Hot rolling

Hot rolling is a metallurgical process in which the metal is passed through a pair of rolls and the temperature of the metal is above its recrystallization temperature, as opposed to cold rolling, which takes place below it. This permits large deformations to be achieved with a low number of rolling cycles. The action of hot rolling a metal will cause elongation of the grain structure in the direction of rolling. Hot rolling is mainly used to produce sheet metal, or simple cross sections from billets.
