METHOD FOR MANUFACTURING HIGH-DENSITY ARTIFICIAL GRAPHITE ELECTRODE
Provided is a method for manufacturing a high-density artificial graphite electrode without substantially changing a particle size or a proportion of needle coke used, increasing an amount of binder pitch, or performing extrusion molding at a high molding pressure. The method for manufacturing a high-density artificial graphite electrode is a method for manufacturing an artificial graphite electrode by kneading binder pitch into needle coke, performing extrusion molding thereof, and then calcining and graphitizing thereof, wherein needle coke obtained by performing coke shape changing treatment for at least some of pulverized needle coke to be used, thereby increasing a ratio of an enveloping perimeter/a perimeter by 1% or more as compared with a value before the changing is used. Here, the enveloping perimeter is a length of a perimeter when apexes of convex portions of the pulverized needle coke are connected to each other via the shortest distance, and the perimeter is a length of a perimeter of a particle.
