In addition to the thickness of the strip, the geometry of the cross section of the strip including the thickness profile and the relevant edge drop (i.e., the shape of the strip at the edge) are important parameters in determining the quality of the rolled profile. The geometry of the strip cross section can be influenced by the geometry of the rolls in the roll stand, i.e., the camber of the rolls. It is known that camber can be influenced mechanically, e.g., by moments, displacement or bending. This process is effective with CVC rolls or taper rolls. However, CVC rolls can only be preset in an unloaded state. Therefore, they are used exclusively for presetting. Furthermore, this process is extremely expensive and cost-intensive, and shortens the lifetime of a roll stand.
There is a need to provide a process and a device for carrying out this process that will make it easier to influence the geometry of a rolled strip.
