graphite electrode for EAF LF
Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity ,thermal conductivity ,high mechanical strength, oxidation and corrosion resistance in high temperature .Graphite electrode is typically used in EAF (for smelting steel),submerged arc furnace (for producing ferroalloy ,pure silicon, phosphor, matte ,calcium carbide ,etc. And electric resistance furnace ,such as graphitization furnace producing graphite electrodes, glass-melting furnace ,electric furnaces producing carborundum, etc.
Graphite electrodes are classified into RP,HD,HP and UHP.
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. Graphite electrodes are divided into 3 Types: RP Graphite electrodes, HP Graphite electrodes, UHP Graphite electrodes.
Graphite electrode mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading,molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, with low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance, high mechanical strength, etc. Please contact us if necessary.
