Claim:
An apparatus for manufacturing molten irons, the apparatus comprising: at least one fluidized-bed reduction reactor that reduces and plasticizes iron ore and converts the iron ore into reduced materials; a melter-gasifier into which the reduced ore is 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 fluidized-bed reduction reactor comprises a cyclone that is installed in the fluidized-bed reduction reactor to collect fine iron ore, the cyclone comprising a cone portion that collects the fine iron ore and a dipleg portion that is connected to a lower end of the cone portion and discharges the collected fine iron ore, and wherein at least one gas injector, which prevents the fine ore from adhering by injecting gas containing carbon, is connected to the dipleg portion of the cyclone.
