摘要：The mismatch of lengthwise elongation due to the difference of deformation resistances between constituent materials of bimetallic slab can cause warping. As the warping of bimetallic slab can lead to poor product shape with reduced productivity, this study focuses on the effect of differential speed rolling on the reduction of warping. The effects of differential speed rolling on the reduction of curvature are mainly performed by FEM based on fundamental processing parameters. Differential speed rolling experiments by using low-weight Al1050/Al6061 bimetallic slab produced by continuous clad casting have also been performed for the validation purpose. As rolling experiments for numerous processing conditions are hard to achieve, limited number of experiments has been performed in this study. Simulation results based on parametric study provide a broad overview on the warping behavior in Al1050/Al6061 bimetallic slab rolling.
