Implementation of a new failure detection system

The gimbal-mounted system of the feeder belt for steel sheets at Arcelor Mittal in Ghent may break down, which would have serious financial consequences for production. The existing failure detection system can anticipate disruptions a couple of days in advance. The purpose of the research performed by Flanders Make was to develop a new detection mechanism that would anticipate failures sooner. This would give maintenance teams more time to prepare for interventions. However, there was a limitation because we could only consider existing signals such as motor current and rotational speed. By applying the failure detection mechanism to automatically monitored speed situations with a constant rotational speed, the signal-to-noise ratio of the detection mechanism could be improved considerably. As shown in the figure below, a failure can now be detected 10 days earlier compared to the existing system.
