Masteel 1# blast furnace core temperature continues to drop,the total pressure difference level of the blast fur-nace is high,and the furnace condition fluctuates greatly in the process of adjusting the furnace condition.After the conver-sion of dry and wet coke,the furnace condition declines seriously,the air flow is uneven around the furnace wall,and the activity of the furnace cylinder continues to decline.Manganese ore and fluorite were used to wash the furnace to restore the furnace condition.After the furnace condition improved,the long plug outlet was gradually opened to restore the furnace condition,the air volume and oxygen volume were restored to 4 900 m3/min,9 000 m3/h,the load was 4.3,and the out-put was 6 200 t/d.The furnace condition fluctuated this time,due to the timely and decisive measures taken later.The de-terioration trend of furnace condition has been effectively curbed and restored.
