Abstract

Based on elasto-plastic deformation straightening theory and by adopting 11 rolls straightening plates , the isothermal residual curvature straightening process was proposed for stainless steel clad plate. The mathematical model of straightening was established to realize plate shape finishing and stress reforming. By using finite element analysis software, establishing straightening process and determining intermesh, the effects of intermesh on shape and residual stress were analyzed. The results indicate that the straightening process met the finishing plainness of stainless steel clad plate after rolling. Longitudinal residual stress of the clad plate was evenly distributed across width. The cladding plate and steel substrate were observed to be symmetrical and the ascent of stress near the edge was greater. Longitudinal residual stress across length was distributed with the wave of pull-press-pull and the cladding plate and base plate were observed to be symmetrical. The above researches are based on the previous theory of the application of stainless steel clad plate straightening technology.

Keywords: FEM analysis, intermesh, residual stress, roller straightening, stainless steel clad plate.
