Flatness measuring system

direct-contactautomaticstrip

The use of flatness measurement alone without control already achieves a noticeable increase in productivity because strip breaks can be effectively prevented or the mill can be operated at the maximum possible speed for the particular unflatness. If the mill has the necessary adjusting elements, the Automatic Flatness Control (AFC) results in an effective improvement in quality. Control results of ± 4 I-units referred to the respective nominal curve are realistic. With our detailed know-how of the interplay between measurement, control and rolling mill we are on of the few manufacturers able to supply complete control systems for the strip shape – from the sensor through to the control of the adjusting elements From the pivoting of the rolls through to the combination of pivoting, bending, shifting of the intermediate rolls and zone cooling and far more – we have a command of the whole spectrum of shape control.
