摘要：
The method according to the invention relates to the continuous graphitization of prefired long carbonaceous products. It comprises the displacement of carbonaceous product in column (14) according to a horizontal displacement axis (F1), inside a furnace (12) of which the lining is a divided carbonaceous material which does not move inside the furnace (12). The column (14) is strained by jacks (21, 18) and the heating thereof is provided by Joule effect. The method is particularly applied to the manufacturing of graphite electrodes for arc furnaces in the steel making industry.
