Principles of Rolling: The rolling is a process which consists of passing the metal through a gap between rollers rotating in opposite direction. This gap is smaller than the thickness of the part being worked. ... This equation (2) neglects the friction at the roller-work interface, and therefore gives lower estimation of the rolling load.
