Rolling is a process which reduces the thickness of a metal strip through crushing. The material passes through 2 rotating rollers, which apply a compression force to the material. The compression ratio is known as the work hardening rate.
- Reduces the thickness
- Increases the hardness and mechanical strength of the material
- Improves or deteriorates the surface condition, surface roughness (Ra, Rz)
- During rolling, the strip width is practically unaffected
- The material's grains extend parallel to the direction of rolling
