Metallographic Analysis of Non-Orientation Silicon Steel W20 in Different Shearing Deformation Area
In order to further understand the relationship between technology and metallographic microstructure for the large-scale production of non-orientation silicon steel, hot assembles rolling mill samples at different shearing deformation strip were selected and analyzed. The results show that the surface microstructure in finishing section at the first meeting to the fourth-pass is band-shape deformed ferrite plus equiaxed recrystallization ferrite, while the center is deformed ferrite. With the increase of shearing deformation, number of rheological ferrite increase, and become more slender.
