Cold Rolling

Cold Rolling In the cold rolling process, a hot-rolled 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.

Improvement of thickness tolerances in aluminium cold rolling

Backup roll eccentricity is not only the result of grinding and roll assembly tolerances, but can also be thermally induced during work roll changes and other stoppages. Strip hardness variation is less well understood, but an earlier ABB study has shown that for thin strip, cyclic hardness variations as small as 2% in the incoming strip can have a large impact on thickness deviation.
