摘要： Disclosed is a method for increasing the charring ratio of coal. In manufacturing an ingot iron using the coal, magnesium oxide or limestone is used as an additive for charring the coal. The additive increases the charring ratio of the coal while giving no affection onto slag. An MgO suspension or limestone suspension is mixed with the coal and thus obtained mixture is dried to attach MgO or the limestone onto the surface of the coal. The charring effect is increased and the using amount of coke can be reduced.

摘要： An apparatus and a method for manufacturing molten pig iron by using a fine iron ore are disclosed. Coal is used to produce a reducing gas, and a fine iron ore is used to produce a molten iron and a reduced iron in a simple and efficient manner. The apparatus for manufacturing a molten iron by directly using coal as the fuel is as follows. A high temperature reducing gas is sent from a melter-gasifier to a fluidized bed lime stone calcining furnace to calcine the lime stone. The reducing gas is supplied to a second fluidized bed reducing furnace so as to manufacture a reduced iron directly. An off-gas from the second fluidized bed reducing furnace is supplied to a first fluidized bed reducing furnace (disposed above the second fluidized bed reducing furnace) to pre-heat and pre-reduce the fine iron ore. The calcined lime stone and the finally reduced iron are supplied to a melter-gasifier to manufacture a molten pig iron.

摘要： A smelting reduction apparatus and a method for producing molten pig iron using the smelting reduction apparatus are disclosed. The molten pig iron is produced by using iron ore, sintered ore or iron pellets, so that the reduced iron discharge operation from a pre-reducing furnace to a melter-gasifier would not give any influence to the operation of the pre-reducing furnace. An iron ore is pre-reduced at a pre-reducing furnace by utilizing a reducing off-gas which is produced from a melter-gasifier. The pre-reduced iron ore is melted and reduced at the melter-gasifier. The reducing gas which is discharged from the melter-gasifier is supplied through an ascending duct and a cyclone into the pre-reducing furnace. The fine iron ore which is collected at the cyclone is spouted through a recycling device and a melter-burner into the melter-gasifier. A part of the reducing off-gas which has passed through the cyclone is supplied through a ventury scrubber, a compressor and a compressed gas circulating duct into the ascending duct. In such an apparatus, a reduced iron discharge device is installed between the pre-reducing furnace and the melter-gasifier.
