UHP graphite electrode is usually used as conductor of large capacity electric arc furnace.
What is uhp graphite electrodes?
UHP graphite electrodes meaning is ultra high power, According to the rate power, graphite electrodes can be divided into regular power (RP) graphite electrode, high power (HP) graphite electrode, ultra high power (UHP) graphite electrode.
UHP graphite electrode refers to a kind of ultra high power graphite based electricity conduction material, which adopts petroleum coke, needle shaped coke as aggregate, coal asphalt as binder, and are processed by complex crafts such as calcining, crushing, milling, batching, mixing, forming, roasting, impregnating, graphitization and mechanical processing.
