摘　　要：在石钢目前的原料条件下,探索不同烧结矿配比的适宜碱度值。碱度拟定为1.8、2.1、2.4等3个梯度水平,在碱度变化过程中其它参数保持不变。实验结果表明,随碱度的增加,烧结矿软熔性能、烧结矿粒度及烧结矿低温还原粉化指标明显改善。当碱度在2.1时烧结矿综合指标最佳。In the condition of sinter mix materials used presently in Shijiazhuang iron and steel Co.,laboratory tests were conducted to search the suitable basicity of sinters.The basicity tested has three gradient levels of 1.8,2.1 and 2.4.The results show that sinter quality gets better with increase of basicity.As the rising of basicity,the softmelt property,the granularity of sinter and its anti-pulverization in low-temperature reduction are obviously improved.The complex index of sinter is the best at basicity of 2.1.
