Background
The anode guide rod of the large-scale prebaked electrolytic cell is continuously used for a long time, and the steel inner sheath at the hanging hole part of the guide rod is deformed under the action of pull-up force, so that the hanging hole is deformed, the center distance of the hanging hole of the guide rod is deviated, the assembly production of the anode is influenced, and the anode guide rod can influence the cleaning and pressing-off of anode scraps, the pouring of a new anode and the adjustment of the pole distance in the electrolytic production process. The domestic electrolytic aluminum enterprises have no better repairing method for the aluminum guide rod lifting hole, and generally, the deformed guide rod is withdrawn from operation in a guide rod scrapping mode after the deformation of the anode lifting hole reaches 5mm, and a new guide rod is used for threading again, so that the cost control of the electrolytic aluminum enterprises is greatly influenced.
Thus, there remains a need in the art for improvements.
