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.
