采用取向分布函数分析了无取向电工钢不同再结晶退火温度下的织构变化及织构对磁感应强度和铁损的影响,并计算了无取向电工钢的磁晶各向异性能。结果表明,随着实验钢的再结晶退火温度升高,Goss织构和立方织构组分显著增强,而{111}面织构强度却减弱。较高的退火温度有利于减小织构因子,提高磁感应强度。磁晶各向异性能计算结果显示,随着再结晶退火温度升高,无取向电工钢板的磁晶各向异性能降低。
The orientation distribution function was used to analyze the texture changes of the non-oriented electrical steel at different recrystallization annealing temperatures and the effect of texture on the magnetic induction and iron loss. The magnetocrystalline anisotropy of the non-oriented electrical steel was calculated. The results show that with the increase of recrystallization annealing temperature, the Goss texture and cubic texture components increase significantly, while the {111} texture strength decreases. The higher annealing temperature helps to reduce the texture factor and improve the magnetic induction. Magneto-crystal anisotropy calculation results show that with the recrystallization annealing temperature increases, non-oriented electrical steel magnetocrystalline anisotropy can be reduced.
