粒状金属铁的制造装置和粒状金属铁的制造方法
摘要：
一种将含有含氧化铁物质和碳质还原剂的混合物作为原料的压块，装入到移动炉床式加热炉的炉床上进行加热，还原该压块中的氧化铁而制造粒状金属铁的装置，该装置除了所述移动炉床式加热炉以外，还具备分级机、第一磁选机和第二磁选机，且具备如下路径：将所述来自移动炉床式加热炉的排出物向所述分级机供给的路径；将所述分级机分出的粗粒向所述第一磁选机供给的路径；和将所述分级机分出的细粒向所述第二磁选机供给的路径。
摘要（英）：

A device for producing granular metal iron by placing a mass of a raw material mixture comprises a substance containing iron oxide and a carbonaceous reducing agent on a heath of a moving heath type heating furnace and heating the mass to reduce iron oxide in the mass, thereby producing the granular metal iron. The device comprises, in addition to the moving heath type heating furnace, a sieving machine, a first magnetic separator and a second magnetic separator, and also comprises a passage through which a discharged substance from the moving heath type heating furnace is supplied to the sieving machine, a passage through which crude granules that have been sieved by the sieving machine are supplied to the first magnetic separator, and a passage through which fine granules that have been sieved by the sieving machine are supplied to the second magnetic separator.
