes in the I-beam web and cemented in place to support the electric heating element. One of the I-beam flanges serves as a base for the assembly while the second flange serves to protect the heating element from damage from falling materials in the furnace.
