Development of Secondary Recrystallization in high permeability grain oriented Silicon steel produced by Thin Slab Casting and Rolling process

Texture evolution during high temperature annealing process in high permeability grain oriented(Hi-B) silicon steel produced by Thin Slab Casting and Rolling(TSCR) process was investigated using macro-/microtexture analysis. Goss texture appears in ODF at 800 degrees C, the intensity of Goss texture is very weak until 950 degrees C;Goss grains grow abnormally during 980 degrees C similar to 1000 degrees C, grain size reached centimeter level at 1000 degrees C, Goss grains instead of Primary grains fully at 1020 degrees C, Secondary Recrystallization completed at 1040 degrees C; The deviation angle of Goss grain orientation decreases gradually with temperature increasing, and it reached the minimum at 1040 degrees C.
