摘要
The present invention provides a method for producing an artificial graphite electrode that enables kneading and subsequent mixing to be carried out without having to increase an amount of binder pitch used even in the case of needle coke having a large pore volume. An artificial graphite electrode is produced by kneading binder pitch with needle coke, and performing extrusion molding and then performing baking and graphitization process on the same, wherein a process for kneading the binder pitch with needle coke includes at least two separate kneading stages, and the amount of binder pitch added and kneading time in these kneading stages satisfy a kneading index as represented by formula (1) below within a range of 0.1 to 0.7.; Kneading index=(a1/A)×(t1/T) (1)
