Semi-Graphite Petroleum Coke

It is the insulation layer of Acheson’s high-temperature graphitized semi-finished products. The calcination temperature is in the range of 1700-2700°C. It is a medium temperature graphite product. It is characterized by high fixed carbon content, fast dissolution rate, high recovery rate, moderate sulfur content (0.20-0.40%), low nitrogen content (800-2000 ppm), almost the same as high-temperature graphitized petroleum coke, and clear lubricity and stretchability. It can be widely used for recalcining gray cast iron and is highly cost-effective.
