Graphitized petroleum coke(GPC)

Graphitized Petroleum Coke 

The high-temperature graphitized petroleum coke is the product of the Acheson calcining center, with a temperature of 3000 ℃ above.long-term calcination, complete graphitization.It is characterized by high fixed carbon, low gas impurity content, rapid dissolution and high recovery. It is the first choice for ductie 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 recarborization of gray cast iron,which is of high cost-effective.

Graphite instant columnar recarburizer is one kind of high cost-performance graphitized carburizer The particle size is moderate,the porosity is large, and the absorption speed is fast. The chemical composition is high in carbon, low in sulfur, has high absorption rate. It could help reduce smelting production costs, improve the quality of smelting metals and castings, and allow smelting of metal plants and casting.
