In order to cope with the contradiction of iron firing balance caused by two sintering machines in turn,the 3200m3 blast furnace of Shaogang was forced to carry out a large proportion of pellet smelting. Through advance planning,strengthening the adjustment and optimization of the furnace top fabric matrix,reducing the tuyre area and increasing the blast dynamic energy,optimizing the slag composition and maintaining the appropriate magnesium to aluminum ratio,and other measures,good production results were achieved to ensure the stable running of the blast furnace.
