Calcined petroleum coke is mainly used for pre-baked anodes and cathodes for electrolysis of aluminum, carbon additives for metallurgy and steel production, graphite electrodes, industrial silicon, yellow phosphorus, and carbon electrodes for ferroalloys. Therefore, both electrolytic aluminum plants, independent carbon plants and oil refineries pay more attention to the progress and development of petroleum coke calcining technology.

　　Seeing that calcined petroleum coke has so many functions, it is necessary to vigorously develop new production skills to further improve the use of calcined petroleum coke. In particular, the domestic calcined petroleum coke calciner still has a lot of room for technological development. It should focus on the application of new materials, the development of high-quality silica bricks, the recovery of waste heat resources in multiple ways, the improvement of automation, scientific ovens and standardized operations, etc. In-depth research is carried out to make the use rate of calcined petroleum coke higher and the use effect better. In addition, the smelting furnace should develop a long life, high productivity, intelligent environmental protection, and economical industrial furnace. Particular attention should be paid to the combination of numerical simulation technology and production practice to scientifically improve the quality and technical issues of my country's calcined petroleum coke, so as to further reduce production costs and improve production efficiency.
