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.
