摘　　要：美国某闪速冶炼厂经过二十多年的生产,很多设施已开始老化。随着铜精矿铜硫比降低,闪速炉热负荷提升,同时精矿中铅、铋等含量变高,烟尘粘结性增加,锅炉易结大块,需要更频繁地清理烟道和锅炉。因此冶炼厂针对原料系统和熔炼系统进行了诊断,围绕分析影响熔炼作业率的原因,并提出了优化改造的方案,并对各建议进行了多因素的量化对比,以直观地对各建议的预期效果进行了预测与分析。After more than 20 years of production,many facilities in a flash smelter from America begin to aging. The copper-sulfur ratio of copper concentrates decreased and the thermal load of flash furnaces increased. Moreover, the content of lead and antimony in concentrates become higher, and soot adhesion of the dust is increased. Boilers tend to be bulky and the flue and boiler require more frequent cleaning. The smelter conducts a diagnosis on the concentrate and smelting system, and analyze the reason that affected the smelting operation rate, and proposed a plan for technical upgrade. Moreover, the researchers make a comparison of quantitative factors and show the effects on their plan.
