Product Description

Graphite electrode is made of high-quality calcined petroleum coke, needle coke and coal pitch, which can be divided into three specifications: regular power(RP), high power(HP) and ultra-high power(UHP), with a diameter range of 50-700mm.

It is widely used in electric arc furnaces and submerged arc furnaces to smelt various alloy steels, yellow phosphorus, industrial silicon, brown corundum, and other alloy and non-metallic materials.
