Title:
MATERIAL PROCESSING FACILITY AND MATERIAL PROCESSING METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/086534
Kind Code:
A1
Abstract:
A material processing facility according to the present invention comprises: a plurality of carriages, each of which has first and second granules charged therein, the first granules being materials for producing reduced iron and the second granules being materials for producing sintered ore and being located on the first granules, wherein the carriages are able to move to a material processing section that includes a sintering section for sintering the second granules and a reduction section for reducing the first granules, the reduction section being located behind the sintering section; an ignition furnace installed on a path along which the plurality of carriages move to the material processing section and directing flames toward the surface layer of the second granules; a plurality of wind boxes arranged below the plurality of carriages in the direction in which the plurality of carriages move and providing an attractive force to each of the plurality of carriages; and an atmosphere producing unit located in the reduction section and having a circulation line for collecting a reduction exhaust gas caused by a reduction reaction from a carriage in which the first granules are being reduced and supplying the reduction exhaust gas to a carriage located in the reduction section. Accordingly, in accordance with embodiments of the present invention, it is possible to produce sintered ore and reduced iron together using the material processing facility in which the plurality of movable carriages sequentially move to process material. That is, in the material processing facility in which the movable carriages move, it is possible to produce sintered ore and reduced iron together using the same facility by making a predetermined section an atmosphere in which sintering is easy to carry out and making another predetermined section an atmosphere in which reduction is easy to carry out.
