PROBLEM TO BE SOLVED: To provide a graphitization furnace which enables to uniformize and improve quality. SOLUTION: In a continuous type graphitization furnace, raw material powders P charged from a top of the furnace 10, are graphitized with heat through current supply between electrodes 12 and 13 installed inside of the furnace 10. The graphite powders Q are collected at a bottom of the furnace 10. The furnace 10 is equipped with a main collection route 20 and sub-collection routes 30. In the main collection route 20, a main intake 21 intaking graphite powders Q, is placed underneath the center of the heat graphtization zone, and a main channel 22 is placed to connect the main intake 21 to the outside of the furnace 10. In the sub-collection routes 30, sub-intakes 31 intaking graphite powders Q, are placed around the main intake 21, and sub-channels 32 are placed to connect the sub-intake 31 to the outside of the furnace 10. |
