1.Features:

Calcined Anthracite Coal also called Carbon Additive, Gas Calcined Anthracite Coal, Carbon Raiser.

The main raw material is Ningxia unique high quality anthracite, with characteristic of low ash and low sulfur. Carbon additive has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above *5%.

Best quality Anthracite as raw materials through high temperature calcined at over ***0  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 strengthening the 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.

2.Applications:

Calcined Anthracite Coal/Carbon Additive 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 ***6K/KG. It may substitute burnt carbon massively. The burnt carbon exportation needs the quota; therefore the carburizing agent price superiority is similarly obvious.

Calcined Anthracite is produced when Anthracite is calcined under the temperature of ***0  in vertical shaft furnaces.Calcined Anthracite is mainly used in electric steel ovens, water filtering, rust removal in shipbuilding and production of carbon material
