摘要： The present invention relates to an apparatus for manufacturing compacted irons and an apparatus for manufacturing molten irons using the same. The apparatus for manufacturing compacted irons according to the present invention includes a charging hopper into which reduced materials containing fine reduced irons are charged, screw feeders installed inside the charging hopper to make an acute angle with a vertical direction and discharging the reduced materials containing fine reduced irons which enter into the charging hopper, and a couple of rolls separated from each other to form a gap between the rolls. The couple of rolls compact the reduced materials containing fine reduced irons discharged from the charging hopper by the screw feeders and manufacture compacted irons. Each screw feeders is arranged side by side along an axis direction of the couple of rolls and an extension of the center axis of each screw feeder passes through the gap.

摘要： An apparatus for manufacturing molten iron includes a reduction furnace having a charging device that is capable of preventing segregation. The reduction furnace for reducing an iron-containing material used for manufacturing molten iron may include a charging hole where the iron-containing material is charged, a first guide plate sloped toward a first direction in the reduction furnace to guide the iron-containing material to the inside of the reduction furnace, and a second guide plate fixed and sloped toward a second direction intersecting the first direction in the reduction furnace to guide the iron-containing material dropped and guided by the first guide plate. A dropping direction of the iron-containing material dropped and guided by the first guide plate is changed when the iron-containing material is guided by the second guide plate.
