发明名称 METHOD FOR PRODUCING GRAPHITE AND PARTICULATES FOR GRAPHITE PRODUCTION
摘要 Provided are a method for producing artificial graphite through a vertical graphitization furnace with easy circulation of inert gas, uniform heating and no damage to the furnace; and particulates used therefor. The method comprises steps of: introducing graphitizable particulates having average particle diameter of 3 to 30 mm into an inside of the furnace from upper part thereof, heating the particulates at 2200° C. to 3200° C. while making inert gas flow from lower part toward upper part thereof to graphitize the particulates, and removing the graphite through lower part thereof. The particulates have average particle diameter of 3 to 30 mm and are obtained by granulating mixture comprising 100 wt parts of graphitizable carbonaceous substance powder having average particle diameter of 10 to 20 μm, 3 to 20 wt parts of binder decomposable at lower than 1000° C., and 5 to 30 wt parts of liquid which can dissolve the binder.

主权项 1. A method for producing graphite, comprising the steps of: introducing graphitizable material particulates having an average particle diameter of 3 to 30 mm into an inside of a vertical graphitization furnace from an upper part thereof, heating the graphitizable material particulates at 2200° C. to 3200° C. while making inert gas flow from a lower part toward an upper part thereof to graphitize the graphitizable material particulates, and removing obtained graphite through a lower part thereof.
