There are currently three blast furnaces in New Area of Tangshan Iron and Steel Company,which frequently shut down for long periods after being put into operation.After a long period of wind break,problems such as the initial heat adjustment,iron tapping organization,and airflow fluctuations are particularly prominent in the early stage of furnace recov-ery,leading to difficulties in increasing air volume and a longer recovery time for furnace conditions.In order to reduce the impact of long-term wind break on blast furnace production,the links that affect the recovery of furnace conditions has opti-mize,and the recovery time of air volume has been shortened from more than 48 hours to less than 30 hours.
