Abstract

The present invention relates to an apparatus for manufacturing compacted irons and an apparatus for manufacturing molten irons using the same. For this, the apparatus for manufacturing compacted irons according to the present invention includes a couple of rolls and a roll casing. The couple of rolls compress reduced materials containing fine reduced irons, manufacture the compacted irons, and form a gap by being separated from each other. The roll casing is located outside of the couple of rolls and has at least one opening. Sealing plates are attached to an inner surface and an outer surface at the opening of the roll casing, respectively. A sliding tube, both ends of which the sealing plates are fixedly combined with, is closely adhered to a penetrating member penetrating the opening. According to the above present invention, it is possible to manufacture compacted irons having good quality.
