Hot Sale Graphite Petroleum Coke Gpc Powder

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 a above, long-term calcination, and 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 a . 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 the same lubrication and clear drawing like high-temperature graphitized petroleum coke. It can be widely used in the recarburization of gray cast iron, which is of high cost-effective.
