The main raw material is unique high quality anthracite, with characteristic of low ash and low sulfur. Gas Calcined Anthracite Coal, Carbon additive has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting.
It may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel, for its calorific value may achieve above 9386K/KG.
It may substitute burnt carbon massively. The burnt carbon exportation needs the quota; therefore the carburizing agent price superiority is similarly obvious.
