UHP Graphite Electrode

UHP graphite electrodes with current densities greater than 25 A / cm2 are acceptable. UHP graphite electrodes mainly used in ultra-high power steelmaking electric arc furnace.

Graphite electrode is mainly made of petroleum coke, needle coke as raw material, coal pitch as binder, after calcination, ingredients, kneading, pressing, roasting, graphitization, machining and released in the electric arc furnace steelmaking in the form of an arc Electric energy as a conductor to heat the melting furnace. According to graphite electrode quality indicators, can be divided into ordinary power graphite electrode, HP graphite electrode and UHP graphite electrode.
