Abstract

The invention relates to the field of production of large prebaked electrolytic cells, in particular to a repair method suitable for deformation of an anode guide rod hanging hole. Comprising the steps that a deformed sheath at a lifting hole of the deformed guide rod is dismantled, a new sheath is placed in the lifting hole of the deformed guide rod, a gap between the new sheath and the lifting hole of the deformed guide rod is subjected to repair welding through a self-propagating welding method, and the two ends of a welding face are polished to be smooth; compared with the prior art in which a new technology combining steel sheath replacement with self-propagating welding is adopted, the problem that the guide rod lifting hole is deformed and scrapped can be effectively solved, the maintenance and replacement cost of the anode guide rod is greatly saved, and a shortcut is found for reducing the production cost of electrolytic aluminum enterprises.

Description

technical field [0001] The invention relates to the production field of large-scale pre-baked electrolytic cells, in particular to a repairing method suitable for the deformation of an anode guide rod hanging hole. Background technique [0002] After long-term continuous use of the anode guide rod of the large-scale pre-baked electrolytic cell, the steel inner sheath of the lifting hole of the guide rod is subjected to the pulling force, and the deformation leads to the deformation of the lifting hole, resulting in the deviation of the center distance of the lifting hole of the guide rod, which affects the assembly of the anode. Production, it will have an impact on the cleaning of the residual electrode, the pressure stripping, the pouring of the new anode and the adjustment of the electrode distance during the electrolysis production process. Domestic electrolytic aluminum enterprises do not have a good repair method for the lifting hole of the aluminum guide rod. Usually,...
