Description of Graphite Electrode：

The graphite electrode will be a high-temperature graphite conductive material, the core of which consists of petroleum coke, tar coke as a filler, coal tar as a binder. We produce graphite electrodes and nipples to them. Graphite electrodes are characterized by low resistance, good electrical conductivity and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc.According to its high quality and low quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.
