PRODUCT DESCRIPTION
The high-temperature graphitized petroleum coke is the product of the Acheson calcining center, with a temperature of 3000'C above, long-term calcination. complete graphation.lt is characterized by high fixed carbon, low gas impurity content,rapid dissolution and high recovery. lt is the first choice for ductile cast iron for recarburization.
The medium-temperature graphitized petroleum coke is a thermal layer of Acheson's high temperature graphed semi. The calcination temperature is in the range of 1700-2700'c. lt belongs to medium-temperature graphed products. lts 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. lt can be widely used in recarburization of gray cast iron, which is of high cost-effective.
