Numerical and physical modelling of cold rolling of thin strip
In this paper,the crystal plasticity finite element modelling (CPFEM)has been carried out to simulate the rolling texture development of IF steel during cold rolling,and the effect of the reduction and slip systems on strip surface texture has been discussed.In order to discover the effects of the friction in the roll bite on the rolling model and strip surface quality,a set of oblique roughness textures were manufactured on aluminum samples and compression tests were conducted to obtain the effect of different textures on the deformation behavior of surface asperity.It is found that the stress is high and changes significantly at the initial compression stage but it tends to be stable when the total reduction increases.This is helpful in determining the relationship between the surface asperities and roll bite friction,and improving the practical models of cold strip rolling.
