Cold rolling is a rolling process which is occurred at room temperature where the material shows strain hardening. Although it is named as "cold" rolling, the material is heated up by deformation to approximately 100°C and a high amount of coolant is used during the process in order to have a thermal equilibrium [2]. Cold rolling, as its ...

ALUMINUM COLD MILL - ameteksurfacevision
In the aluminum industry, an aluminum strip – which has already undergone hot rolling and other processes such as cleaning and pickling – is cooled to room temperature and then fed into a cold mill roll line. This strip passes through a series of rollers several times, which gradually reduces its thickness.

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
