The finite element technique has been selected to study the hot rolling process because it offers the best alternative to analyse the complexities of the process. These include: non-linearity of the material behaviour, boundary conditions and contact. It has been shown from the previous chapter that the method is capable of handling these non-linearities and has been used successfully to analyse a wide range of metal forming operations. This chapter aims to point out the modelling techniques and methodologies (steps) involved in undertaking thermo-mechanical simulations of the rolling process. This is done by means of a series of case studies.
