<p>Aiming at the problem of non-uniform and uncoordinated deformation in the asynchronous rolling (ASR), which will cause the clad plate bending and affect the subsequent processing, this paper proposes the model for predicting the clad plate–bending curvature after rolling. This paper systematically analyzes the stress characteristics of the micro-unit element in the roll gap, and the static equilibrium equations of the metal layers in each deformation zone (DZ) are constructed. Then, the coordinates of the neutral points are obtained by combining the boundary conditions to solve the rolling pressure distribution equations, and finally constructs the bending curvature model of the bimetallic clad plate. The modeling process considers the plate-bonding process and the shear stress inhomogeneity along the vertical side, as well as the evenness of the normal stress, and the bending curvature is caused by the comprehensive influence of the shear strain difference and linear strain difference. The average relative error between the theoretical model and the experiment is 8.38%, which verifies that the established model has great reliability. This article analyzes the curvature variation, microstructure, and mechanical properties of the bimetallic clad plate, and finally proposes the effective measures to suppress the clad plate curvature. The curvature, cross shear area (CSA) length, and proportion of various process parameters are analyzed to study the clad plate–bending deformation, which indicates that the bending extent varies nonlinear with the CSA length in ASR clad plate. In summary, the theoretical model can be used to quickly calculate the bimetallic clad plate curvature and optimize the process parameters in ASR, which is valuable for the comprehensive control of the shape and properties in manufacturing.</p>
