Abstract
A flatness-measuring device for a hot-rolled strip within a hot-rolling mill includes an entry-side deflection roller and an exit-side deflection roller. A central deflection roller is arranged between the entry-side deflection roller and the exit-side deflection roller. The central deflection roller is used as a flatness-measuring roller. To prevent the hot-rolled strip from departing laterally during a flatness measurement, the flatness-measuring device has a sensing apparatus for sensing an actual position of the hot-rolled strip. An adjusting apparatus is connected to the sensing apparatus and to at least one of the deflection rollers. The flatness-measuring device is designed to vary an angle between a longitudinal central axis of the deflection roller respectively connected to the adjusting apparatus and a longitudinal axis of the flatness-measuring device based on a deviation of the actual position of the hot-rolled strip from a predefined target position.
