The improved control for an aluminium hot reversing mill using the combination of adaptive process models and an expert system

Of major concern to the producers of aluminium sheet is the quality and consistency of the rolled product. The metallurgical and dimensional properties of rolled strip must be carefully controlled if the product is to be of prime quality. Mill control systems have been introduced to automate many tasks normally performed by the mill operator. This paper details the development of a prototype mill set-up and control system that runs under the supervision of an expert system. The system has been developed around an expert system shell and tested in simulation.
