3rd grade anthracite based of carbon additive

3rd  grade anthracite based carbon additive it is produced from high quality anthracite under high temperature .

It's F.C can be 92% Min,ash content 6.5% max  and mainly  be used for steelmaking in electrical, foundry

industry to increase the content of carbon.

Using Methods of Carbon Additive 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.

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
