Abstract

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 numberof experimental parameters so as to be used in wide ranges of temperature and chemical composition. Coupled with a FEMheat-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 showthat the calculation by the model prior to the production brings useful information to attain steel sheets with high quality.
