Graphite Electrode
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.
