The results show that the nonuniform microstructures of hot rolled strip play an important role in developing the perfect secondary recrystallization. Fe-3.15% Si steel is rough rolled at 1110°C, finished rolled at 880°C, subsequently cooled to 550°C for coiling at rate of 10°C/s, then air cooled to room temperature. The above mentioned process could produce hot-rolled microstructure which are benefit to formation of Goss texture and the development of perfect secondary recrystallization.Read More
