Graphite electrode is mainly from the domestic petroleum coke and imported needle coke, graphite electrodes are widely used in electric arc furnace, ladle furnace, submerged arc electric furnace for the production of alloy steel, metal and nonmetallic materials. Our graphite electrodes include regular power, high power, super high power and ultra high power. They are characterized by low resistivity, good electric and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, ect.

Graphite Electrode Description

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.

Properties of Graphite Electrode

.Low electric resistance,
.High density,
