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.

Abstract: A device for producing strip material, such as a hot strip. The device includes lateral guide elements which are arranged on both sides of the strip material and, in particular, along a roller table having several rollers, and at least one rotating wear body on each side guide element. In order to minimize the wear of guide elements when transporting the strip material over a roller conveyor, a speed control device regulates a rate of speed of the at least one wear element. Further, a position control device is provided for setting an extended position of the at least one wear element. The position control device sends control signals to a positioning drive for extending the at least one wear body to an extended position.
