ABSTRACT:
A wall construction for an electric furnace. An outer metallic casing provides the shape and structure for the furnace and an insulating inner liner is formed of a plurality of compressibly stacked ceramic fiber batts. Electrically insulating hanger members are provided for supporting an electrical heater element within the furnace. The hanger members comprise ceramic spools mounted on elongated rods. A group of such rods are welded to a plate which is placed between a pair of adjacent batts. Means are provided for securing the plate in place for preventing movement of the hanger members. In an alternate form, the hanger members are formed, integrally with a mounting member, of ceramic.
