Carbon Additive also called Calcined anthracite Coal, Gas Calcined Anthracite Coal, Carbon Raiser,Recarburizer,etc. The main raw material of our Carbon Additive is Ningxia unique high quality Taixi anthracite, with characteristic of low ash andlow sulfur. Carbon additive has two main usage, fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%. Best quality Taixi anthracite as raw materials through high temperature calcined at 800-1200 â?? by the DC electric calciner with results in eliminating the moisture and volatile matter from Anthracite efficiently, improving the density and the electric conductivity and strengtheningthe mechanical strength and anti-oxidation, It has good characteristics with low ash, low resistivity, low carbon and high density. It is the best material for high quality carbon products, it is used as carbon additive in steel industry or fuel.
