摘　　要：本文以我公司400KA大型铝电解槽焦粒焙烧及无效应启动实践为基础,分析总结了400KA大型预焙铝电解槽在焦粒焙烧及启动中各环节关键点的控制要点和操作注意事项,对各环节不同的操作方式进行了分析对比,以期对占我国电解铝产能较大份额的400KA铝电解槽系列的焦粒焙烧和启动方式方法起到借鉴作用,避免在焙烧启动阶段出现影响系列安全的异常现象。Based on the practice of coke grain roasting and non effect starting in 400KA large aluminum electrolysis tank of our company,this paper analyzes the operation points for the key points of 400KA large prebaked aluminum electrolysis and analyses and compares the different operating modes of each link in order to make up for me.The coke-particle roasting and starting method of a series of 400KA aluminum electrolysis cell series in the country's electrolytic aluminum production have been used for reference,avoiding the abnormal phenomena that affect the series safety during the roasting start stage.
