铝电解槽滚铝原因分析及预防措施

Cause Analysis and Preventive Measures of Aluminum Rolling in Aluminum Electrolytic Cell

滚铝对生产造成诸多不利影响,不但降低电解槽运行的稳定性,产生电流空耗,影响能耗指标,严重时可能导致停槽停电。本文详细介绍了铝电解槽发生滚铝时的表现,以及滚铝产生的根本原因和滚铝前兆特征,并根据电解生产过程中可能导致滚铝的5种常见原因进行了具体分析,针对性提出了相应的预防措施,最后给出了滚铝事故的处理建议,为铝电解生产预防滚铝发生和处理滚铝槽提供借鉴。

Rolling aluminum has many adverse effects on production including reducing the stability of the electrolytic cell,causing current drain which affects energy consumption indicators,and even cell shutdowns and blackouts in severe cases.This article introduced in detail the performance of aluminum electrolytic cells when aluminum rolling occurs,as well as the root causes and precursory characteristics of aluminum rolling.A specific analysis was carried out on the five common reasons that may cause aluminum rolling during the electrolytic production process,preventive measures targeted at each cases were put forward accordingly and recommendations for handling aluminum rolling were finally given to provide reference to prevent aluminum rolling and handle the cell with aluminum rolling occurrence during aluminum electrolysis.
