细铝灰用于铝电解槽保温料的再利用试验
|
摘要
试验研究了用电解铝铸造过程中产生的细铝灰,作为电解槽生产的阳极保温料,以达到再利用细铝灰目的。试验持续三个月,此期间电解槽炉底压降增幅约10m V;原铝中铁含量与非试验槽基本持平,硅含量较非试验槽涨幅约0.005%,对电解生产和原铝质量影响很小。通过试验可知,此方法操作简便,对于铝灰回收具有可行性。
In this paper,the fine aluminum ash produced in the aluminum casting process was investigate as heat preservation materials for carbon blocks to reutilize. The test lasted for three months and the results revealed that the voltage drop of pot bottom increased by 10%,the silicon content in primary aluminum increased by 0. 005% and the iron content kept stable comparing with blank test pots,and it was feasible to reutilize aluminum ash as heat preservation material with advantages of handy operation and less effect on production and primary aluminum.
