THE IMPROVED CONTROL FOR AN ALUMINUM 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 an d consistency of the rolled product. The metallurgical and dimensional properties of rolled strip must be carefully controlled if the produc t 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 s ystem that runs under the supervision of an expert system. The system has been developed around an expert system shell and tested in simulat ion.
