Cold Rolling - an overview | ScienceDirect Topics

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 ...

Rolling (metalworking) - Wikipedia

Cold rolling cannot reduce the thickness of a workpiece as much as hot rolling in a single pass. Cold-rolled sheets and strips come in various conditions: full-hard, half-hard, quarter-hard, and skin-rolled. Full-hard rolling reduces the thickness by 50%, while the others involve less of a reduction.
