电解系列停限电后严重冷行程的不停槽处理

Treatment of severely cold reduction cells after a long time failure of power

本文阐述了大型预焙槽系列超长时间停限电后，在电解槽电解质全部凝固于槽底、槽温降至700℃～800℃的超低温状态下。采用一系列特殊方法。对系列电解槽成功启动恢复生产，未发生一台槽停槽、漏槽，为国内电解铝厂处理类似事故总结了经验。探索出一条可行的道路。

The paper presents a special way to restore operation of reduction cells in case that when power fails for a long time, all baths solidify on the bottom and temperature drops down to 700℃ -800℃, which has not one single stopped and leaked cell. It may be as a referance for the other plants.
