Advantages of cold rolling are listed below.
- In cold rolling operation, 50% to 80% deformation of metals is possible.
- The scale formation as well as oxidation of the metal is negligible which ultimately gives higher dimensional accuracy and better surface finish.
- Workpieces or sheets with thinner walls can be rolled using cold rolling.
- Final properties of the cold rolled metals are easily controllable.
- The strength of the cold rolled metals is high as they undergo strain hardening.
Disadvantages of cold rolling
Disadvantages of cold rolling are listed below.
- Very large amount of forces are required to perform cold rolling operations.
- Small reduction in thickness may lead to surface stresses and non uniform stress distribution.
