This paper describes a recent plate-Steckel mill modernization project applying the MULPIC® cooling technology coupled with existing conventional laminar cooling to produce high-strength plate and coil. A description is given of the automation control scheme implemented to give accurate temperature control as well as the advantages of intermediate cooling during the holding phase to improve mill productivity. The paper demonstrates the importance of the advanced model-based automation coupled with sophisticated adaptation. Insights are provided by predictions of the plate temperature and microstructural evolution during cooling. Typical performance results are given, which demonstrate the accuracy that was achieved.
