Finite element simulation of cold rolling of thin strip

In this work, the authors use a full 3D rigid plastic finite element method (FEM) to simulate the thin strip rolling taking into account the modelling of friction variation in the roll bite. A comparison of the computed results with measured values was conducted. The characteristics of the distribution of the velocity along the width of strip at the exit of the roll bite and the spread of strip for the different crown factors are presented in this paper. The modelling of the shape, profile and flatness for cold rolling of thin strip with friction variation is also discussed.
