摘要/Abstract

摘要： 以工业生产的2.8%Si+1.0%Al无取向硅钢热轧板为试验材料,研究了常化工艺对新能源汽车驱动电机用无取向硅钢组织、织构和磁性能的影响。结果表明:常化处理能够消除热轧变形组织,提高组织均匀性,从而改善冷轧退火组织。随着常化温度的升高,常化板晶粒尺寸和退火成品晶粒尺寸均不断增大;常化能显著改善热轧织构,常化温度升高,{110}和{100}织构强度增加,{111}织构强度减弱,且常化织构具有遗传性,退火成品中{111}织构强度同样会随着常化温度的升高而减弱。热轧板经过900 ℃×4 min常化后,冷轧至厚0.27 mm,并在1000 ℃下退火2 min,退火成品板晶粒尺寸为117 μm,为最佳晶粒尺寸。此时,退火板的磁性能达到最优,铁损P_1.5/50为2.044 W/kg,铁损P_1.0/400为13.368 W/kg,磁感应强度B₅₀为1.672 T。

Abstract: Effect of normalizing process on microstructure, texture and magnetic properties of non-oriented silicon steel for electric vehicle drive motors was investigated by taking industrial produced 2.8%Si+1.0%Al hot rolled plates as experimental materials. The results show that the hot rolled deformation microstructure is eliminated and the microstructure uniformity is improved by normalizing. Thereby the cold rolled and annealed microstructure is improved. The grain size of both normalized and annealed plates continues to increase with normalizing temperature increasing. Besides, the hot rolled texture is improved significantly by normalizing. {110} and {100} textures are strengthened, while {111} texture is weakened, with the increase of normalizing temperature. Due to the heritability of normalized texture, the {111} texture intensity in the annealed plate also weakens with the normalizing temperature rising. After normalizing at 900 ℃ for 4 min, cold rolling to a thickness of 0.27 mm and annealing at 1000 ℃ for 2 min, the grain size of the annealed finished plate is 117 μm, which is the optimal grain size. At this time, the magnetic properties of the annealed plate are the best, with the core loss P_1.5/50 of 2.044 W/kg, the core loss P_1.0/400 of 13.368 W/kg, and the magnetic induction intensity B₅₀ of 1.672 T.
