Metal Rolling Manufacturing Process

During the rolling process great forces act upon the rolls. Rolls will be subject to different degrees of deflection. In any particular metal rolling process, it is important to understand how these deflections will affect the rolls and hence the work being rolled. The rolls initially start out flat.
