Effect of Temperature on Recrystallisation Texture and Microstructure for Non-Oriented Silicon Steel under Asymmetrically Rolling Process16

Abstract:

The effect of temperature on the recrystallization texture and microstructure of non-oriented silicon steel under asymmetrically rolling condition was quantatively studied using X-ray diffraction technology. The results show that the texture component accumulates around {111}<112> when annealed at 800°C. Texture intensity is high and grain size is uniformly distributed between 50μm and 100μm with best magnetism. When annealed at 850°C and 900°C, texture component is scattered and the grain size is also bigger. However, for the annealing at 750°C, the texture component is similar to cold rolled process. The grain size is small and non-uniform, which is unfavorable to magnetism. The difference of forces along the fast and slow side of the roller results in different deformation texture and further affects the intensity of recrystallization texture along the two sides of the roller.
