Abstract: The manufacturing flow sheet simulated CSP process o£ narrow strip of Hi-B steel (/% ： 0. 05C, 0. 20Mn, 3. 47Si, 0. 001 5S, 0. 007P, 0. 027Al, 0.006 0N) is 25 kg vacuum induction fumace melting- casting to 40 mm x 85 mm slab ingot- hot-rolling to 2. 5 mm plate- normalizing at 930 °C - cold-rolling to 0. 6 mm (76% ), 0. 4 mm (84% ) , 0. 3 mm (88% ) and 0. 2 mm (92% ) sheet- primary recrystallization-annealing at 830 °C for 5 min. The analysis on texture of priniary recrystallization-annealed specimen has been carried out by X-ray diffractometry (XRD). Results show that after primary recrystallization-annealing, the GOSS texture forms mainly at subsurface and there are some GOSS texture al 1/4 layer of sheet with reduction ratio 76% ; with increasing reduction the intensity of {112} < 110 > and {001}< 110 > orientation of a fiber texture gradually weaken, while the intensity of {111} < 112 > and {111}< 110 > orientation of γ fiber texture orientation first increase and then weaken ； with reduction ratio 88% the γ fiber texture strongly concentrates to {111} < 112 > orientation, the intensity of that reaches to max, it is favourable to form GOSS texture.
