THE OPERATION OF LONG TIME-DAMPING DOWN AND RAPID RECOVERY OF THE BLAST FURNACE IN NEW AREA OF TANGSHAN IRON AND STEEL COMPANY
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.
