Carbon raiser/Recarburizer/Carbon Additive is a big category that includes calcined petroleum coke(CPC), graphite petroleum coke(GPC), calcined anthracite coal(CAC), and natural graphite. Due to the high price of natural graphite, it is not suitable for steelmaking or casting, so calcined petroleum coke, graphite petroleum coke, and calcined coal are more suitable for the current steelmaking and casting process.

Applications
Metallurgical Coke Carbon additive manufacture,Steel making,Cement plants,Power plants,Vitrified tile manufacturers,clay bricks manufacturers,chemical industries,refractories and coal gasifier plants. Carbon raiser is a carbon material, produced at high temperatures and used for carburization of steel and cast iron. It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.
