Effect of normalizing temperature on texture and magnetic property of hot-rolled non-oriented silicon steel

The hot strips normalized at different temperatures were investigated by optical microscope and EBSD to study the effect of normalizing temperature on microstructure and texture of hot-rolled non-oriented silicon steel sheets. The results show that the grain size increases, the intensity of α-fibre texture increases, and the γ-fibre texture decreases when the hot strips are normalized at the 700-850°C. And CSL boundaries of Σ=3 and 15, and misorientation angles between 30° and 55° are more likely related to the growth of Goss grains, by comparative studying the CSL boundary and misorientation distribution for the hot strips normalized at 800-850°C.
