The ultra high power graphite electrodesale is produced by high grade needle coke, and its graphitization heat treatment is carried out in the internal series graphitization furnace. The graphitization temperature is up to 2800 ~ 3000°C, so the resistivity is lower, allowing for greater current density, smaller linear expansion coefficient and excellent thermal shock resistance.
In general, Graphite electrode mainly petroleum coke, needle coke as raw material, coal asphalt binder, is produced by the calcination, ingredients, kneading, etc, in electric arc furnace arc form conductor of electricity to heat melting furnace charge, according to its quality index, can be divided into ordinary power graphite electrode, high power graphite electrodeand ultra high power graphite electrode.
The main raw material for the production of ultra high power graphite electrode sale is petroleum coke. A small amount of asphalt coke can be added to the ordinary power graphite electrode. The sulfur content of petroleum coke and asphalt coke should not exceed 0.5%. Needle coke is also needed to produce high power or ultra high power graphite electrodes.
