Rolling schematic view Rolling visualization. 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 is classified according to the temperature of the metal rolled.

If the mill heats the aluminum, this process is called hot working. The specific temperature range for hot working varies by alloy. For example, 3003 aluminum is hot worked at between 260 to 510°C (500 to 950°F), according to AZoM. Hot rolling prevents most or all work hardening and allows the aluminum to remain ductile.

Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The preconditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physicalmechanical properties of the material on the working layer.
