Graphite electrodes are widely used in electric arc furnaces for steelmaking. Its main function is to introduce current into the eaf after energization, and use the high-temperature heat source generated by the arc between the electrode end and the charge to perform metallurgy. Graphite electrode is a good conductor for heating and melting the furnace charge.
Graphite electrode is an important industrial raw material used in electric arc furnace smelting and steel production. It is mainly made of petroleum coke, needle coke and asphalt, and is processed through processes such as pressing, roasting and high-temperature graphitization.
Advantage
Good electrical conductivity; high thermal stability; high mechanical strength; good corrosion resistance.
Application
HP graphite electrodes are widely used in electric arc furnaces for smelting in steel, non-ferrous metals, chemicals and other industries.
