通过对新疆菱铁矿的烧结试验研究得出:新疆菱铁矿铁品位较低,CaO质量分数超高,达到7.87%,SiO2质量分数很低,只有0.79%。因此以新疆菱铁矿为主要原料进行烧结,为达到高炉生产所需要的碱度,就需配加适量的硅石或含SiO2较高的矿粉。烧结矿燃料配比为5.2%～5.6%,转鼓指数可达到56%～57%,可用于中、小高炉冶炼。 Through the sintering test of siderite in Xinjiang, it is concluded that Xinjiang siderite has a low grade of iron, high CaO content of 7.87%, and low SiO2 content of 0.79%. Therefore, siderite in Xinjiang as the main raw material for sintering, in order to achieve the necessary alkalinity for blast furnace production, it is necessary to add the right amount of silica or SiO2-containing ore powder. Sinter fuel ratio of 5.2% to 5.6%, drum index can reach 56% to 57%, can be used for medium and small blast furnace smelting.
