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. The measuring accuracy of our system is +/- 1.5 mm.
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.
When using the EMG hotCAM centre position, a closed control loop can be realised in a finishing line. We use SMS X-Roll® - a product of the SMS Group that demonstrably stabilises the rolling process. With this combination of position measurement on the hot strip EMG hotCAM and the closed control loop, we offer comprehensive process optimisation in the hot strip area.

"Our strength lies in the fact that we define and solve tasks together with the customer. The intensive exchange brings positive effects for the successful implementation of joint projects. For example, together with our customers we were able to develop a control algorithm based on the measurement results of EMG hotCAM, which enables automated control of the rolling mill."
