The subsequent annealing was just as that in industry. The texture distribution and development through the thickness were researched by ODF and reverse pole figure quantitative analyses, and the magnetic properties were measured. The results indicate that the deformation texture is similar to that obtained by traditional one,favorable deformation texture can also be found near the both outer layers of sheet, but they deviate obviously to the fast speed roll. Therefore, the deformation texture shows an asymmetry distribution through the thickness. After decarbon annealing, η-fibre increases,texture with a symmetry distribution reappears through the thickness: sharp Goss texture forms after the secondary recrystallization annealing, and the magnetic properties measured are not lower than that rolled by traditional one.
