It is 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. Anthracite based carbon additive.

Carbon additive enhancers

      In the smelting process, due to improper ingredients or loading and excessive decarbonization 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.

Carbon additive apply

Used for casting, cast iron, cast steel, cast will have a requirement for carbon, carbon additive just as its name implies is to increase the carbon content in liquid iron, and, for example, commonly used in smelting furnace charge for pig iron, scrap steel, back to the furnace charge, iron carbon content is high, but relatively scrap purchase price is higher section, so adding scrap supply, reduce the quantity of pig iron, increase carbon agent, can reduce the casting cost play a role. The use of carbonizing agent can not only make up the loss of carbon in the process of steel smelting and ensure the carbon content of specific grade of steel, but also be used to adjust after furnace. Carbon additive As an important raw material for melting molten iron in induction furnace, the quality and usage of carbon additive directly affect the state of molten iron.

The type of carbon additive

 There are many materials that can be used as a carburizer for cast iron, such as artificial graphite, calcined petroleum coke, natural graphite, coke, anthracite, and mixtures of such materials.
