UHP graphite electrodes are mainly produced from needle coke and pitch coke, which are high-temperature resistant conductor materials. It is mainly used in electric arc furnace steelmaking. High-quality graphite electrodes can reduce ton consumption and improve production efficiency. Normally, the consumption per ton of steel for our UHP 600 graphite electrode is 0.9kg.

Manufacturing using high-quality needle coke
Using high-quality needle coke and modified pitch binder to develop high-quality UHP graphite electrodes makes high-energy load resistance and high-current operation possible.
With the development of the industrial economy, many countries have reformed. They are actively stipulating the self-sufficiency system of steel production.They have introduced electric arc furnace steelmaking one after another.
