Abstract: A generalized approach to the modelling of transient heat flow in rolled steel during air-cooling in billet mills is presented. The mathematical development starting with the relevant differential equations and their modelling using the Hills� integral profile method give polynomial functions which characterize the transient heat flow in the workpiece and establishes an optimal control law for static cooling conditions. An experimental validation test enabled the final model to be obtained as a function of the rolling speed and shows that a good functional correspondence exists between the model and the data reported in the literature.
