    • As a pretreatment of a manufacturing process of sintered ore, a sintering material including iron ore, a SiO2-containing material, a limestone base powdery material and a solid fuel type powdery material is projected as a additional coating auxiliary raw material into the drum mixer with a additional coating conveyor disposed in proximity to an exhaust outlet of the drum mixer. Preferably, a sintering material excepting a limestone base powdery material and a solid fuel type powdery material is charged from a charge inlet of the drum mixer to granulate and in a region disposed on a downstream side, an additional coating auxiliary raw material including a limestone base powdery material and a solid fuel type powdery material is added, and thereby until reaching the exhaust outlet, the additional coating auxiliary raw material is deposited and formed on a exterior coating portion of the sintering material.

    • A simple and economical manufacturing method of a sintering material for manufacturing a sintering material suitable for manufacturing sintered ore excellent in the reducibility and high in the cold strength, and an apparatus therefor are proposed. As a pretreatment of a manufacturing process of sintered ore for use in a blast furnace by use of a Dwight-Lloyd type sintering machine of downward suction, a sintering material including iron ore, a SiO2-containing material, a limestone base powdery material and a solid fuel type powdery material is projected as a additional coating auxiliary raw material into the drum mixer with a additional coating conveyor disposed in proximity to an exhaust outlet of the drum mixer. Preferably, a sintering material excepting a limestone base powdery material and a solid fuel type powdery material is charged from a charge inlet of the drum mixer to granulate and in a region disposed in the middle on a downstream side where a staying time during which the sintering material reaches an exhaust outlet of the drum mixer is in the range of from 10 to 90 seconds, a additional coating auxiliary raw material including a limestone base powdery material and a solid fuel type powdery material is added, and thereby until reaching the exhaust outlet, the additional coating auxiliary raw material is deposited and formed on a exterior coating portion of the sintering material.
    • 提出了一种用于制造适合于制造具有优异的还原性和高的冷却强度的烧结矿的烧结材料的烧结材料的简单且经济的制造方法及其装置。 作为用于高炉的烧结矿的制造方法的预处理,使用德怀特 - 劳埃德式的向下吸入式烧结机,可以使用包含铁矿石,含SiO 2的材料,石灰石基础粉末材料和 将固体燃料型粉末材料作为另外的涂层辅助原料投影到鼓式混合器中,附加涂层输送器设置在鼓式混合器的排气出口附近。 优选地,除了石灰石基础粉末材料和固体燃料型粉末材料之外的烧结材料从鼓式混合机的充电入口装入颗粒,并且在设置在中间的区域中,在下游侧具有烧结 材料到达鼓式搅拌机的排气出口在10〜90秒的范围内,添加包括石灰石粉末材料和固体燃料型粉末材料的附加涂层辅助原料,从而直到到达排气出口, 附加的涂层辅助原料沉积并形成在烧结材料的外涂层部分上。
