Copper clad stainless steel plate includes a composite copper-clad stainless steel plate obtained by compounding a stainless steel cladding (1) and a copper conductive core row (4) by cold extrusion, and the copper conductive core row part exposed the stainless steel cladding is a conductive end face ( 5), the gap between the stainless steel cladding and the conductive end surface is welded together by nickel-copper welding wire, and the conductive end surfaces (5) of both ends of the composite copper clad stainless steel plate are welded to the stainless steel plug layer (2) by the stainless steel welding wire, the utility The new type can protect the conductive performance and extend the service life of the copper clad stainless steel plate, which not only makes it firmly combined with the stainless steel cladding, but also can well prevent the copper clad stainless steel plate from being electrolyzed during the electrolysis process. Stainless steel tubes form micro-batteries, cause corrosion of copper-clad stainless steel plates, voltage instability during electrolytic copper, and increased power consumption.
The beneficial effect of the utility model is that the copper clad stainless steel plate can be effectively protected to the maximum extent during the copper electrolysis process, preventing the corrosion of the copper-clad stainless steel plate by the electrolyte, increasing the service life of the cathode plate, and reducing the production process of copper electrolysis Unnecessary costs incurred. At the same time, the conductive performance of the electrolytic copper cathode plate can also be guaranteed to be greater than that of the original cathode plate during use, and the protection of the conductive performance of the copper clad stainless steel plate is the greatest beneficial effect of the present invention.

The improved copper clad stainless steel plate proposed by the utility model includes a stainless steel cladding 1 and a copper conductive core row 4. The stainless steel cladding and the copper conductive core row 4 are combined by cold extrusion to obtain a composite copper-clad stainless steel plate. A copper conductive row core 4 is milled out from the contact portion between the two ends of the stainless steel plate and the conductive row, and the copper conductive row core portion exposed to the stainless steel cladding is the conductive end surface 5. On both sides of the composite copper clad stainless steel plate, the copper conductive core and the stainless steel cladding are tightly welded together by nickel-copper welding wire with argon arc welding, and the gap between the stainless steel cladding and the copper clad stainless steel plate is welded after drawing. Fully and effectively protect the joint between the stainless steel cladding and the copper clad stainless steel plate from being corroded by the electrolyte to ensure the maximum conductivity of the copper clad stainless steel plate in electrolysis. A stainless steel plug layer 2 is welded to the conductive end surfaces 5 at both ends of the composite conductive copper beam for sealing treatment, and stainless steel welding wires are used for welding during sealing.
In the improved copper clad stainless steel plate proposed by the utility model, the welding seam 3 should be polished after welding to make it smooth and smooth without gaps, so as to ensure the maximum conductive performance and service life of the copper clad stainless steel plate in use. When the stainless steel cathode plate is used, if the copper clad stainless steel plate conductive end does not undergo the above treatment, the corrosion resistance of the cathode plate will be greatly reduced, and it will be a certain loss for daily production and company costs. If the cathode plate conductive end After the technical treatment of the utility model, due to the tight welding and the material itself has a certain corrosion resistance, it can well solve the series of unstable conductivity of the conductive end of the cathode plate due to long-term use problem.
