一、概述在现代有色金属湿法冶炼中,各种混凝土槽、塔、罐等是冶炼工艺的主要生产设备。生产过程中,由于酸、碱、盐等侵蚀性介质的作用,这些设备均腐蚀严重。某冶炼厂是年产16.5万吨的大型有色金属冶炼企业,除铜、铝采用火法粗炼外,全厂所有产品几乎均采用电解精炼,它具有大型化和连续化的特点。其中年产电解锌10万吨、电解铝5.5万吨、电解铜1万吨规模的三个分厂拥有混凝土电解槽(规格2.4×10×1.5米)1108个、容积1000米~8的浓缩槽10
First, an overview In the modern non-ferrous metal smelting, all kinds of concrete tanks, towers, cans and other smelting process is the main production equipment. The production process, due to acid, alkali, salt and other aggressive media, these devices are severely corroded. A smelter is an annual output of 165,000 tons of large non-ferrous metal smelting enterprises, in addition to copper, aluminum fire crude, all the products of the plant are almost all electrolytic refining, it has the characteristics of large-scale and continuous. One of the annual output of electrolytic zinc 100,000 tons, 55,000 tons of electrolytic aluminum, electrolytic copper scale of 10,000 tons of three plants with concrete electrolyzers (size 2.4 × 10 × 1.5 m) 1108, the volume of 1,000 m 8 enrichment tank 10
