摘　　要：影响锌锭品质的因素包括化学成分和物理外观。某锌冶炼厂针对锌锭品质问题,从锌电解原理及各道工序入手分析镉、铜、铅、铁等化学成分的影响因素及控制措施,从锌锭熔铸过程的各个细节操作控制物理外观质量,采取相应措施后,取得了0;锌产出率100%、废锭率小于1%的效果,最高锌锭品质达到99.997%以上,获得了良好的经济效益。The factors that influence zinc ingot quality include chemical composition and physical appearance. To tackle the low quality of zinc ingots produced from a zinc refinery, analysis has been made on the influence factors and control measures of chemical compositions such as Cd, Cu, Pb and Fe, from the perspective of zinc electrolysis principle and the various electrolysis procedures, and measures has been taken to control the physical appearance quality of zinc ingots in every detail of zinc ingot casting operation. As a result, the yield of 0;zinc reaches 100%, the scrap percentage is lowered to less than 1% and the highest quality of zinc ingots reaches 99.997% or more, whereby good economic benefits are achieved.
