一、序言在对钢管、钢板、铁丝、铁板等材料进行热镀锌防腐、防锈处理时,常产出高锌渣。仅我省为此产出的锌渣每年有2000余吨。目前省内还没有一个较具规模的工厂来处理这种渣,虽有少数企业用蒸馏法(非横罐、竖罐)回收其中的锌,因其处理量小、回收率低、能耗大、劳动条件差、经济效益不高。为克服上述蒸馏法的缺点,1982年我所探索出了一种简易的、从热镀锌渣中回收锌的新方法。此法与蒸馏法比较,投资少、工艺简单、
First, the preamble In the steel pipe, steel, wire, iron and other materials for hot galvanized anti-corrosion, anti-rust treatment, often high output of zinc dross. Only our province for this output of dross each year more than 2,000 tons. At present, there is not a large-scale factory in the province to deal with this kind of slag. Although a small number of enterprises use the distillation method (non-horizontal tank and vertical tank) to recover the zinc therein, because of its small treatment capacity, low recovery rate and large energy consumption , Poor working conditions, low economic benefits. In order to overcome the shortcomings of the above distillation method, in 1982 I explored a simple, new method for recovering zinc from hot dip galvanized slag. This method is compared with the distillation method, less investment, simple process,
