Product Description
Factory Price High Power 200-700mm Graphite Electrode, UHP Graphite Electrode for Eaf Arc Furnace
Description:
Graphite electrodes are mainly made of petroleum coke and needle coke as raw materials, coal tar as binder, and are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electric energy in the form of arc in an electric arc furnace to heat and melt the charge. According to their quality indicators, they can be divided into ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes.
The main raw material for the production of graphite electrodes is petroleum coke. A small amount of asphalt coke can be added to ordinary power graphite electrodes. The sulfur content of petroleum coke and asphalt coke cannot exceed 0.5%. Needle coke is also required when producing high power or ultra-high power graphite electrodes. The main raw material for the production of aluminum anodes is petroleum coke, and the sulfur content is controlled to be no more than 1.5% to 2%. Petroleum coke and asphalt coke should meet the relevant national quality standards.

Graphite Electrode is made of high-quality low ash materials, such as petroleum coke, needle coke and coal pitch.after calcining,burdening,kneading,forming,baking and pressure impregnation, graphitization and then precision machined with professional CNC machining. Low resistivity, good electrical conductivity ,low ash, compact structure,good anti oxidation and high mechanical strength, Widely used in LF, EAF for steel making industry, Non-ferrous industry, silicon and phosphorus industry.so it is the best conductive material for electric arc furnace and smelting furnace.
Application Of Graphite electrodes: Graphite electrodes are used mainly in ladle furnaces,electric-arc furnace steelmaking, Industrial silicon furnace or melting copper. 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
