Abstract

The invention relates to a repairing device for an anode steel claw which is a consumptive part in the field of electrolytic aluminium, belonging to the electrolytic aluminium industry. The invention has the technical scheme that in a device for repairing an electrolytic aluminium anode steel claw by total cross-section fusion welding, a slag pool is formed by metal pallets and a cavity formed by moulds and a residual steel claw leg; the metal pallets are respectively arranged at the two opposite sides of the residual steel claw leg; the moulds are respectively positioned on the metal pallets and are closely jointed with the residual steel claw leg; the upper part and the lower part of each mould are respectively connected with a water outlet pipe and a water inlet pipe, and the interiors of the moulds are cavities; fluxing agent is arranged in the slag pool; an electrode is inserted into the slag pool, and a certain distance is maintained between the electrode and the residual steel claw leg; and the electrode and the residual steel claw leg are connected with a transformer by leads. The steel claw leg repaired by the device is high in strength and utilization rate; and meanwhile, the energy is saved, the consumption is reduced, and the problems caused by artificial repairing can be solved.

Description

technical field [0001] The invention relates to a repairing device for anode steel claws of consumable parts in the electrolytic aluminum field, belonging to the electrolytic aluminum industry. Background technique [0002] The electrolytic aluminum anode steel claw is the connecting piece between the anode carbon block on the aluminum electrolysis equipment and the anode of the aluminum electrolysis circuit. During the aluminum electrolysis process, it carries a high-power current and is often eroded by the high-temperature electrolyte, resulting in The bit corrosion is serious, so after working for a period of time, the steel claw legs connected with the anode carbon block will gradually become thinner, resulting in increased resistance at the thinned parts of the steel claw legs, severe heat generation, and increased energy consumption, which in turn further The corrosion of the gradually thinning steel claw legs is accelerated, which affects the efficiency of electrolyti...
