PURPOSE:To relatively easily perform hanging work of a ceramic molding even when its length is large, to considerably improve the heat efficiency on sintering the ceramic molding and to precisely control the sintering temp. of the ceramic molding in a method by which long-length ceramic molding is hung in a sintering furnace and heating elements attached on the inner wall of the sintering furnace are caused to generate heat to sinter the molding. CONSTITUTION:Ceramic molding is held without a shielding structure in a sintering furnace. Heating elements extending along an inner wall 4a of the sintering furnace are installed. Slim structure members 11 are fixed to each heating element 10 at least on the front side. Thus, heat of the heating elements 10 is directly radiated to the ceramic molding. The structure member 11 is preferably a tubular body. It is preferable that fixing frames 9 are fitted to the inner wall and the structural members 11 are fixed to the fixing frames 9, or the structure members are directly fitted to an inner wall 4a. |
