Research and Test Analysis on the Leveling Scheme of Nickel Starting Sheet
During the production of electrolytic nickel,the sagging degree of the nickel starting sheet will affect the quality of the electrolytic nickel product.The paper analyzes the cause of poor sagging degree in the production of nickel starting sheet,puts forward a leveling scheme of"straightening and pressing by rollers",which improves the flatness of the plate by eliminating internal stress,increasing the rigidity of the plate and overcoming the rebound of the plate through the process of rough straightening,then fine straightening and finally roll pressing.The test results show that the nickel starting sheet after leveling and roll pressing has significantly improved in appearance,and the thicker the nickel starting sheet is,the better the leveling effect is.Appropriate longitudinal pressing is beneficial for overcoming the longitudinal curling of the starting sheet.Therefore,the feasibility of the leveling scheme can be confirmed.
