In the rolling 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 crosssectional 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 equipment, rolling is done in the
#0183;#32;The amount of deformation R achieved in a flat rolling operation (thickness reduction) is determined by the relationship: R = * (H H 0)/H 0. A machine used for rolling metal is called rolling mill. A typical rolling mill consists of a pair of rolls driven by an electric motor transmitting a torque through a gear and pair of cardans.

Rolling, in technology, the principal method of forming molten metals, glass, or other substances into shapes that are small in crosssection in comparison with their length, such as bars, sheets, rods, rails, girders, and wires. Rolling is the most widely used method of shaping metals and is particularly important in the manufacture of steel for use in construction and other industries.
