摘要： In production of sintered ore using an air suction type sintering process, a method and an apparatus for producing sintered ore by allowing sintering to progress under a state in which a magnetic levitation force is applied characterized in that the surface of a raw material layer is ignited, that after sintering has started at the upper layer portion of the raw material layer, a magnetic field is applied to the raw material by means of a magnetic levitation device that is not in contact with a sintered cake in which burning is completed so that a magnetic levitation force is applied thereto, and that while the magnetic levitation force is being applied, a magnetic levitation force acting in a widthwise direction which is normal to a sintered strand is distributed so that uniform sintering is achieved through uniform ventilation distribution. The method and apparatus are further characterized in that uniform sintering is achieved through continuous application of magnetic levitation force by means of a magnetic levitation device which can be moved while in contact with the sintered cake. The method and apparatus are still further characterized in that uniform sintering is achieved by applying magnetic levitation force mainly to portions of the sintered layer where ventilation is poor by means of a plurality of non-contact and movable magnetic levitation devices.
摘要翻译：在使用空气抽吸式烧结工艺生产烧结矿时，通过使烧结在使用磁悬浮力的状态下进行烧结的方法和装置，其特征在于，原料层的表面被点燃在原料层的上层部分开始烧结之后，通过与烧结完成的烧结块不接触的磁悬浮装置向原料施加磁场，使得施加磁悬浮力，并且在施加磁悬浮力的同时，沿着与烧结股线垂直的宽度方向作用的磁悬浮力被分布，使得通过均匀的通风分布实现均匀的烧结。该方法和装置的特征还在于，通过借助磁悬浮装置连续施加磁悬浮力来实现均匀烧结，磁悬浮装置可在与烧结块接触的同时移动。该方法和装置的特征还在于，通过利用多个非接触可移动磁悬浮装置将磁悬浮力主要施加在通风不良的烧结层的部分上，实现均匀烧结。

摘要： A method for sintering iron scraps used in a process for producing sintered ore serving as a raw material in iron making in a blast furnace or the like. Eliminating Zn in iron scraps during a sintering process makes it possible to use a large amount of light-weight iron scraps in a blast furnace and also to improve the yield in production of sintered ore during the sintering process. In producing sintered ore used as a raw material for blast furnacing with a Dwight Lloyd type sintering machine, a mixture obtained by mixing small iron scrap chips into a raw material for sintered ore is placed on a pallet to thereby produce scrap-containing sintered ore. In compounding into a loading layer, it is possible to select between three methods, compounding into all layers, compounding only into an upper layer, and compounding only into a lower layer. Iron scraps are fixed in sintered ore to serve as a raw material used in a blast furnace. Furthermore, with this method, the amount of coke used as a heat source can be reduced and generation of CO2 and NO2 by burnt coke can be restricted.
摘要翻译：一种用于烧结铁渣的方法，用于生产在高炉等中的铁制造中用作原料的烧结矿的方法。在烧结过程中，在铁屑中排除Zn使得可以在高炉中使用大量的轻质铁屑，并且还可以提高烧结过程中烧结矿的生产成品率。在用德怀特劳埃德式烧结机制造用作高炉的原料的烧结矿中，将小铁屑切碎成混合物的烧结矿石原料混合物放在托盘上，从而生产含废料的烧结矿石。在加入加载层中，可以在三种方法之间选择，复合到所有层中，仅混合到上层中，并且仅复合成下层。铁屑在烧结矿中固定，用作高炉中使用的原料。此外，通过该方法，可以减少用作热源的焦炭的量，并且可以限制由焦炭引起的CO 2和NO 2的产生。
