ABSTRACT:
In a method and an apparatus for cooling a reduced-iron agglomerate in a reduced-iron agglomerate production equipment wherein an iron oxide agglomerate is reduced in a reducing furnace and discharged as a reduced-iron agglomerate, a conveyer to convey said reduced-iron agglomerate is installed at the outlet of said reduced-iron agglomerate production equipment, a plurality of spray nozzles are installed above, or above and below, said conveyer at intervals in the conveying direction of said reduced-iron agglomerate, and said reduced-iron agglomerate on said conveyer is cooled intermittently by ejecting cooling water, continuously or intermittently, through said spray nozzles.
