Graphite & Carbon Electrodes is mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as binder, calcined, proportioned, kneaded, pressed, roasted, graphitized and machined. It is a conductor that releases electric energy in the form of electric arc 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 stone Ink electrode.
The main raw material of Graphite & Carbon Electrodes production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrode. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also needed to produce high power or ultra-high power graphite electrode. The main raw material for aluminum anode production is petroleum coke, and the sulfur content is controlled to be no more than 1.5% – 2%. Petroleum coke and asphalt coke shall meet the relevant national quality standards.
