APPARATUS FOR MANUFACTURING COMPACTED IRON, AND APPARATUS FOR MANUFACTURING MOLTEN IRON COMPRISING THE APPARATUS

摘要

The present invention relates to an apparatus for manufacturing compacted iron and an apparatus for manufacturing molten iron comprising the same. The apparatus for manufacturing compacted iron comprises: i) a roll core comprising a shaft; and ii) a roll tyre surrounding a circumference of the roll core and having a recess on a surface thereof applied such that compacted irons are manufactured by compressing powder to the compacted irons. A cooling passage through which a cooling fluid applied to cool the roll tyre flows is formed on border surfaces of the roll tyre and the roll core contacting each other, and at least one sealing groove located in parallel to the cooling passage and spaced apart from the cooling passage and applied to seal the border surfaces is formed on the border surfaces.
