Rolling Mills and TypesTypes of Rolling MillsConclusionRolling mill is the extensively used process and the most expensive one in terms of equipment costs. It accounts for almost 90% of the metal produced by forming. In therolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipme
