PROBLEM TO BE SOLVED: To improve the productivity, to reduce the production cost and to make the entire part of an electric furnace compact by a graphitization production process of a continuous system. SOLUTION: This electric furnace has a furnace casing 1 in which a partial region of the inside is formed as a graphitization region 7, a raw material powder supply means 2 which is arranged to face this furnace casing 1 across the graphitization region 7, a recovering means 3 for graphite powder and at least one set of electrodes 5, 6 which are disposed at the furnace casing 1 so as to be energized to the raw material powder of the graphitization region 7. While the raw material powder fed into the furnace casing 1 from the supply means 2 passes the graphitization region 7, the raw material powder is made into the graphite powder by energization between the electrodes 5 and 6 and is taken out of the furnace casing 1 by a recovering means 3. |
