  • Cold Work Annealing ProcessGoogle Sites

    Cold rolling is often used commercially in order to produce sheet metal plates and bars. When a metal is cold rolled it is plastically deformed as it is forced between the two rolls. The metal is compressed by the rolls and the plastic deformation is in the direction of the rolling. Unlike a tensile test no necking occurs in the metal specimen.

    Rolling is a metal forming process in which metal stock is passed through a pair of rolls. There are two types of rolling processflat and profile rolling. In flat rolling the final shape of the product is either classed as sheet also called "strip" (thickness less than 3 mm ) or plate (thickness more than 3 mm). In
