Evolution of Hot Rolled,Normalized and Cold Rolled Texture of Non-Oriented Silicon Steel Produced by CSP

By using EBSD and X-ray diffraction technology,evolution of hot rolled,normalized and cold rolled textures of non-oriented silicon steel produced by a simulation process of CSP was examined.The results show that the texture types along the thickness in the hot rolled strip are substantially different,including B-fibrous texture,A-fibrous texture and rotated cube texture of {001}＜110＞ in the surface,subsurface and center layer of the hot rolled plate respectively.The difference is weakened in the normalizing process,but cube texture of {001}＜100＞ with certain strength remains in the center layer of the normalized plate.Both surface and center layer of the cold rolled plate consist of B-and A textures with {223}＜110＞ and {111}＜112＞ as their major textures respectively.Analysis shows the evolution of texture is mainly determined by the initial texture and microstructure.
