摘    要：通过对烧结配矿优选试验,不同R、SiO₂和MgO含量试验,不同的石灰石粉粒度试验结果的研究分析,提出了在高配比褐铁矿条件下适宜的配矿方案及合理的工艺参数。试验结果表明:石灰石粉粒度对烧结指标的影响较大。减少石灰石粉中<1 mm部分的比例,可使烧结生产率显著提高,烧结矿转鼓强度改善,固体燃耗降低。

Abstract: The suitable process parameters with high ratio of limonite were put forward through studying optimization of ore blending,different basicity,silica and MgO content of sinter,different size of limestone.The experiment results show that size of limestone has a great influence on sinter indices.When <1 mm of limestone is reduced,not only productivity is improved,but also TI of sinter is reformed and fuel consumption is reduced.
