Welding agent and welding method for welding anode steel claw

Abstract

The invention relates to a welding agent and a welding method for welding an anode steel claw. The welding method comprises the following steps of preparing the welding agent by mixing aluminum powder, magnesium powder, iron powder, titanium powder, copper oxide and silver powder with certain fineness according to a certain proportion, and then welding the anode steel claw by utilizing the welding agent; during welding, arranging a U-shaped metallic sheath between a steel-claw connecting rod and a steel-claw leg, then filling the welding agent in the gap of the U-shaped metallic sheath, igniting the welding agent, and welding the steel-claw connecting rod, the U-shaped metallic sheath and the steel-claw leg by utilizing high temperature generated by the welding agent. Compared with the prior art, only the damaged steel-claw leg needs to be excised, and then the undamaged steel-claw leg is welded onto the undamaged steel-claw connecting rod, so that a large amount of materials and working procedures are saved, and the production cost is greatly lowered; meanwhile, because the welding agent is used by the invention for respectively welding the U-shaped metallic sheath as a medium with the steel-claw leg and the steel-claw connecting rod, the welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to an anode steel claw used in the field of electrolytic aluminum, in particular to a flux for welding an anode steel claw and a welding method. Background technique [0002] When electrolyzing aluminum, it is necessary to use the anode steel claw to grab the carbon block as an anode and put it into the electrolytic cell for electrolysis. The anode steel claw is composed of a steel claw connecting rod and a steel claw leg that grabs the carbon block under the steel claw connecting rod. In the prior art, due to the erosion and erosion of the electrolyte, the steel claw legs are lost, which will make the steel claw legs not well connected with the carbon block, and the steel claws need to be replaced at this time. Since the steel claw connecting rod is not damaged, if only the steel claw needs to be replaced as a whole due to the damage of the steel claw leg, it will not only cause waste of casting materials for the steel claw conne...
