PURPOSE:To graphitize even a high-density structure carbon baked body by charging a carbon sintered body in a cylindrical surrounding section formed with a carbonaceous material while the body is embedded in a good heat conductive packing material when many carbon baked bodies are arranged in series in an Acheson furnace in the longitudinal direction and graphitized. CONSTITUTION:Many carbon baked bodies 7 are arranged in series in the Acheson furnace in the longitudinal direction and graphitized. In this case, the carbon baked body 7 is charged in the cylindrical surrounding section 4 formed with a carbonaceous material while the body is embedded in the good heat conductive packing material 8 (e.g., graphite powder). Then the periphery is covered with an ordinary packing material 9 (e.g., coke grains) and an electric current is passed through a terminal electrode 3. The cracks and breakage of the carbon baked body generated in the process of graphitization can be effectively reduced by the soaking action of the cylindrical surrounding section 4. |
