Graphite electrode refers to a high-temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregates and coal tar pitch as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode (referred to as graphite electrode), to distinguish it from natural graphite electrode made of natural graphite as raw material.
