Rolling (metalworking) Wikipedia

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property The concept is similar to the rolling of doughRolling is classified according to the temperature of the metal rolled If the temperature of the metal is above its
