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.
Adding graphitized petroleum coke recarburizer in casting can greatly increase the amount of scrap steel added, reduce the amount of pig iron input, and greatly reduce the production cost.
Graphitized petroleum coke recarburizer has high purity and contains almost no impurities, which guarantees the excellent performance of castings to a large extent.
