摘　　要：为了降低烟化炉渣中的含锌量,分析了某烟化炉渣含锌高的原因。探究了鼓风炉渣型、一、二次风的比例、烟化炉吹炼时间对渣含锌的影响,确定了最佳鼓风炉渣型,吹炼时间及一二次风比。结果表明,控制CaO/SiO_2为0.9~1.2、吹炼时间为100~120 min、一二次风比为0.73~0.79,渣含锌可降至3%以下。This article analyzes the reasons of high zinc content of fuming furnace slag in order to reduce the zinc content in it. Explores the influence of blast furnace slag, the ratio of one and secondary air, and fuming furnace blowing time on zinc content of fuming furnace slag, determine the best type of blast furnace slag, blowing time and the ratio of one and secondary air. The results show that under the conditions of the ratio of CaO and SiO2 0. 9 1.2, blowing time of 100- 120 min, and the ratio of one and secondary air 0. 73- 0. 79 ,the zinc content of fuming furnace slag can be below 3%.
