Graphite electrode is divided into ordinary power graphite electrode, high power graphite electrode and ultra-high power graphite electrode. The flagship product of Henan Liugong is ultra-high power graphite electrode, which is exported to Europe, America, Southeast Asia, Australia and other countries, with an annual export volume of more than 100 million yuan.

The production process of ultra-high power graphite electrode requires high requirements for raw materials. It is mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as binder, calcined, proportioned, kneaded, profiled, roasted, graphitized and machined. It is a conductor that releases electric energy in the form of electric arc in the electric arc furnace to heat and melt the furnace charge. According to its quality index, it can be divided into ordinary power graphite electrode High power graphite electrode and ultra-high power graphite electrode.

The main raw material for graphite electrode production is petroleum coke. A small amount of asphalt coke can be added to ordinary power graphite electrode. The sulfur content of petroleum coke and asphalt coke shall not exceed 0.5%. Needle coke is also needed to produce high power or ultra-high power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and the sulfur content shall not be greater than 1.5% ~ 2%. Petroleum coke and asphalt coke shall meet relevant national quality standards.
