Our company adhering to the graphite electrode production experience for many years, with its excellent quality and perfect after-sales service, won the praise of customers at home and abroad. Graphite electrode can be used for ore heat furnace, resistance furnace, used for smelting of ferroalloys. Graphite electrode produced by our company is widely used in steel smelting.
Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as a binder, and are made by calcination, batching, kneading, compaction, roasting, graphitization, and machining. It releases electric energy in the form of electric arc in an electric arc furnace. Conductor for heating and melting the charge.
