Abstract Force analysis of interlaminar vacuum hot rolling deformation process for wide stainless steel clad plate was carried out. The hot rolling deformation area was divided into two intervals marked as I and II， and the force equilibrium equations of each interval were established employing the principal stress method. The length and resultant stress of each deformation zone were obtained according to the boundary conditions and yield criterion， and the mathematical model for calculation of rolling force is derived. Based on this model， the influence of rolling process parameters on different stress distribution in wide stainless clad plate rolling intervals was analyzed. Substituting the actual parameters into the calculation formula of rolling model， the calculated values were obtained by application of Matlab programming and compared with the measured values. The results indicate that the rolling force model can predict the rolling force accurately and meet the engineering requirements. The study on clad rolling process contributes to the optimization of forming process and product performance prediction， which can provide reference basis for future research and development of this kind of materials.
