UHP 500 To700MM 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. UHP graphite electrode is usually used as conductor of large capacity electric arc furnace. The intense electric arc generated between UHP graphite electrode and bottom electrode can heat and melt furnace load.
