Rolling of Metals: Process and Principles (With .

The above equation (4) gives the relationship between the geometry parameters of the rolling process, the angle of bite, the draft, and the radius of rollers. In order to ensure that the metal will be shifted by friction, the angle of contact (α) must be less than the angle of Friction (β), where tan β = µ (the coefficient of friction between roller surface and metal).
