This paper describes a recent plate cooling modernization project. The MULPIC is designed to provide the high cooling rates and temperature accuracy needed to achieve the combination of high strength and toughness. Flatness accuracy is controlled using edge masking, crown valves and head tail masking. The control system incorporates flexible target cooling to achieve the desired time-temperature path. This paper also 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.
