电流效率分析仪在电解槽上的应用

Application of the current efficiency analyzer on aluminium smelting pots

介绍了一种电流效率分析仪在400kA铝电解槽上的实测情况。近年来低电压生产是铝电解生产一个热门的技术思路,现在国内最低运行电压已达到3.8V,但是最终的槽电压是多少才能取得最佳的经济指标,还没有一个公认的数据,这与目前缺乏实时、准确的电流效率测试仪器有关。中孚铝业在2009年引进了一台电流效率分析仪,并在400kA铝电解槽上进行了相关测试,各项测试结果表明该仪器的稳定性达到了预想效果。

This paper discusses the application of a current efficiency analyzer which can be use to analyse current efficiency of 400kA aluminium smelting potline.In recent years,low voltage operation has become a popular topic in aluminium smelting field.At the moment the lowest operating voltage has achieved as low as 3.8V in China.However,the lowest voltage target which is optimal and more economical has not been found and commonly agreed.This is partly because of the lack of equipment to measure current efficienc...
