Product Description

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.
