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 has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power.
Graphite electrodes are divided into 3 Types: RP Graphite electrodes,HP Graphite electrodes, UHP Graphite electrodes.
| Picture | Type | Index |
 |
RP Graphite electrodes | Graphite electrodes with current density less than 17A/ cm 2 are allowed to be used, mainly for ordinary power electric furnaces such as steel, silicon, and yellow phosphorus smelting. |
| HP Graphite electrodes | Graphite electrodes with a current density of 18 to 25A/ cm 2 are allowed to be used, mainly for high-power arc furnaces for steelmaking. | |
| UHP Graphite electrodes | Graphite electrodes with a current density greater than 25A/ cm 2 are allowed to be used, mainly for ultra-high power steelmaking arc furnaces |
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.
