ABSTRACT:
Furnace for the graphitization of carbon bodies in which carbon bodies arranged in continuous row are clamped between two electrodes and heated up to the graphitization temperature by electric resistance heating. The carbon bodies are surrounded by movable shell-shaped walls and the space between the bodies and the walls contains no granular isolation materials. The furnace permits the graphitization of carbon bodies with smaller energy consumption and a shorter time.
