Summary:A mathematical model has been developed for predicting phase transformation of hypoeutectoid steels during continuous cooling, with a special reference to the application to the temperature simulation in hot strip rolling. The model contains only a small number of experimental parameters so as to be used in wide ranges of temperature and chemical composition. Coupled with a FEM heat-transfer model, this model predicts the temperature of steel strips on the run-out table of a hot strip mill with great accuracy. This model is applied to the investigation of the effect of processing conditions on hardness of 0.5 mass%C steel sheets produced in the hot strip mill. The results show that the calculation by the model prior to the production brings useful information to attain steel sheets with high quality.
