Petroleum coke powder that has been calcined is an essential material for numerous industries. It is primarily utilized as a prebaked anode and cathode for the electrolytic aluminum industry. Additionally, it serves as a carburizer and graphite electrode for the metallurgical steel industry, as well as a carbon electrode for industrial silicon, yellow phosphorus, and ferroalloy. As a result, the refinement and expansion of petroleum coke calcination technology is a top priority for both oil refineries and independent carbon plants, as well as electrolytic aluminum facilities.
To enhance the domestic production of calcined petroleum coke, there remains ample scope for technical advancement in calciners. It is crucial to delve into extensive research on novel materials' applications, foster the development of superior-quality silica bricks, implement multi-channel waste heat resource recovery, enhance automation, introduce scientific oven drying techniques, and encourage standardized operations. These measures will undoubtedly elevate the utilization rate and efficacy of calcined petroleum coke. Furthermore, it is imperative to design long-lasting, high-capacity, intelligent, environmentally friendly, and economically viable smelting furnaces to meet the industry's needs.
