Graphite electrode

Graphite electrode is mainly made of petroleum coke, needle coke as raw material, coal tar binder, after calcination, ingredients, kneading31, pressure type, roasting, graphitization, machining and is in the electric arc furnace to release electric energy in the form of an arc Conductors on the melting furnace charge, according to its level of quality indicators, can be divided into ordinary power graphite electrodes, high-power graphite electrodes and ultra-high power graphite electrodes.

Graphite electrode production of the main raw material for the petroleum coke, ordinary power graphite electrode can be added a small amount of asphalt coke, petroleum coke and pitch coke sulfur content can not exceed 0.5%. Need to add needle coke when producing high-power or ultra-high-power graphite electrodes. Aluminum anode production of the main raw material for the petroleum coke, and control of sulfur content of not more than 1.5% to 2%, petroleum coke and pitch coke should meet the relevant national quality standards.
