Description of Graphite Electrodes
The graphite electrode is mainly made of petroleum coke and needle coke, and the coal bitumen is used as a binder. It is made by calcination, compounding, kneading, pressing, roasting, graphitization and machining. According to its quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
Features of Graphite Electrodes
1.Low ash
2.Good oxidation resistance
3.High mechanical strength

5.Easily and fast to be produced
6.Low resistivity
7.Low graphite loss
8.Compact structure
9.High discharge removal rate
