近几年,随着大型预焙电解槽的推广使用,我国的铝电解技术和装备水平上了一个新台阶。但大型预焙铝电解槽的槽寿命较短,尤其是炉帮不稳固引起的侧部破损较多,严重影响和干扰了正常的铝电解生产,甚至漏槽造成阴极母线被冲断和电解槽停槽,使电解铝厂蒙受较大的损失,故大型预焙电解 In recent years, with the popularization and application of large prebaked electrolysis cells, the level of aluminum electrolysis technology and equipment in China has reached a new level. However, the slot life of large prebaked aluminum electrolysis cell is short, especially the side damage caused by the instability of the furnace is more serious, which seriously affects and interferes with the normal aluminum electrolysis production, and even the drain busbar causes the cathode busbar to be broken and the electrolytic cell Stop slot, the electrolytic aluminum plant suffered a greater loss, so large-scale prebake electrolysis
