Abstract : Flatness defects in thin strip cold rolling are a consequence of buckling due to roll thermo-elastic deformation and the resulting heterogeneous strip plastic deformation. A coupled rolling - buckling model has been developed Abdelkhalek et al. 2011. It has shown that i taking buckling into account results in completely different stress fields and fits correctly the measured on-line residual stresses under tension -stress-meter rolls-; ii coupling buckling in the post-bite area and the rolling model, whatever the technique, changes little the in-bite fields. The model is applied here to the effect of friction on optimal setting of a flatness actuator, Work Roll Bending.
