Rolling (metalworking) - Wikipedia">Rolling (metalworking) - Wikipedia
Rolling (metalworking) 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 dough. Rolling is classified according to the temperature of ...
