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.
