Abstract: Taking a high magnetic oriented silicon steel slab prepared under low temperature heating process as starting material, the main composition of texture and the Goss texture distribution in hot-rolling, normalizing, cold rolling and primary recrystallization stages were analyzed by using EBSD technology. The results show that the surface layer of hot-rolled sheet is the origin of Goss texture, and in the transition zone, the {100}, {110} and {111} plane textures have a certain proportion, and the {100}<110> cubic texture accounts for the largest proportion of central deformation zone. There are more{110}<112> brass texture and{110}<001> Goss texture on the surface of the normalized sheet, and there are more {114}<418> oriented textures in the transition zone and the central deformation zone, and {112}<110> α linear texture accounts for the largest proportion in the central deformation zone. The cold rolled texture is dominant by {112}<110> α texture, though there are many {100}<110> textures. After decarburization annealing and nitriding, the primary recrystallization texture is dominant by both of the{114}<418> oriented texture and {111}<112> γ linear texture.
