Patent ID: 7850902

Claim:
An apparatus for manufacturing molten iron, the apparatus comprising: at least one fluidized-bed reduction reactor that reduces fine iron ore and converts the fine iron ore into reduced iron; a fine iron ore charging bin that supplies the fine iron ore to the fluidized-bed reduction reactor; a fine iron ore charging line that directly connects the fine iron ore charging bin to the at least one fluidized-bed reduction reactor, and directly charges the fine iron ore into the at least one fluidized-bed reduction reactor; 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 a reducing gas supply line that supplies a reducing gas discharged from the melter-gasifier to the fluidized-bed reduction reactor, wherein the fine iron ore charging line comprises: a sub-fine iron ore charging line that is connected to the fine iron ore charging bin; and a branch fine iron ore charging line that is branched from the sub-fine iron ore charging line and is connected to each of the fluidized-bed reduction reactor.
