AI Technical Summary
Existing copper-aluminum composite plate rolling equipment has a high deformation rate of the upper copper layer during the production process, making it difficult to produce copper-aluminum composite plates with an ultra-thick copper layer ratio.
A design with an upper roll diameter larger than the lower roll diameter is adopted, combined with an appropriate diameter ratio (1.02-1.5 times) to reduce copper layer deformation and increase the copper layer ratio.
By reducing copper layer deformation, the production of copper-aluminum composite plates with an ultra-thick copper layer ratio was achieved, thus reducing the deformation rate of the copper layer.
