Assumptions
1) The arc of contact between the rolls and the metal is a part of a circle.
2) The coefficient of friction, µ, is constant in theory, but in reality µ varies along the arc of contact.
3) The metal is considered to deform plastically during rolling.
4) The volume of metal is constant before and after rolling. In practical the volume might decrease a little bit due to close-up of pores.
5) The velocity of the rolls is assumed to be constant.
6) The metal only extends in the rolling direction and no extension in the width of the material.
7) The cross sectional area normal to the rolling direction is not distorted.
Theory of Rolling was covered as a topic in the book Production Engineering Sciences. Page 484.
