Abstract Aiming at the behavior that stainless steel/carbon steel clad plate is prone to non-uniform extension and warpage during temper rolling,a finite element numerical simulation model for the temper rolling process of stainless steel/carbon steel clad plate was established, and the uneven deformation behavior of the temper rolling process of the stainless steel/carbon steel clad plate that has been industrialized and mass-produced and its possible lead to warpage Numerical simulation study of defects. On this basis, the heredity and evolution of the shape of homogeneous plate, asymmetric stainless steel/carbon steel clad plate and symmetrical stainless steel/carbon steel/stainless steel clad plate during temper rolling were compared and analyzed, and it was found that only asymmetric stainless steel/carbon steel clad plate is very prone to warpage defects in the process of temper rolling. At the same time, the effects of tempering and conventional rolling on the warpage defects of asymmetric stainless steel/carbon steel clad plates after rolling are compared and analyzed. The thickness-wise delamination characteristics of stainless steel/carbon steel clad plates and the influence of clad plate size parameters, leveling process and equipment parameters of leveling machine, etc. on the warpage defects of the plate shape are revealed. Afterwards, the warp height is proportional to the thickness ratio. For the skin-passing process, when temper rolling with equal tension, the warpage height after skin-passing is proportional to the tension; when temper rolling with unequal tension, the change of pre-tension has a great influence on the warpage defects after skin-passing; the warpage height after that is inversely proportional to the friction coefficient of the roll and the carbon steel layer surface. For the parameters of the leveling equipment, the warpage height after leveling is proportional to the diameter of the roll contacting the surface of the carbon steel layer, the lifting height of the anti-wrinkle roll on the entry side, and the distance from the contact roll on the surface of the stainless steel layer to the entry side. Finally, the numerical simulation results were verified by rolling experiments, which proved the accuracy of the temper rolling model of the clad plate. Based on the above research results, corresponding technological countermeasures are proposed, which provide a theoretical basis for the control of flat warpage during temper rolling of metal clad plates.
