摘要： PROBLEM TO BE SOLVED: To prevent the lowering of a heat level at the lower part of a furnace while sufficiently executing the reduction of ore at the time of operating at high O/C and to reduce the producing cost of molten iron while continuing stable operation by injecting a large quantity of pulverized fine coal from a tuyere in a blast furnace and charging the roe having high reducibility from the furnace top. SOLUTION: The pulverized fine coal is injected at >=160 kg/t-p from the tuyere in the blast furnace and while alternately charging the ore and coke from the furnace top in layers, the high O/C operation is executed and the charging quantity of the coke is reduced. At this time, the ore kind having high reducibility to 1200 deg.C is charged on the upper layer in each ore layer, desirably charged at 20-50 mass % of each ore layer. By this method, the dripping temp. of the reduced ore is raised and the lowering of the heat level at the lower part of the furnace is prevented and the stable operation can be obtd. without remarkably increasing the fuel ratio. This reducibility is evaluated when the are can be reduced at >=60% with the gas of CO:N2 =3:7 while raising the temp. to 1200 deg.C at 7 deg.C/min after reducing to wustite with gaseous mixture of CO:CO2 =1:1 matching to the furnace condition.
