一、铅锌密闭鼓风炉熔炼的优缺点在炼锌工业中,湿法炼锌近年在世界上发展很快,六十年代和七十年代新建了二十多家湿法电锌厂,而铅锌密闭鼓风炉在六十年代是发展得较快,但七十年代新建的不多,现国外生产的有十一台铅锌密闭鼓风炉(表1),约占总产锌量的12%左右。铅锌密闭鼓风炉的优 First, the advantages and disadvantages of smelting lead-zinc closed blast furnace In the zinc smelting industry, zinc hydrometallurgy developed rapidly in the world in recent years, more than 20 new wet-process zinc smelters were built in the 1960s and 1970s, while lead-zinc Sealed blast furnaces developed rapidly in the 1960s but not many newly built ones in the 1970s. Eleven lead-zinc enclosed blast furnaces (Table 1) are currently produced abroad, accounting for about 12% of the total zinc output. Lead-zinc sealed blast furnace’s excellent
