Recovery Method of Flow Abnormal Distribution in Laiwu Steel’s No.1 1 880 m3 BF
YANG Lei
Abstract：Laiwu Steel’s No.1 1 880 m3 BF for continuous single casthouse, slag and iron out without a net, central gas flow by plugging and weak, resulting in gas flow maldistribution, rising hot load of the furnace, furnace temperature and the temperature of molten iron decreased, resulting in abnormal furnace condition. In addition, furnace temperature and hot metal heat decrease. By sharply lowering coke load, continuous under blowing, blowing-down measureing material angle, reinforce iron tapping methods, furnace condition returns to normal after a week.
