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.

In a furnace having an outer wall, a plurality of ceramic fiber batts compressibly stacked to form a thermally insulating inner liner, and a plurality of electrically insulating hanger members for supporting an electrical heating element within the furnace, the improvement comprising:
- anchoring means associated with the respective hanger members and placed between a pair of adjacent ceramic fiber batts for securing the respective hanger members within the furnace in a projecting relationship inwardly of the inner liner.
An electric furnace wall comprising:
- a metallic outer wall portion;
- a thermally insulating liner including a plurality of ceramic fiber batts compressibly layer stacked,
- the insulating liner being placed contiguous to the outer wall portion and forming an inner furnace wall portion;
- a plurality of electrically insulating hanger members for supporting at least one electrical heating element within the furnace;
- anchoring means associated with each hanger member, the anchoring means being placed between a pair of adjacent ceramic fiber batts for securing the hanger members in a projecting relationship inwardly and away from the inner furnace wall portion.
