MATHEMATICAL-MODELS FOR PREDICTING MICROSTRUCTURAL EVOLUTION AND MECHANICAL-PROPERTIES OF HOT STRIPS

Mathematical models for predicting microstructural evolution and mechanical properties of hot strips have been reviewed. The metallurgical features of the hot strip rolling are discussed and the fundamental idea of their modeling is introduced. As applications of the mathematical models, the on-line prediction of the microstructure and strength, the resistance to hot deformation and the cooling curves affected by the heat evolution due to transformation are given. Finally, the future work and prospective of the mathematical model in hot strip rolling is also presented.
