What is Smelting and Lining?

Our Smelting and Lining business consists of three product types: Cathodes for aluminum smelters, Lining blocks for blast furnaces, and Carbon Electrodes for submerged arc furnaces. Cathode blocks we supply are installed as cathodes at the hearth of aluminum smelting furnaces and used for electrolysis in combination with anodes as their counter electrodes. Since cathodes gradually wear during use, they are to be replaced in 4 to 6 year cycles. Lining blocks for blast furnaces are carbon or graphite-based refractory materials used to line the inner part of blast furnaces for iron production. Carbon electrodes are used in production processes such as for silicon metal, ferroalloys and phosphorous, copper and etc.We hold world-leading market shares in those three major products driving the industry with production capabilities, global customer base and quality-related technology.
