Optical position measurement at hot strip

Our solution for your hot processes Ideal strip positioning The hot rolling process is typically a combination of a reversing mill (roughing mill) and a multi-stand hot rolling mill (finishing line). For the process reliability in a hot rolling mill it is extremely important to keep a defined position of the strip between the hot rolling stands. The continuous measurement of the strip position allows an optimised adjustment of the rolling force and gap. In reversing mills this can lead to a reduction of the camber of the strip and thus prevents collisions of the strip with the mechanical strip...

Functional principle During hot rolling processes in a multi-stand rolling mill, the position of the moving hot strip changes between the rolling stands. By detecting this position, the optimised adjustment of the rolling force and gap is possible, to keep the strip in the middle of the line. By knowing the strip position at each rolling step, the online control of the slab/strip movement becomes much more effective. Furthermore, it helps to avoid critical movements of the strip, leading in the worst case to cobbles of the hot strip between the rolling stands. EMG hotCAM provides not only the...

Closed control loop with X-Pact® Strip Steering Control Using the EMG hotCAM centre position, a closed control loop can be realised in a finishing line. EMG draws on the many years of experience of the SMS Group, which has developed the SMS X-Pact®, a product that demonstrably stabilises the rolling process. With this combination of position measurement on the hot strip EMG hotCAM and the closed control loop, EMG offers comprehensive process optimisation in the hot strip area. Customer benefits » Sheared strip ends are reduced » Fewer unscheduled roll changes necessary » Improvement of process...
