During the process of hot rolling, a metal is given its final shape by plastically deforming the original stock. This paper shows how variables, specifically the temperature, at each point in the deformation zone can be modelled using a multielement bond graph approach. Low-carbon steel has been considered and the modelling is described for single-pass hot rolling. Surface and centre temperature distributions are shown, and simulation results are found to be in good agreement between the two modelling techniques of bond graphs and finite element analysis.
