Document Type and Number:
Japanese Patent JP2008506041
Kind Code:
A
Abstract:
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.
