Graphite petroleum coke is a kind of low sulphur, low nitrogen Recarburizer, it is made from low sulfur and low nitrogen petroleum coke by graphitizing process in advanced automotive production line with independent intellectual property rights. As a high purity carbon material, it has characteristics of high fixed carbon content, low ash, low sulfur, low resistance etc. with stable effect for improving the carbon content, high absorptive of carbon.
Graphitized Petroleum coke is mainly used for metallurgy & foundry, it can improve the carbon content in steel-melting and casting, Also it can increase the quantity of scrap steel and reduce the quantity of pig iron, or use no scrap iron at all.
