ABSTRACT:
A method for manufacturing molten iron that improves charging and discharge of the fine iron ore, and an apparatus for manufacturing molten iron using the same. The apparatus for manufacturing molten iron includes i) at least one fluidized-bed reduction reactor that reduces fine iron ore and converts the fine iron ore into reduced iron, ii) a fine iron ore charging bin that supplies the fine iron ore to the fluidized-bed reduction reactor, iii) a fine iron ore charging line that directly connects the fine iron ore charging bin to each of the fluidized-bed reduction reactors, and directly charges the fine iron ore into each of the fluidized-bed reduction reactor, iv) a melter-gasifier into which lumped carbonaceous materials and the reduced iron are charged and oxygen is injected, the melter-gasifier manufacturing molten iron, and v) a reducing gas supply line that supplies a reducing gas discharged from the melter-gasifier to the fluidized-bed reduction reactor.
