“…The importance of Goss orientation grains in the surface layer of hot rolled strip was studied by Bottcher. 17,18) The surface of hot rolled strip was exfoliated from one side and two sides, respectively. The result shows that it had no effect on secondary recrystallization when exfoliation from one side, but the secondary recrystallization did not occur when exfoliation from two sides.…”

The texture of high permeability grain-oriented silicon steel produced by Thin Slab Casting and Rolling process through adopting low slab reheat temperature and AlN as the main inhibitor has was studied. The results show that the microstructure of the hot rolled strip is nonuniform through the thickness, and the Goss texture with a maximum intensity mainly concentrated on the surface. The microstructure of the normalized strip is fully recrystallized, and the Goss texture is in both the surface and the subsurface layer, with a maximum intensity in subsurface layer. The microstructure of the cold rolled strip is fibrous tissues, the £-fibre texture is the main texture in the surface, and the f223gh110i is the dominant texture in both the subsurface layer and center layer. The microstructure of the decarburization annealed sheet is fully primarily recrystallized, and the £-fibre texture is the main texture. The Goss grains abnormally grow after high temperature annealing, it is the single Goss texture.

The medium temperature reheating and two-stage cold rolling process were adopted to produce industrialized Grain-oriented silicon steel. Results showed there were three sections (surface layer, transition layer and central layer) along the thickness direction on hot rolled sheets. Surface layer was occupied by complete recrystallization grains with average grain size 42.81 µm, while the central layer mainly consisted of fibrous microstructure. The Goss texture appeared only on surface layer with content 3.44%∼3.65%. After the first cold rolling with 72% reduction and decarburization annealing, the primary recrystallization occurred and average grains size reached 19.0 µm, simultaneously accompanied with texture rotated to λ, γ fiber texture and Goss texture dropped to 2.89%. Adopting the second cold rolling with 58% reduction, the cold rolled sheet consisted of deformed fiber microstructure and the texture maintained γ fiber texture with a peak at {111} <112>. The precipitates in hot rolled sheets comprised Cu2S and few AlN, and the average particle size was ∼14 nm. The inhibitors in the decarburization annealing sheet were mainly AlN, Cu2S, MnS and their composite precipitation, which were spherical or massive with the average particle size ∼21 nm. The single Goss oriented grains with average grain size 9.41 mm were obtained after high temperature annealing, and the intensity reached 873.30. The final magnetic properties were: B8 = 1.865 T and P1.7/50 = 1.124 W/kg, which met the requirement of 27Q120.
