Predicting the microstructure obtained in cold‐rolled strips is of major importance with regard to optimizing the production of deep‐drawing steels with high and defined mechanical and technological properties. By using the hydrodynamic rolling theory of A. Kneschke, it has been possible to determine the effects of the most important rolling parameters and also of the rolling strategy on the velocity field and on the in‐homogeneous distribution of deformation over the strip thickness. Rolling on experimental laboratory facilities has provided the opportunity to observe the texture evolution. The tests were carried out on two deep‐drawing steel grades IF and ULC. The initial thickness of the strip samples was 3.0 mm. The textures were determined at 3 locations over the strip thickness by means of pole figure measurements according to the X‐ray diffraction method.
