ROLLING OPERATIONS

Rolling is a metal forming process in which a metal workpiece is passed through one or more pairs of rotating rollers to reduce its thickness and improve its shape and surface finish.

It can be performed hot (above the metal’s recrystallization temperature) or cold (below it). Hot rolling improves ductility, while cold rolling increases strength and surface quality. Rolling is widely used to produce sheets, plates, bars, and structural shapes in manufacturing.
