Abstract
A making process of durable stainless steel cathode plate for copper electrolyzing refining belongs to the field of non-ferrous metal smelting and metal surface treatment. The said cathode plate is made of 1Cr18Ni9Ti stainless steel, the surface has complete oxide film formed by the chemical oxidation or electrolysis oxidation and the edge of covered with engineering ABS plastics. The surface oxide film makes the cathode copper possess enough ahdesion to stainless steel and also be easy to be stripped, and can improve the cathode quality and raise the quality of cathode copper and the current efficiency. The use of the stainless steel cathode plate has no need of making the traditional titanium plate as initial electrode, and the cathode plate may be used repeatedly.
