Furnace for high temperature heat treatment of plastic or hardened products (17), especially heat treatment (baking/calcining) of carbon bodies which are used for cells for the electrolytic reduction of alumina or other electrometallurgical processes. The furnace consists of a first, horizontal or slightly inclining tunnel (A) in which the products (17) are being preheated, a second, substantially vertical pit or baking chamber (B), connected to said tunnel (A) in which the products (17) are subject to the high temperature heat treatment, and a third, horizontal or slightly inclining tunnel (C) in which the products are being cooled. The heat treatment of the products takes place in an inert atmosphere, and the products are transported through the furnace by means of conveyors disposed in the tunnel (A), the baking chamber (B) and the cooling tunnel (C). |
