The evolution of microstructure,texture,and magnetic properties with random texture,near-copper texture,weak near-cube texture,and strong λ fiber(＜001＞//ND(normal direction))before rolling of non-oriented electrical steel was studied.Three recrystallized hot bands with different textures but similar grain sizes were prepared by pre-annealing at low-temperature and high-temperature normalization annealing.It was observed that the final annealed products exhibited similar recrystallized microstructures.By contrast,the final annealed product with more λ fiber before rolling exhibited a stronger cube texture.With the λ fiber before rolling becoming stronger,the proportion of {111}＜110＞deformed matrices became larger,which could be observed in the early recrystallization stage.The overwhelmingly dominant λ orientation nuclei are formed in the {111}＜110＞deformed matrix and become the dominant texture.Eventually,the best magnetic properties are obtained in the products with strong λ fiber before rolling,corresponding to the strong cube texture and low anisotropy parameter.
