In the present work, the effect of pre-annealing on the recrystallized texture of hot-rolled Fe-1.6 wt% Si non-oriented electricalsteel was investigated. Vickers hardness test, optical microscope, and electron backscatter diffraction were used to investigatethe changes in the average hardness, microstructure, and texture caused by pre-annealing of hot-rolled strips. It was found thatthe texture successively changed from a near-random distribution to {116} < 151 > texture and near-{001} < 140 > texturedepending on pre-annealing treatments. Also, there was almost no effect on the grain size, and the average grain size of thenormalized bands was 125 μm. Besides, the texture and magnetic properties of the final products under different pre-annealingtreatments were also detected. It was found that the sample obtain a strong Cube texture by pre-annealing. Meanwhile, themagnetic properties are also got an improvement by pre-annealing. In a word, this method may provide a possibility to obtainan ideal grain size and texture simultaneously.
