Question

7. Roller is used for levelling
​

Answer 1

Answer:

Roller levelling is a forming process used to remove the residual stresses and imperfections of metal strips by means of plastic deformations. During the process the metal fibres are subjected to cyclic tension-compression deformations leading to achieve flat product.

Answer 2

Answer:

Explanation:

Roller is used for levelling model is based on classical beam theory to calculate the induced strain distribution through the strip, and hence the evolving elastic/plastic stress distribution.
