The skin-pass is a cold rolling process that provides a small reduction in thickness (below to 2%) of the rolled material (Roberts, 1978). This mechanical process is used to achieve a desired final thickness and flatness of the rolled sheet, while attempting to improve their surface finishes and eliminating Lüders bands (Lenard, 2013). At the ...
Skin-pass rolling is often the final forming step in the production of cold rolled steel sheet , and it is applied to either eliminate (upper and lower yield stress behavior) yield point elongation, or to improve the surface of the strip, or both . The main effect of skin pass rolling is to create mobile dislocations and not to reduce the ...
