Cold rolling is a rolling process which is occurred at room temperature where the material shows strain hardening. Although it is named as "cold" rolling, the material is heated up by deformation to approximately 100°C and a high amount of coolant is used during the process in order to have a thermal equilibrium [2]. Cold rolling, as its ...

Chapter 4 Surface finish and friction in cold metal rolling

METAL FORMING SCIENCE AND PRACTICE The flattening rate W is a function of the real area of contact area ratio A and the ratio p Y of the mean contact pressure to the plane strain yield stress of the strip, i.e. = A Y p W W, (4.4) The theoretical flattening rate W is in the range 1–8, increasing with increasing mean pressure and falling with increasing area of contact ratio.
