摘要：

Based on the 8 main blast furnaces at Ansteel, a database was established using charging system parameters and blast furnace smelting parameters to conduct correlation studies. The effects of specific blast furnace charging parameters on furnace performance were analyzed, revealing the influence patterns of edge coke load, drop point distance, and ore-free zone proportion. A comprehensive management system for the charging process was developed, translating the burden matrix into a set of characteristic parameters. By defining control intervals for these parameters, the system enhances the precision and effectiveness of charge regulation, ensuring a more scientifically optimized charging operation. After implementation in 2022, the economic indicators of the blast furnace group showed significant improvement, with the overall fuel consumption per ton of molten iron decreasing by 5 kg/t compared to 2021.
