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 optimized adjustment of the rolling force and gap.
In reversing mills this leads to a reduction of the camber of the strip and thus prevents collisions of the strip with the mechanical strip guiding rail.
The continuous control of the centre position in a hot rolling mill also reduces cobbles (outbreaks) of the strip, which lead to serious damages and production stops.
With the measured parameters transmitted to the level-2-system, the line operator is able to realize a closed loop system (sensor and mill) for camber reduction and optimized strip positioning in the hot rolling mill.
