Carbon raiser, also could be called Carbon additive, which is made from well-selected petroleum coke which is low in content of
ash, sulfur, phosphorus, high heat productivity, high chemically activation.
1. Mainly used in steelmaking in electrical stove, can improve the carbon content in steel-melting and Ductile iron foundry.
2. Reduce the cost of steelmaking effectively by replacing the traditional carburant
3. Metallurgy , casting for glass production/graphite crucible/anodes for the aluminium, titanim smelting industry.

Calcined Petroleum Coke comes from delayed coke which extracted from oil refinery. Although Calcined Petroleum Coke contains a little bit higher level of sulfur and nitrogen than pitch coke, the price advantage still makes it widely used during steel-making and founding as a kind of carbon additive/carburant.
