In autumn 1984, Friedr. Gustav Theis Kaltwalzwerke GmbH in Hagen-Halden put the first cold rolling mill with CVC^® technology into operation. Today, CVC^® is the world's most widely used system for achieving the desired profile and flatness of hot and cold-rolled strip. The principle is simple: The CVC^® rolls are ground to an S-shape in a mirror-inverted arrangement. In the neutral position (neutral crown), they form a parallel roll gap. Axial shifting of the rolls in opposite directions creates the effect of a continuously variable crown (positive or negative crown). Parallel to the first practical application, a related technological process model was developed on the basis of physical-mathematical approaches, which allows, among other things, the settings for CVC^® shifting and work-roll bending to be calculated.
