Baosteel ironmaking always strives to become optimization of ironmaking as a goal, and in the context of external conditions deterioration, always focus on the basic principles of stable and smooth running of blast furnace. Through strengthening blast furnace raw material management, and constantly optimizing the operation system, the rational distribution of gas flow in blast furnace and high utilization rate of gas are realized. Through adopting dry type bag filter cleaning technology, pure water closed circulating system and improving TRT, hot stove residual heat recovery equipment and other energy-saving equipment energy saving effect, fuel ratio and energy consumption of blast furnace are decreased continuously, the low carbon production of blast furnace is realized.
