| Abstract: | Leiwu Steel＇s 1880m3 BF can resume the furnace condition rapidly by careful operation after damping-down in stable smooth operation for long time.The main methods are as follows：doing well the prophase preparation;discharging slag and hot metal in time,doing well the heat preservation of the hearth and controlling proper water pressure,water quantity and the top temperature in damping-down;and in reblowing,processing the air volume,achieving to fill ore and coke according to stock level,adjusting well flame temperature and doing well the first tapping.The blast furnace ever recovered the whole blast pressure operation within 5 hours after planned maintenance for 73 hours and the furnace condition was stable smooth. |
