SUMMARY:An integrated technological solution for enhanced productivity and quality by superordinated AI approach for product changes at cold rolling mills
DESCRIPTION:X-Pact® Superior Control, as an integrated technological solution that comprises artificial intelligence and expert systems, actively provides optimized rolling strategies for level 1 and level 2 systems and implements the presets in real time for strip changes. The objective is thus to create a technologically self-optimizing plant that continuously enhances its product quality over its whole life cycle.

The advantage of this step beyond the limits of the level 1 and level 2 systems is that interlinked and separately runnable structures can be mapped. In concrete terms, this means that the automation system does not require a fixed differentiation between the level 1 and level 2 systems. Both systems work in a closely connected and coordinated manner, thereby opening up a multitude of new technological possibilities.

The paper describes, how an expert system, developed as part of X-Pact® Superior Control,  automatically calculates the optimum strategy for all product changes, i.e. the optimum combined method of operation from the technology clusters such as flatness, thickness, etc. This look back at the past can now be done as often as needed based on mass data. The next step, therefore, is to supply digital AI systems to provide a forecast for the optimal product change strategy.

As soon as the artificial intelligence provides a sufficient hit rate in its prediction, it generates added value in the form of an improved off-gauge length for strip flatness and thickness and increased product change stability. This is because the proposed strategy from the digital AI system can directly be coupled to the control of the technology clusters of level 1 and level 2 systems. These AI systems provide optimized strategies for level 1 and level 2 systems and implement the presets in real time for strip changes.
