Thermal-Mechanical Modelling of the Flat Rolling Process

Thermal-mechanical modelling of hot, warm and cold rolling is presented. The dependence of the accuracy and consistency of the predictions on the boundary conditions - heat transfer and friction - and on the initial conditions - The resistance of the material to deformation - is discussed.
