Texture evolution in 50W270 high-brand non-oriented silicon steel produced by CSP route

This article focuses on texture evolution in 50W270 high-brand non-oriented silicon steel produced by CSP in hot rolling, normalizing, cold rolling, and annealing processes. The texture in the whole process was measured and analyzed by electron back-scatter diffraction. It is found that the texture along the thickness direction in hot-rolled strips changes obviously:there are mainly copper, brass, and Goss textures in the surface layer; the 1/4 layer has weak Goss texture and rotating cube texture; γ-fiber texture, rotating cube texture, and weak α-fiber texture appear in the center layer. Compared with hot rolled strips, the texture changes little for the normalized strip surface and 1/4 layer, but rotating cube texture and α-fiber texture are enhanced in the center layer. Quite strong α-fiber texture and γ texture appear in every layer for cold-rolled strips. Compared with cold-rolled strips, α-fiber texture almost disappears, but cube texture and Goss texture appear in annealed strips.
