The artificial graphite selects electrode imported needle coke, high quality low sulfur petroleum, modified pitch and other raw materials in low ash through calcination, batching, kneading, molding, multiple roasting, impregnation, graphitization ,polishing to finish the manufacture.
Ultra high power graphite electrode uses imported needle coke ,petroleum coke as main material and asphalt as binder. If the diameter is ≤400mm, the resistance is ≤5.8. If the diameter is ≥450mm, the resistance is ≤5.8. And the current load is between17A/Cm3 -30A/Cm3.
