    • The present invention relates to an apparatus for manufacturing molten iron. The present invention provides an apparatus for manufacturing molten iron including a charge container receiving the supply of reducing material in which hot fine direct reduced iron from multiple fluidized-bed reactors are mixed; at least one pair of roller presses to which the fine direct reduced iron is supplied to undergo roll pressing, thereby producing continuous compacted material having lumped portions adjacent to each other; a crusher crushing the compacted material produced by the roller presses; and a melter-gasifier to which is charged crushed compacted material that is crushed by the crusher. Each of the pair of roller presses include pressed portions and protruded lines formed between the pressed portions. The pressed portions include first and second pressed portions opposing each other and first and second concave surfaces continuously formed on the first and second pressed portions along an axial direction of the at least one pair of roller presses, respectively. When viewed from a direction perpendicular to a plane centered between the first and the second pressed portions: (i) the first and second concave surfaces partially overlap each other, and (ii) the protruded lines are unaligned on the opposing first and second pressed portions.
    • 本发明涉及一种用于制造铁水的设备。 本发明提供了一种用于制造铁水的装置,其包括:容纳来自多个流化床反应器的热精细直接还原铁混合的还原材料供应的加料容器; 至少一对辊压机,其中供给精细的直接还原铁以进行辊压,从而产生具有彼此相邻的集中部分的连续压实材料; 破碎机压碎由辊压机生产的压实材料; 以及熔化炉 - 气化器,被破碎机粉碎的带有粉碎的压实材料。 一对辊压机中的每一个包括压制部分和形成在压制部分之间的突出线。 按压部分包括彼此相对的第一和第二压制部分,以及沿着至少一对辊压机的轴向方向连续形成在第一和第二按压部分上的第一和第二凹面。 当从垂直于第一和第二按压部分中心的平面的方向观察时:(i)第一和第二凹面部分彼此重叠,并且(ii)突出线在对置的第一和第二按压部分 。

    • Disclosed is a swing relief energy regeneration apparatus in which working oil relieved into a hydraulic tank is stored in a pressure accumulator during swing and deceleration to recycle the stored pressure. The swing relief energy regeneration apparatus includes: a hydraulic pump and hydraulic motor; a swing motor connected to the hydraulic pump through first and second paths; a flow rate control valve controlling the working oil supplied from the hydraulic pump into the swing motor; a first passage having both ends branched and connected to the first and second paths to allow the working oil to move in one direction toward the first or second path from the hydraulic tank; a second passage defined parallel to the first passage and having both ends branched and connected to the upstream sides of the first and second paths to allow the working oil to move in one direction toward the hydraulic tank from the first or second path; a pressure accumulator disposed in a recycling path having one end connected to the second passage and the other end connected to the hydraulic motor to store the working oil relieved into the hydraulic tank; and a sluice valve opened to supply the working oil into the hydraulic motor from the pressure accumulator when the manipulation amount of a manipulation lever for controlling the operation of the excavator exceeds a set value.
