精料是炼铁生产的基础。高炉的原料,主要分人造富矿和天然富矿,二者根据加工工艺、产地和矿物结构的不同,又可分成很多种类。合理地选择配料方案,以实现高炉优质、高产、低耗,达到最佳的经济效益,是高炉工作者追求的目标之一。一、武钢历年来使用的几种主要矿石 1.烧结矿自1959年8月一烧车间投产后,即开始使用烧结矿,最初生产的低碱度烧结矿,碱度一般在1.0以下,粘结相中玻璃质和硅酸盐较高,FeO含量高,因之,还原性能差,转鼓指数低,很快就被自熔性烧结矿取代。武钢在1980年以前,主要是生产自熔性
Concentrate is the basis of iron production. Blast furnace raw materials, mainly composed of man-made rich ore and natural rich ore, both according to the processing technology, origin and mineral structure of different, can be divided into many types. Reasonable choice of ingredients in order to achieve high quality blast furnace, high yield, low consumption, to achieve the best economic benefits, is one of the goals pursued by blast furnace workers. First, Wuhan Iron and Steel over the years used several major ore 1. Sinter Since August 1959 a burning workshop put into operation, that is, began to use sinter, the initial production of low alkalinity sinter, alkalinity generally below 1.0, bonding Phase glass and silicate higher, high FeO content, therefore, the reduction of poor performance, low drum index, and soon replaced by self-fluxing sinter. Before 1980, WISCO mainly produced self-fluxing
