<p>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. <IMAGE></p> |
