S and low temperature slab reheating in 650~1050 ℃ high temperature annealing process has been studied by orientation distribution function and metallographic observation. Results show that the primary and secondary recrystallization temperature of the grain-oriented Si steel are 650~700 ℃ and 1000~1050 ℃ respectively; the intensity of main texture in primary recrystallized steel decreases in order of{111}

and the grain size and intensity of texture in primary recrystallized structure change slightly at 700~900℃
