China Small Size LF RP 250mm Graphite Electrode With Nipples 3TPI 4TPI

Grade: RP(Regular power)

Dia: 250mm 

Length: 1800+/-100mm 

Ordinary power graphite electrodes allow the use of graphite electrodes with a current density lower than 17A/cm2, which are mainly used in ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.

Anti-oxidation coating The surface of the graphite electrode is coated with a protective layer (graphite electrode antioxidant) that is both conductive and resistant to high temperature oxidation, which reduces the electrode consumption during steelmaking, prolongs the service life of the electrode, and reduces the power consumption of the electrode.

High-power graphite electrodes allow the use of graphite electrodes with a current density of 18A/cm2, mainly used in high-power electric arc furnaces for steelmaking.

Graphite electrode is mainly used petroleum coke and needle coke as raw materials and coal asphalt as binder through calcination, batching, kneading, molding, baking, graphitization and machining. It is a conductor that releases electric energy in the electric arc furnace to heat and melt the steel scrap. According to its specs, it can be divided into regular power graphite electrode, High power graphite electrode and Ultra-high power graphite electrode (RP HP and UHP).
