ABSTRACT:
A process for rolling a metal strip for reducing its thickness and for increasing the maximum reduction attainable per pass using a cooperative type rolling mill comprises applying differential separating forces to the metal strip without changing the magnitude of the compressive force applied to the rolls. By doing this, the maximum strip tension and the forward tension required to pull the strip through the mill may be reduced. The maximum strip tension and the required forward tension force may further be reduced by driving at least one work roll at a desired value of torque as well as applying differential separating forces. The cooperative type rolling mill uses a roll spacing arrangement to space at least some of the rolls for reducing the separating force applied to the metal strip at selected roll bites. In addition, individual drive motors to drive the work rolls at desired torque values may be utilized.
