The principal factors affecting spread in hot flat rolling are geometric (initial width and height, roll radius) and tribological (roll roughness, friction coefficient, rolling temperature).
The factors affecting the frictional conditions in the contact zone are very important also for the design of the rolling mill. In particular, in order to calculate, by analytical formulae and FEM simulation, the rolling power and the maximum contact angle, the value of the friction ...
