Roller Straightening Process and FEM Simulation for Stainless Steel Clad Plate
View through CrossRef
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.
