Abstract:
In a multi-stand rolling mill train, a strip successively runs through individual rolling stands. The strip—always as seen in relation to a rolling centre line—is threaded into each of the rolling stands with known respective head offset and inlet-side head pitch, and therefore a strip head emerges with the respective head offset, a respective outlet-side head pitch and a respective outlet-side head curvature. The respective outlet-side head pitch is determined on the basis of respective inlet-side head pitch and pass reduction which takes place in the respective rolling stand. The respective outlet-side head curvature of the strip is determined based on respective measured and further data. The respective outlet-side head curvature is used to determine a respective control intervention for the respective rolling stand and/or the one arranged directly downstream and to drive the corresponding rolling stand in accordance with the respective determined control intervention.
