Practice of Long Cycle Stable,High Efficiency and Low Consumption Production of Blast Furnace
With the core of stable,efficient and low-consumption smelting of blast furnaces,a quality control and stability system for controlling the particle size composition of raw materials and fuels entering the furnace,a high-magnesium pellet preparation process,and a monitoring software for the active state of the hearth have been developed.The harmful element control standards and early warning mechanism of blast furnaces,the three-level classification standards for sintering ore powder based on grade,the maintenance standards for key equipment of blast furnaces,and the evaluation system for utilization rate of blast furnace gas have been established.The integration of blast furnace equipment and the long-term low-blow down rate operation of blast furnaces is achieved.The maintenance cycle of blast furnaces has been extended to 6-9 months,fuel ratio is 522.42 kg/t.
