Optical strip position measurement in the hot rolling stand

The hot rolling process is typically a combination of a reversing stand (roughing stand) and a finishing line with several rolling stands. Maintaining a defined position of the strip between the rolling stands is essential for process safety in a hot rolling mill. Continuous measurement of the strip position with our EMG hotCAM solution enables you to optimise the adjustment of the rolling force and gap. 

In reversing stands this leads to a reduction of the camber of the strip and thus prevents collisions of the strip with the mechanical strip guiding rail. Continuous control of the centre position in a finishing line also reduces strip guiding cobbles, which could otherwise result in serious damage and interruptions to the production process.
