Abstract：The experiences in handling long term blow-down of 2300m3 BF in Ling Steel were summarized，including holding temperature after blow-down；adding appropriate clean coke at the beginning of reblowing and more coal to make the blast temperature enough；reducing the basicity of slag to improve the slag liquidity；moderately adjusting the ore batch and burden distribution matrix to ensure the reasonable distribution of the two gas flow；hierarchically plugging the tuyere and reasonably arranging the blast furnace casthouse operation etc. Finally, it took only 24h to make the furnace condition normal after reblowing.
