4th Anthracite Based Carbon Additive

4th Anthracite Based Carbon Additive ,it's F.C can be 90% Min and mainly used for steelmaking in electrical, foundry industry to increase the content of carbon.

It is produced from high quality anthracite under high temperature in  furnace.

  Carbon Additive using methods for steelmaking plant / F.C. 90-95% Calcined Anthracite: 

1) Adjust carbon points, put into the central lower part of furnace with metal, the yield can reach 90% - 95%; 

2) Adjust the carbon after the molten steel melt, put it on the surface of molten steel.

 Finally, the rate is about 85% by molten steels swirl stirring or Artificial mixing.

At present, there are 3 kinds of commonly used carburetant:
First, graphite powder, which is a vacuum powder by graphite electrode processing.
Second after petroleum coke, which is used in some domestic steel plant to make of carburizing agent.
Third is the graphitized petroleum coke, which is also used as recarburizer in steel making.
Induction furnace carburizing; cupola furnace carburizing; double process carburizing; furnace ladle with the current carburizing
