Roll Bending - an overview | ScienceDirect Topics
In temper rolling mills there are three common methods/actuators for flatness control, work roll crown, work roll bending and tilting of the roll gap. The most common method is the use of a constant work roll crown, which means that the work roll barrel has "a diameter profile", a difference in diameter along the barrel length.
