摘　　要：针对传统的烧结—鼓风炉还原工艺生产流程长、能耗高、返料量大、SO2利用率低、铅蒸气和铅粉尘污染环境、劳动条件差等问题,世界各国开展了大量研究。按照实现强化作业的技术手段可分为闪速熔炼和熔池熔炼两大类,奥斯麦特属于典型的熔池熔炼。为加深对奥斯麦特炼铅工艺基本原理的理解,从原料入手,分析了渣型控制、分解过程、氧化熔炼过程和还原过程,找出了理论上的合理渣型要求和操作要点。In view of the traditional sintering blast furnace reduction process with long production process,high energy consumption,large amount of returned materials,low utilization rate of SO2,environmental pollution caused by lead vapor and lead dust,and poor working conditions,a lot of research has been carried out around the world.According to the technical means of strengthening operation,it can be divided into flash smelting and molten pool smelting.Osmat is a typical molten pool smelting.In order to deepen the understanding of the basic principle of osmat lead smelting process,starting from raw materials,the slag control,decomposition process,oxidation smelting process and reduction process are analyzed,and the reasonable slag type requirements and operation points in theory are found out.
