Classification and application of graphite electrodes

Graphite electrode is made of high quality calcined petroleum coke and imported needle petroleum coke. It is manufactured through the process of calcining, dosing, mixing, forming, baking, impregnating, graphitization in a high temperature of over 3000°c, and then machining.
Graphite electrode has the advantages of low electrical resistance, low ash content, high mechanical strength, high resistance for abrupt change of temperature and high-yield in melting process.

Widely used in Electric Arc Furnace, Ladle Furnace, Mineral-heated Furnace for steel-making and other metallic or non-metallic materials, such as silicon, phosphorus, etc.

RP, HP, SHP, UHP grade

150mm, 200mm, 225mm, 250mm, 300mm, 350mm, 400mm, 450mm., 500mm, 550mm, 600mm, other sizes can be also customized by the requirements.
