Cold Rolling. In the cold rolling process, a hotrolled coil is made thinner by passing it between two rolls at room temperature. Not only is the thickness of the material made uniform, but the internal structure is made homogeneous at a microscopic level, and the surface of the roll is transferred to the material to provide a polished finish.

The theoretical framework is developed for a new theory of cold rolling thin metallic foil. Unlike previous theories, the work rolls are allowed to deform to a noncircular profile and finite regions of noslip between strip and work rolls are allowed to occur in the roll bite. The theory predicts that plastic reduction occurs near entry and ...
