Texture Evolution of High Grade Non-oriented Silicon Steel Produced by 20 mm Thin Slab

In this paper texture evolution of high grade non-oriented silicon steel produced by 20 mm thin slab in the course of hot rolling,normalizing,cold rolling and annealing process was investigated. The texture of samples was measured by EBSD. The results show that the texture intensity through thickness of hot rolled strip change obviously,Goss texture has highest intensity in the S = 0.9 layer,and Quite strong{221} ＜227＞ dominates in the S = 0.5 layer,while rotate cube texture takes a leading role in the S =0 layer. In the surface and center layer of the cold normalized strip,the main texture is {223} ＜110＞,while the main texture in the S = 0.5 layer is {332} ＜113＞. In the each layer of the cold rolled sheet,the {001} ＜110＞-{223} ＜110＞ has strong intensity. The annealed sheet has a strong {001} ＜130＞ texture while a certain amount of γ-fiber texture occurs in the surface layer.
