Abstract
The texture inhomogeneity during rolling is one of the greatest problems. Especially, shear textures develops more easily during ferritic rolling of steel sheets at high temperatures owing to friction between rolls and the material. In this study, the influence of front and back tensions on the texture development during ferritic rolling has been studied. The rolling textures were simulated using the full constraints Taylor-Bishop-Hill model with the strain history obtained from finite element analysis. The calculated textures showed that the back tension rolling could reduce the shear component more effectively than front tension or rolling without tension. However, the experimental results showed that the tension effect was very small compared to the prediction. The results were discussed based on the effects of friction, initial sheet texture, back tension, and flow stress.
