摘　　要：电解槽打击头上粘的“壳头包”对电解槽的正常生产产生危害,打击头进入电解槽熔体的深度过深是产生壳头包的主要原因之一。电解铝厂打壳气缸和锤头安装使用后,锤头打击进入电解槽内的深度可以确定,但电解槽熔体的总高度是变化的,熔体总高偏高时,打击头进入熔体深度增加。针对上述缺陷,设计了一种具有可升降气缸的装置,该装置采用螺旋丝杠原理,通过操作螺旋丝杠来调节打击头打击的合适深度,不仅减少壳头包的产生,而且能延长锤头的使用寿命。The“accretion”stuck on the hammer of electrolytic cell is harmful to the normal production of electrolytic cell,and the deep intrusion of hammer into the melt of electrolytic cell is one of the main rea-sons for the formation of accretion.Once the crust-breaking cylinder and the hammer are installed and put into operation in an electrolytic aluminum plant,the intrusion depth of hammer into electrolytic cell is fixed,but the total height of electrolytic cell melt changes.When the total height of melt is high,the in-trusion depth of hammer into melt increases.In view of the above defects,a device with liftable cylinder is designed.Following the principle of screw,the proper striking depth of the hammer can be adjusted by operating the screw,which not only reduces the generation of accretion,but also prolongs the service life of the hammer.
