| 摘 要： | 首先对高炉使用双碱度烧结矿的优点进行了理论上的分析。通过实验室试验研究了自0.04至3.0的碱度对烧结矿生产和质量的影响。以缩短软熔温度区间为目标，优化了高炉炉料结构。研究结果证明，使用酸性烧结矿与碱性烧结矿为基础的配矿方案对减薄高炉软熔带厚度，改善料柱透气性具有明显作用。

| Abstract: | A research on sinter production and quality with different basicity from 0.04 to 3.0 were accomplished experimentally and theoretically. Burden structure including sinters with different basicity was optimized to reduce the thickness of cohesive zone in blast furnace. The results show that using acidic sinter combined with alkaline sinter is one of effective methodsto reduce the temperature range of cohesive zone and to improve the permeability of stock column in blast furnace. |
