精料是高炉强化的基础.精料的内容可以概括为“高、稳、熟、小、匀、净”六个字.提高含铁品位是增产节焦的前提,也是精料的基础.要获得成分稳定、品位高、氧化亚铁低、强度好、粒度均匀、粉末少的优质烧结矿和球团矿,除了对造块过程本身进行精心的操作和严密的控制外,还必须采取一系列措施:如注意铁矿的细磨深选;加强原料时混匀中和;进行烧结矿的整粒;降低燃料用量以及生产高碱度烧结矿和低碱度球团矿搭配使用等都是行之有效的方法.另一方面,造块设备的大型化和生产过程的自动控制和调节,不仅节省人力而且为产品的优质高产提供了可靠的手段.
Concentrate is the basis of blast furnace fortification. The content of concentrate can be summarized as “high, stable, cooked, small, uniform, net ” to improve iron content is the premise of increasing the production of coke, but also the basis of fine material In order to obtain high quality sintered ore and pellets with stable composition, high grade, low ferrous oxide, good strength, uniform grain size and little powder, besides the meticulous operation and strict control over the process of making block, it must also be taken A series of measures such as careful grinding of iron ore, deep mixing of iron ore, mixing and neutralization of raw materials, whole grain sinter, reduction of fuel consumption, collocation of high alkalinity sinter and low alkalinity pellets Is an effective way.On the other hand, large-scale production equipment and the production process of automatic control and regulation, not only save manpower but also provide a reliable means of high-quality products.
