Abstract: The invention relates to a roll stand and a method for rolling a rolled strip. The roll stand (100) comprises at least one roller housing on the drive side (AS) and one roller housing on the control side (BS) of the roll stand.

Abstract: The invention relates to a method for controlling a rolling process, in which a metal strip is rolled flat by use of at least one roller. It is known from the prior art that the relative position of a neutral point represents a measure of the instantaneous stability of a rolling process. However, traditional methods for calculating the position of the neutral point do not accurately represent the actual properties of metal and therefore have only limited usefulness for predicting the stability of a rolling process. In order to allow better control of a rolling process for rolling a metal strip with regard to the actual behavior of the metal strip, the invention proposes a new method for calculating the relative position of the neutral point, in which in particular the flat yield stress ke and the hydrostatic pressure pNH at the neutral point are incorporated.
