High Power Graphite Electrodes are manufactured with the high quality raw materials, including the petroleum cokes produced in Fushun No. 2 Petroleum Factory,the coal tar pitch produced in Anshan and 30% needle pitch cokes imported from Japan,according to the HP electrode productive technology. The production processes are including calcining, dosing, kneading, extruding, baking, high impregnation, rebaking, graphitizing, machining etc. And electrodes are matched with UHP nipples, manufactured with 100% needle pitch cokes imported from Japan, according to the technology of triplicate impregnation and quadruple baking.
