• The B50 of NOG steels was evaluated via texture for different rolling processes.
• On comparison to all processes used, the cross-rolling led to highest average B50.
• Cross-rolling enhances Goss and γ-fiber after annealing.
• The better B50 values were obtained for symmetrical and cross-rolling processes.
• For asymmetric rolling process, cylinder diameter ratio changed slightly the texture.
The purpose of this work was to study the influence of different kinds of rolling on the magnetic properties of NOG steel, an electric steel widely used in electrical motors. These properties are highly correlated with the crystallographic texture of the material, which can be changed by rolling. Three kinds of rolling were examined: conventional rolling, cross-rolling and asymmetrical rolling. The crystallographic texture was determined by X-ray diffraction and the magnetic properties were calculated from a theoretical model that related the magnetic induction to crystallographic texture through the anisotropy energy. The results show that cross-rolling yields higher values of magnetic induction than the other processes.
