Product Description

Production: 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.

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.
 
 Grade: Graphite electrodes are divided into 3 Types: RP Graphite electrodes, HP Graphite electrodes, UHP Graphite electrodes.
