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 center 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.

Abstract: During the bending of sheet metal sections (1, 2) in particular for forming can edges using a bending machine, the sheet metal is pre-treated at a flexing station (50) before reaching the bending station. The contact position (x, y, y?) of a sheet on a measuring plate (38) is measured and the signal representing the contact position is reproduced on a display (25), enabling the operator to adjust at least one element (7, 8, 9, 20) of the flexing station in accordance with the deviation of the actual contact position from the target contact position, either manually or by means of a drive. The signal can also be used to automatically adjust at least one element of the flexing station.

Abstract: Disclosed is a rolling mill comprising a roll stand with working rolls, a roll train located at the feeding end of the roll stand, and a control device. The working rolls form a roll gap. The control device triggers the roll stand such that the working rolls rotate at a certain peripheral speed while triggering the roll train located at the feeding end of the roll stand in such a way that the leading edge of the strip-shaped rolling stock reaches the roll gap at a feeding speed that is greater than the peripheral speed. The control device adjusts the peripheral speed and the feeding speed to each other in such a way that a potential angled position of the leading edge relative to the roll gap is at least reduced as a result of said adjustment.

Abstract: The invention relates to a method and device for operating a hot rolling train with at least one edger and at least one sensor with which the strip end position is determined by means of a linear recording of the infrared radiation from the rolled strip and whereby an optimization of the strip width distribution is achieved by means of a calculation system.
