Effect of normalizing temperature on the microstructure,texture and magnetic properties of 3.2wt％Si high magnetic induction orientation(Hi-B)silicon steel was studied by means of EBSD technique and single-chip measurement method.The results show that with the increase of normalizing temperature,the columnar grains of the normalized plate are completely recrystallized,and the texture types are similar to ot texture,λ texture and Goss texture.After decarburizing annealing,the texture mainly consists of { 114}<481>,γ texture and Goss texture,and the primary recrystallized grain size increases first and then decreases with the increase of normalizing temperature(maximum at 900 ℃,up to 20.3 μm).After normalizing annealing at 850 ℃,the area fractions of { 114 }<481>texture and Goss texture,which are beneficial to magnetic properties,reach the highest(26.1％and 4.5％,respectively)in the primary recrystallized specimen.When the normalizing temperature is 850 ℃,the Hi-B steel can obtain the best magnetic properties,B8=1.938 T,P1.7/50=0.828 W/kg.
