Abstract:
A direct charging device for directly charging a reduced fine iron ore into a melter-gasifier applied to a molten iron manufacturing apparatus having a fluidized bed final reducing furnace for finally reducing a fine iron ore, the final reducing furnace having a plurality of reduced fine iron ore discharging outlets for discharging a reduced fine iron ore to an outside of the final reducing furnace, and a melter-gasifier receiving general lump coal to form a coal packed bed within the melter-gasifier to manufacture a molten iron by receiving reduced fine iron ore from fluidized bed final reducing furnace,the direct charging device comprising:a plurality of reduced fine iron ore charging inlets formed around a circumference of a side wall, positioned at substantially angular intervals and inclined downwardly at an angle of about 20-45.degree., on the side wall of the melter-gasifier; anda plurality of reduced fine iron ore charging conduits connecting the reduced fine iron ore discharging outlets of the fluidized bed final reducing furnace to the reduced fine iron ore charging inlets, whereby reduced fine iron ore is continuously charged from the fluidized bed final reducing furnace into the coal packed bed of the melter-gasifier.
