Refractory Metallurgical Auxiliary Material CAC Calcined Anthracite Coal
Calcined Anthracite Coal (CAC) Refractory Materials Iron and steel smelting
Product introduction
Calcined anthracite coal is produced when anthracite is calcined under the temperature of 1240°C in vertical shaft furnaces with results of eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation. It has good characteristics with low ash, low resistivity, low sulphur, high carbon and high density. It is widely used as carbon additive in electric furnaces in steel industry, it can also be used in water filtering, rust removal in shipbuilding and production of carbon material.
