The carbon raiser is made from the raw materials of the best quality low sulphur petroleum coke, through the processing of calcining and graphitization in temperature of above 2400.

The carbon raiser is widely used in the fine steel smelting and fine casting, to increase the carbon content in the steel and castings efficiently, to change the chemical ingredients of the steel, and increase the hardness, strength and toughness of the steel, and avoid the break and chilling and improve the quality of the steel and castings.
