Calcination temperature is normally about 1300 °C, for the purpose of petroleum coke as much as possible to remove the volatile matter. This will help to reduce petroleum coke and then the hydrogen content of products, so that the graphitization of petroleum coke increased, thereby enhancing the strength of graphite electrodes and the high-temperature heat resistance and improve the electrical conductivity of the graphite electrode. Mainly used in the production of calcined coke graphite electrode, carbon paste products, carborundum, food-grade phosphate industry, metallurgical industry and calcium carbide and so on, which is the most widely used graphite electrodes. Aluminum industry consumed about calcined coke calcined coke consumption in the world of 75%. Per ton of aluminum production will consume about 0.4 tons of carbon anode. Aluminum industry consumes most of the calcined petroleum coke, and the remaining 25% of the calcined petroleum coke is used: the production of titanium dioxide, iron and steel and other chemical production process.
