Recarburizer, also know as carbon additive, carbon raiser. It is a product for increasing the carbon element (C).
Product Description
   During the steel making process, various factors may cause the carbon content in the molten steel to decrease. This will affect the quality of the finished steel. So, steel mills usually purchase carbon reductants to cope with the decline in carbon emissions.

 Calcined petroleum coke(CPC)

The carbon content is generally 96% -99%. The sulfur content is 0.3-0.7%. What is calcined petroleum coke used for? It is mainly used in steelmaking, cast iron, brake pads, cored wires and so on.

Carbon Raiser F.C% V.M% Ash% S% Moisture
CPC-01 98.5min 0.5max 0.3max 0.45max 0.3max
CPC-02 98.5min 0.5max 0.5max 0.5max 0.3max
CPC-03 98-99min 0.5max 1.00-0.3max 0.5max 0.3max

 Graphite petroleum coke(GPC)

The carbon content is 98-99.5%. The sulfur content is 0.05-0.03%. Mainly used for nodular cast iron. It is characterized by fast absorption, high carbon and low sulfur.

Carbon Raiser F.C% V.M% Ash% S% Moisture
GPC 98-99.5min 0.5max 0.3max 0.05-0.03max 1max

In addition to the above two recarburizers, metallurgical coke recarburizers and calcined coal recarburizers are also available. The specifications are as follows:

Carbon Raiser F.C% V.M% Ash% S% Moisture
Metallurgical coke 85max 1max 15-18 1 1max
Calcined anthracite 91-95 1max 4-8 0.4-0.6 1max

Main application of recarburizer

  •  To add carbon raiser in foundry process can greatly increase the consumption of steel scrap, reduce the consumption of pig iron, or do n’t even use pig iron.
  •  Carbon raiser is mainly used in steelmaking. Used to increase the carbon content of steel. Carbon raiser used in high carbon steel smelting due to its high quality with few impurities.
  •  Carbon additive can also be used in foundries. Used to reduce impurities in pig iron, thereby reducing casting costs.
