In steelmaking and casting, in order to make the carbon content in the molten iron reach the predetermined technical indicators, it is usually necessary to add a certain amount of recarburizer. Graphitized petroleum coke recarburizer is widely used by most steel plants. Graphite recarburizer is made from petroleum coke after graphitization treatment at about 2500℃ – 3000℃.
Graphitized petroleum coke recarburizer (GPC carbon raiser) presents the same molecular structure as graphite microscopically. And its content of impurities such as sulfur, nitrogen, moisture and ash are all at a very low level, so as to increase the carbon content of molten iron without increasing new impurities.
