摘要

针对目前铝电解槽阳极电流在线测试方法的不足

基于铝电解槽电磁场的理论

借鉴国外学者通过测试导杆附近的磁场来得到阳极电流的思想

提出了一种阳极电流非接触式测试方法

并着重针对铝电解槽不同的进电方式分析了阳极电流的测量误差

并对误差进行了修正

对测试方案进行了优化

旨在实现阳极电流的实时监测和在线控制。研究结果表明

300 kA大面五点进电槽的阳极电流测量误差可以控制在±0.25%之内

而400 kA大面六点进电槽、200 kA大面四点进电槽的阳极电流测量误差分别达到了±0.8%和±3%;可见不同进电方式对阳极电流的测量误差有较为明显的影响

但最大误差均不超过3%。因此

对于不同进电方式及结构的铝电解槽阳极电流的在线监测

该非接触式测试方法均具有较好的适用性。

Abstract

By referring to the measurement principle of individual anode current through obtaining the magnetic field near the anode

a new non-contact measurement of individual anode currents based on the principle of electromagnetic field

was developed.The error distribution of the anode current on various current risers in aluminum reduction cell was analyzed and the measurement method was optimized to realize anode current real time monitoring and on-line control.The relative errors of anode current in 300 kA cell were within ±0.25%

but the relative errors of anode current in 400 kA and 200 kA cells were ±0.8% and ±3% respectively.Current risers had an influence on the relative errors of anode current

but the maximal error was within 3%.Therefore

the non-contact measurement was applicable to online monitoring of individual anode current with different current risers and structures in aluminum reduction cell.
