Regular Power Graphite Electrode
Regular Power Graphite Electrodes are manufactured with high quality raw materials, including the petroleum cokes produced in Fushun NO.2 Petroleum Factory and the coal tar pitch produced in Anshan,through the process of calcining,dosing,kneading,extruding,baking, graphitizing, machining etc. And nipples are manufactured with the technology of triplicate impregnation and quadruple baking.
