Low-deformation and high-electrical-efficiency anode plate for zinc electrolysis and preparation method therefor

The invention discloses a low-deformation and high-electrical-efficiency anode plate for zinc electrolysis and a preparation method therefor. The preparation method comprises alloy smelting, continuous casting extrusion, plate shearing, punching, plate splicing and welding and beam welding, and the finished anode plate is obtained. In the continuous casting extrusion, molten lead alloy is guided into a wheel groove of a continuous extruding machine to be cast and extruded, and a lead plate strip with a groove is obtained; the plate shearing is that the lead plate strip with a groove is cut into a plurality of strips according to the length of the plate surface of the anode plate; the plate splicing and welding is to transversely splice and weld the cut lead plate strips with the grooves according to the plate surface width of the anode plate to obtain the anode plate. By means of continuous extrusion forming, composition segregation can be avoided, machining defects can be reduced, the anode plate machining p
