电炉炼锡同反射炉和回转炉炼锡相比较具有许多优点。虽然大型炼锡厂只是最近才采用,但几个小炼锡厂已采用电炉炼锡多年了。本文介绍了这些厂家所用电炉的不同型式。并讨论了它们的特征。如果设计正确,小型电炉可以是相当简单而廉价的。文中列出了重要的设计参数,同时介绍了典型埋弧式电炉的结构。如果有预处理作业,则可以熔炼范围广泛的原料。采用几座小电炉可使冶炼流程具有较大的灵活性。还讨论了冶金过程的各种因素以及一般的操作参数。文章给出了投资和生产费用的细节以证明采用小型电炉炼锡在经济上的利益。
Electric furnace smelting tin with refiring furnace and rotary kiln has many advantages. Although large-scale smelting tin only recently adopted, but a few small smelting tin smelting tin has been used for many years. This article describes the different types of electric furnaces used by these manufacturers. And discussed their characteristics. If designed correctly, small electric stoves can be fairly simple and inexpensive. The article lists important design parameters and describes the structure of a typical submerged arc furnace. With pretreatment operations, a wide range of feedstocks can be melted. Using a few small electric furnace smelting process can have greater flexibility. Various factors of the metallurgical process as well as general operating parameters are also discussed. The article gives details of investment and production costs to prove the economic benefits of using small EAF smelting tin.
