综述了退火温度、时间对无取向电工钢磁性的影响。退火温度主要影响无取向电工钢不同织构的占有率,退火时间主要影响晶粒尺寸的大小,晶粒尺寸的变化对织构的形成也有一定的影响。磁感最高点出现在纤维组织完全消失,(111)面织构组分较弱的组织状态。铁损的降低主要依赖于磁滞损耗的降低,织构的影响不大。 The effects of annealing temperature and time on the non-oriented electrical steel magnetic properties were reviewed.Annealing temperature and time mainly affects the different textures share and the grain sizes of non-oriented electrical steel respectively.Changes of the grain sizes also have a certain effect on textures formation.The highest point of the magnetic induction value in the fibrous tissue completely disappears and{111} plane texture has a lower state of the component content.Iron l...
