Stainless steel cathode material conducting structure for copper, nickel electrolytic refining or electrodeposition

A copper and nickel electrolyte refine or electric power stainless steel cathodic material conductive structure which is composed of the solid copper bar and the stainless steel cathodic material is provide. The structure of the utility model is characterized in that: as the load supporting beam, the square solid copper bar surface is connected with a stainless steel pipe of 2-3 mm thick to form a copper steel composition conductive bar where a groove of 3 micron meters wide and 2.5-3.5 mm deep is milled, wherein a stainless steel plate is inserted in the groove and welded together in the argon arc manner; the two ends of the copper steel composition current conducting rod are milled a platform of 60-100 mm long and 15-20 mm wide; the utility model uses the solid square copper bar as the load supporting beam with the composite stainless steel pipe arranged outside, which has a good welding performance with the stainless steel, and the conducting bar which has large conductive cross section can be operated under relatively large current density condition.
