1 概况密闭鼓风炉是英国帝国熔炼公司阿旺茅斯铅锌冶炼厂于1946年试验成功的,随后于1948年设计了日产粗锌25t的1~#炉。目前该厂4~#炉年产锌10×10~4t,铅4×10~4t,是世界上最大的密闭鼓风炉。密闭鼓风炉由于能够处理铅锌矿并同时分别产出铅、锌,因此在60年代曾得到了迅速发展。但进入70年代,由于焦炭价格上涨 1 Overview The closed blast furnace was successfully tested by the British Empire Smelting Company, Urawamg Lead-Zinc Smelter in 1946, followed by the design of a 1-ton furnace of crude zinc 25 t per day in 1948. At present, the plant 4 ~ # furnace annual production of zinc 10 × 10 ~ 4t, lead 4 × 10 ~ 4t, is the world’s largest sealed blast furnace. Sealed blast furnaces developed rapidly in the 1960s because they were capable of handling lead and zinc mines and simultaneously producing lead and zinc respectively. But into the 70s, due to the price of coke
