摘要：
Effect of annealing stresses on the magnetic properties of non-oriented electrical steel has been studied. When the annealing stress increases from 2.5 to 4.5 MPa, the iron loss P1.0/400 of non-oriented electrical steel increases from 14.28 to 15.29 W/kg, the anisotropy index T raises from 17.0 to 22.0 pct, the magnetic induction B5000 decreases from 1.656 to 1.646 T. This is mainly due to the amount of MnS-containing precipitates increases with the increasing of the annealing stress.
