Aluminum Sheet Production: General Principles of Cold

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 100C and a high amount of coolant is used during the process in order to have a thermal equilibrium [2]. Cold rolling, as its

An investigation on the roll force and torque fluctuations

the rolling process, especially in a cold strip mill. If the thickness variation of the hot-rolled aluminum strip can be reduced, it will be possible to increase the production speed of the cold strip mill. These claims set new demands on the acceptable rolling forces and torques which, together with the roll pass design, have a significant
