铝电解槽扩容后炉底压降上升的原因和预防措施

Causes for the rising of voltage drop at the bottom of the cell after increasing the amperage of cell and the precautions

通过对160kA预焙铝电解槽扩容改造前后炉底压降变化趋势的对比分析,发现160kA预焙铝电解槽扩容改造后炉底压降上升,针对这个问题,提出了一套简单易行的处理措施,供同行交流和参考。

After comparing the data of 160kA pre- baked anode cell with those of increased amperage one, the authors found out the rising of voltage drop at the bottom of the cell and some measures for it.
