In rolling the metal is plastically deformed by passing it between rollers rotating in opposite direction. To provide suffi cient information on the rolling of aluminium and the characteristics of rolled products to ensure that students users and potential users can understand.

The starting material is usually large pieces of metal like semi finished casting products such as slabs blooms and billets. Part of this covers the history of metal rolling from the first known drawings of a mill to the state of the art rolling equipment available today.

Novelis is the leading producer of flat rolled aluminum products and the world s largest recycler of aluminum. A brief history of metal rolling for sheet and plate products. Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. This process is used for making the vast majority of aluminium products from spectacle frames telephone bodies aeroplane fuselages or spaceship bodies.

After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. Many alloys have been formulated specifically for rolling to plate sheet and foil.
