Audited Supplier Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation, and corrosion resistance in high temperatures.Graphite electrode is widely used in EAF (for smelting steel),submerged-arc furnace (for producing Ferro alloy, pure silicon, phosphor, matte, calcium carbide, etc.)and electric resistance furnace, (such as graphitization furnace producing graphite electrodes, glass--melting furnace, electric furnaces producing carborundum, etc.)
Electric furnace steelmaking is the use of graphite electrode into the furnace current, strong current in the electrode at the bottom of the gas arc discharge, the use of the heat generated by the arc to smelting. According to the capacity of electric furnace, different diameter graphite electrodes are used. In order to make continuous use of electrodes, electrodes are connected by electrode thread joints. The graphite electrode used in steelmaking accounts for about 70 ~ 80% of the total amount of graphite electrode.
Graphite electrodes of EG/RP grade are used in electric arc, refining, ferroalloy and submerged-arc furnaces
