The invention relates to a method and a device for the positionally correct winding up of a metal strip in a coiling device, the hot strip being fed to the coiling device by a driving device with driving rollers, the driving rollers being tiltable in relation to one another by a controller by means of actuators for changing the gap between the driving rollers, and the controller being fed the position of the edge of the hot strip upstream of the driving device as a measured variable and as a setpoint reference variable, an optimization of the winding result of the rolled strip coil being achieved by the surface geometry of the rolled strip being determined as a measured variable and fed to the controller.

The invention relates to a flatness measurement and control system for metal strip, which makes it possible to obtain improved strip or coil quality by a simple and effective measurement of departures from flatness and to control the finishing parameters through the evaluation of a line pattern on the strip surface or on the end face of a coil as it is coiled.

摘要:
Method of measuring and/or controlling flatness during rolling. The flatness deviation is measured and expressed using orthogonal polynomials. A controlled variable is generated using an Internal Mode Control by comparing the expressed deviation with values of orthogonal polynomials supplied by a model. The comparison provides a control difference to control variables that influence bending, pivoting and axial displacement of the rolls and by multizone cooling.

The invention provides a device for heating a metal strip, which device allows the metal strip to be heated precisely and rapidly to a predetermined temperature, while taking up little space. The invention also relates to an apparatus that is suitable for producing hot-rolled metal strip, with which apparatus, despite the small overall space available, optimal heating, in terms of the hot-rolling process, of the rolling stock may be carried out. For this purpose, the device according to the invention is equipped with at least one inductively operating heating device, which comprises an inductor inducing an electromagnetic field, which inductor extends over the conveying path of the metal strip to be heated and the position of which is adjustable transversely to the conveying path depending on the width of the metal strip.
