Abstract

For high quality hot strip mills, the tight control of the strip flatness at the exit of the finisher is more and more a decisive factor where the final strip quality is concerned. Therefore, the performances of the flatness gauge, especially its accuracy, fast response time and reliability becomes of prime importance. These aspects are especially critical with thin strip rolling practices where faster rolling speeds may generate uncontrolled strip movements that can considerably disturb conventional flatness gauges. Since some years, other processes, such as wide plate mills, are more and more in need for flatness gauges in order to control the quality of the plate in the hot or cold section. This type of applications required new flatness measurement solutions, providing flatness measurements that meet and exceed international standards.
