详细描述
Graphite electrode is a new generation electrode product we research. This product have good reputation from domestic and foreign customers because of the best quality and perfect after-sale service. Graphite electrode is mainly used for metallurgy industry and calcium carbide, phosphor-chemical enterprise, such as iron and steel smelting, industrial silicon, yellow phosphorous, ferroalloy, titania slag, brown fused alumina etc submerged - arc furnace melting production.
