HP Graphite Electrodes

Graphite electrode are manufactured with high quality raw materials including
petroleum cokes, needle cokes and coal tar pitch through the production
processes of calcining, crushing, screening, dosing, kneading, extruding,
baking, impregnation, graphitization, machining. Our products products are
characterized by superior compact structure, good electrical and thermal
conductivity, high mechanical strength and high resistance to oxidation and
corrosion in high tempertature. The graphite electrode are widely used in
electric arc furnace and ladle refining furnaces foe steel making and used in
ore smelting furnace for producing industrial silicocn, yellow phosphorus,
corundum, nonmetals and so on, it is one essential part of the raw material
industry.
