Abstract: A moveable graphitizing furnace to graphitize several columns of electrodes at the same time in two side by side tanks. The furnace has a metallic cage construction and a covering of firebricks arranged at sight on said cage construction and self-compensating the thermic expansion and the thrust exerted from outside on each column of electrodes to be graphitized. The furnace is further provided with screens protecting the framework and the wheels from heat, air forced cooling system to cool the bottom of the tanks, as well as water circulation cooling system to cool the bus bar electrodes also during the movement of the furnace after the graphitizing process.
