New cooling concept in hot strip mills “Microstructuretarget cooling”

Abstract

The transformation model and the model-predictive coolingsectioncontrol system not only have decisive advantageswhen it comes to the production of multiphase steels; thequality of other materials such as highly carbonized steels,tool steels, transformer sheeting and many other materials isalso improved.
Especially for older plants with many restrictions andlimitations, the new cooling-section automation system allowsfor flexible manufacture of modern steel grades. Although theimplementation of the micro structure target cooling systemalone may result already in the required flexibility and quality,additionally by small mechanical modifications a plant maybe brought to its peak-performance being ready for thechallenges in future.
