Thickness: from 0.1 to 5 mm
Width: up to 400 mm (on study)
Rolling is a manufacturing process by plastic deformation. This deformation is obtained by continuous compression as it passes between two contra-rotating rolls (rotating in opposite directions to each other) called a “rolling mill”.
The purpose of rolling is to reduce the thickness of the metal (possibility of obtaining specific tolerances) and to modify its mechanical characteristics (Rm, Rp0.2, A%).
Cold rolling of a material make it become hard, which results in a loss of ductility (the property of a material to stretch without breaking) and hardening.
