Graphite electrode refers to a kind of high-temperature graphite conductive material made of petroleum coke and asphalt coke as aggregate and coal asphalt as binder through raw material calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization and mechanical processing, which is called artificial graphite electrode (referred to as graphite electrode).
Graphite electrodes are divided into 3 Types: RP Graphite electrodes,HP Graphite electrodes, UHP Graphite electrodes.
UHP Graphite Electrode. It is made of high-grade needle coke and treated with Lengthwise Graphitization (LWG). The graphitization temperature can be up to 2800 °C – 3000 °C. Finished products have lower electrical resistance & linear expansion, good thermal shock resistance and allow a larger current density.
HP Graphite Electrode. It adopts quality petroleum coke or low grade needle coke as raw material. Its physical and mechanical properties are higher than RP graphite electrode such as lower electrical resistance and allowing a greater current density.
RP Graphite Electrode. Ordinary grade petroleum coke is adopted for production. This type of graphite electrode is treated with low graphitization temperature. The allowable current density is lower than HP graphite electrode's. Regular power graphite electrodes are specified with allowable current density less t han 17 A/cm2.
Application
Graphite electrodes are mainly used in electric arc furnace. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in EAF. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.It plays an indispensable role in the high temperature manufacturing field such as iron and steel smelting, electrolytic aluminum, ferroalloy, calcium carbide, industrial silicon and yellow phosphorus smelting.
