Graphitized petroleum coke can be divided into high temperature graphitization and medium temperature graphitization.
The high-temperature graphitized petroleum coke is the product of the Acheson calcining center, with a temperature of 3000 ℃ above,long-term calcination, complete graphitizaton. It is characterized by high fixed carbon, low gas impurity content, rapid dissolution and high recovery. It s the first choice for ductile cast iron for recarburization.
The medium-temperature graphitized petroleum coke is a thermal insulation layer of Acheson’s high temperature graphitized semi. The calcination temperature is in the range of 1700-2700 ℃.It belongs to medium-temperature graphitized products. Its characteristics as high fixed carbon, fast dissolution, high recovery,and moderate sulfur content(0.20-0.40%),low nitrogen content(800-2000 ppm),which is almost same lubrication and clear drawing like high-temperature graphitized petroleum coke. It can be widely used in recarburization of gray cast iron, which is of high cost-effective.
