<p>In a process of continuously graphitizing carbon bodies by electric resistance heating, the carbon bodies 1,2 move in columnar formation vertically through a graphitizing furnace surrounded by counterflow of granular carbon material 3 and are heated by an electric current flowing over electrodes 6,7 through the granular material and through the carbon bodies. The column of carbon bodies 1,2 is preheated by the granular carbon in a lower heat exchange zone III, then moves through an intermediate graphitizing zone II in which the carbon bodies 1,2 are heated by electric resistance and finally through an upper heat-exchange zone I, in which it is cooled by the granular carbon. The electrodes 6,7 may be inclined to the axis of the furnace. <IMAGE></p> |
