High Density Graphite Electrodes

High Density Graphite electrodes are manufactured with the high quality raw materials, including the petroleum cokes produced in Fushun No.2 Petroleum Factory
and the coal tar pitch produced in Anshan,according to the same productive technology as HP electrodes. The production processes are including calcining, dosing,kneading, extruding, baking, high impregnation, rebaking, graphitizing, machining etc. And electrodes are matched with HP nipples, manufactured with 80% needle pitch cokes imported from Japan, according to the technology of triplicate impregnation and quadruple baking.
