Abstract

1494390 Continuous graphitization VEREINIGTE ALUMINIUM-WERKE AG 2 May 1975 [24 May 1974] 18518/75 Heading C1A [Also in Division H5] In a continuous process for the graphitization of baked preformed carbon bodies, the bodies that are to be graphitized are embedded in a granular, heat insulating bed of carbonaceous packing material which is contained in close-coupled continuously moving furnace cars, and in which the ends of stationary current supplying graphite electrodes projecting downwards from above are immersed for resistance heating the bodies that are to be graphitized, the electrodes being spaced apart in the direction of travel of the cars. The passage of the graphite electrodes through the packed bed is facilitated by vibrating them horizontally. The electrodes may be protected against atmospheric oxidation above the bed and up to electrode holders by high-temperature-resistant steel jackets. The carbonaceous packing material in the furnace cars may become partially graphitized and may later be used for forming the baked carbon bodies. The packing material may be a coke material (calcined anthracite, petroleum coke, pitch coke and metallurgical coke specified) or mixtures of sand and coke. Alternatively silicon carbide may be used.
