工业纯镍由于具有很高的强度,良好的耐腐蚀性和工艺性能、因而在国内一些老的化工企业设备改造中,引起人们的重视。但是,由于镍的成本较高,又由于受冶炼条件的限制,不能轧制出较厚的大块板材。所以,在制造大型化工设备时都采用钢制外壳,里面衬一层纯镍衬里的结构形式。这样既可满足耐腐蚀性能,又能降低成本,因而得到了广泛的应用。 Industrial pure nickel due to its high strength, good corrosion resistance and process performance, which in some domestic old chemical equipment transformation, aroused people’s attention. However, due to the high cost of nickel and the limited smelting conditions, it is not possible to roll out thick, bulky plates. Therefore, in the manufacture of large-scale chemical equipment are used steel shell, which is lined with a layer of pure nickel lining structure. This will not only meet the corrosion resistance, but also reduce costs, which has been widely used.
