Abstract

An apparatus for manufacturing compacted iron for manufacturing reduced materials containing fine reduced iron into compacted iron and an apparatus for manufacturing molten iron provided with the sameare provided. The apparatus for manufacturing compacted iron includes i) a charging hopper into which reduced materials containing fine reduced iron are charged, and ii) a pair of rollers that form agap therebetween by being spaced apart from each other and that press the reduced materials containing fine reduced iron that are discharged from the charging hopper and pass through the gap, therebymanufacturing the compacted iron. The above-described charging hopper includes i) a surface of a wall, and ii) an integrated lower surface that is connected to the surface of the wall and is directedtoward the pair of rollers. In addition, at least one discharging opening is formed on the integrated lower surface to discharge the reduced materials containing fine reduced iron to the pair of rollers.

Description

technical field

[0001] The present invention relates to an apparatus for manufacturing compacted iron and an apparatus for manufacturing molten iron using the apparatus, and more particularly, the present invention relates to a reduced material containing direct reduced iron by compacting An apparatus for manufacturing compressed iron and an apparatus for manufacturing molten iron using the apparatus. Background technique

[0002] Currently, about 60% of the world's iron production is produced using the blast furnace method developed since the 14th century. According to the blast furnace method, iron ore that has undergone a sintering process is charged into a blast furnace together with coke produced using soot as a raw material, and oxygen is supplied to the blast furnace to reduce the iron ore to iron to produce molten iron.

[0003] The blast furnace method, which is most common in plants for manufacturing molten iron, requires raw materials to have at least a predeterm...
