Effect of leveling method on elastic modulus of stainless steel substrate  of electrolytic copper

Abstract

Abstract: During the electrolytic refining of copper, the stainless steel substrate is used as a permanent cathode, and the flatness of the substrate has an important influence on the efficiency and energy consumption of electrolytic copper. In the large-scale production of electrolytic copper stainless steel cathode plates, the influence of the cathode plate leveling method on the elastic modulus of the substrate was studied. The elastic modulus of the 316L stainless steel substrate was measured using the deflection method, and the influence of different leveling times and directions on the elastic modulus of the 316L stainless steel substrate was explored. The results showed that when leveling in one direction, the elastic modulus of the stainless steel substrate gradually decreases with the increase of the leveling times. When leveling in the longitudinal and transverse directions, the elastic modulus also shows a downward trend, with a more pronounced reduction observed in the longitudinal direction.

Key words: stainless steel substrate, leveling, deflection method measurement, elastic modulus
