Claims

[Claims for Utility Model Registration] (1) A heating element that holds electric resistance heating elements spirally arranged along the inner peripheral surface of a furnace wall formed in the shape of a vertical hollow cylinder at a predetermined pitch. The holder includes a holder body formed from a heat-resistant block having a substantially rectangular cross section and fitted into a vertical groove provided on the inner circumferential surface of the furnace wall, and a holder body that protrudes from the holder body and generates electric resistance. The holder body has a convex part provided on the upper or lower surface thereof, and a convex part provided on the upper or lower surface of another adjacent holder body. A heating element holder characterized by having a recess that can be fitted vertically to the heating element holder. (2) Claim (1), wherein the heating element holding part has a vertically enlarged tip, and the recess for supporting the electrical resistance heating element is formed between the tip and the holder body.
The heating element holder described in . (3) The holder body is equipped with a through hole, and a plurality of heating element holders are stacked vertically in the vertical groove provided on the inner peripheral surface of the furnace wall, and a long and thin reinforcing member is inserted into the through hole of the holder body. The heating element holder according to claim 1, wherein when the heating element holder is inserted through the heating element holder, the plurality of vertically adjacent heating element holders are more stably fixed.
