Graphite Electrode Product Description
Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials and coal tar pitch as binder. They are made by calcining, batching, kneading, pressing, roasting, graphitization, and machining. They release electric energy in the form of arcs in an electric arc furnace. The conductors that heat and melt the charge can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes according to their quality indicators.
The main raw material for graphite electrode production is petroleum coke. A small amount of pitch coke can be added to ordinary power graphite electrodes. The sulfur content of both petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required 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 is controlled to be no more than 1.5% to 2%. The petroleum coke and pitch coke should meet the relevant national quality standards
Application Of Graphite electrodes: Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking,Yellow phosphorus furnace , Industrial silicon furnace or melting copper. 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 this demanding environment.High Quality Needle Coke in HP&UHP graphite electrode,ensure the electrode application is perfect. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes.
Characteristics Of Graphite electrodes: Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capability, precise machining accuracy, especially with low sulphur and low ash will not give steel second time
