Parametric Study of the Hot Rolling Process Using FEM

Numerical Simulation has become a quite important tool in the Manufacturing Industries. Rolling process is one of the most popular processes in manufacturing in order to make different parts with a long range variety of dimensions. In this procedure the internal raw material transform into desirable shape by at least rolls. In comparison with other methods for analysing the rolling process, the finite element method is the most practical and accurate one, so a coupled thermo elastic plastic three dimensional finite element model is considered to analyse the hot rolling process. In present research the influence of Modelling and Simulation of various parameters such as geometry of the slab, temperature, friction between work-rolls and slab, percentage of thickness reduction, rotational speed of work-roll have been studied on process. Outputs like temperature distribution, stress, strain and strain rate fields, roll force have been obtained through different inputs. The outputs of finite element simulation are used to investigate the effects of parameters on product integrity and mechanical properties
