  • Method and apparatus for graphitization of carbon materials
    Patent number: 4017673
    Abstract: Continuous-type furnace for the graphitization of carbon bodies having a preheat zone, a cooling zone and a heating zone provided with an electric heating device, through which furnace the carbon bodies are cyclically transported either as a single body or in groups and are deposited between cycles on holding devices which are connected to the furnace. The motion in the direction of the length of the furnace is effected by gripping devices which reach into the furnace periodically. Graphitization of carbon bodies with considerable reduction of the energy requirements are achieved.
