摘　　要：对沉铁渣及其相关渣型物化性质进行了实验研究,确定了最优渣型,获得了最优工艺条件。结果表明,在钙硅比为0.75、不外加二氧化硅、熔炼温度1 250℃、反应时间1 h,沉铁渣与焦粉的重量比为2.8、渣料含水小于10%、渣料粒度控制在10~120目区间等优化工艺条件下,铅锌的平均挥发率分别为96.39%和97.06%。An experimental research was made on the physical and chemical properties of the heavy iron slag and its related slag. The optimal type of slag and the process conditions were defined. The results showed that the average evaporation rate of lead and zinc were 96.39% and97.06% respectively under the optimized conditions such as calcium-silicon ratio of 0.75, no addition of silica, melting temperature of 1250℃, reaction time of1 h, slag-coke weight ratio of2.8, moisture content less than 10% in slag and granularity of slag charge controlled within the range of 10 ~ 120 meshes.
