摘　　要：对比了三连炉工艺和氧气底吹-鼓风炉还原炼铅工艺的铅、铜、锌回收率,分析了三连炉工艺取消电热前床的合理性和可行性,同时考察了三连炉法CaO/SiO_2和Fe/SiO_2对终渣中Cu含量的影响。The recovery of lead, copper and zinc in lead smelting reduction process with tri-continuous furnace and oxygen bottom-blown-blast furnace were compared respectively, the reasonable and feasibility of removing the elec- tric heating fore-hearth in tri-continuous furnace process were analyzed, and the effects of CaO/SiO2 and Fe/SiO2 produced in tri-continuous furnace process on the Cu contents in final slag were investigated.
