摘要
针对600 kA铝电解槽焙烧启动时存在角部阳极导电偏低、电流分流量低、冲击电压高、启动温度高、灌铝量低等问题,某公司从装炉作业、分流设计、焙烧升温制度、启动温度控制、灌铝前后电压控制等方面优化电解槽焙烧启动工艺,取得了良好的焙烧启动效果。
In view of the problems such as low conductivity of corner anode, low shunt volume of current, high impulse voltage, high start-up temperature and low aluminum pouring content during roasting start-up of 600 kA aluminum reduction cell, the roasting start-up process of the reduction cell was optimized from the aspects of charging operation, shunt design, roasting heating program, start-up temperature control, and voltage control before and after aluminum pouring in a company, and good roasting start-up effect was achieved.
