Anthracite based carbon additive

Anthracite based carbon additive which made from Ningxia Taixi anthracite as raw material, after fine washing, selection, in 1250℃ high temperature conditions dry distillation to reduce volatilization, increase fixed carbon content, density and strength, improve oxidation resistance. 

In the smelting process, due to improper ingredients or loading and excessive recarbonization and other reasons, sometimes the carbon content in steel does not meet the requirements of the peak period, at this time to the molten steel to increase carbon.

 The commonly used carbon additive agents are carbon additive pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting high carbon steel in converter, petroleum Jiaozuo with little impurity is used as carbonizing agent. The requirement of  carbon additive for top blowing converter steelmaking is that the fixed carbon should be high, the content of ash, volatile matter and impurities such as sulfur, phosphorus and nitrogen should be low, and dry, clean and moderate particle size.

We can promise to compensate all the amount of the contract if any problem for our goods. It must be approved and certified by the third party's independent Inspection Authority.
