Abstract: The recrystallization texture of non-oriented electrical steel under different annealing stress was investigated by orien-tation distribution function analysis. The result showed that the size of the recrystallization grain increased with the increase of annealing tension. When annealing tension was 4 MPa, the average diameter of grain reached the maximum of 75 μm with even size,and Goss texture and cube texture component were enhanced,as P1.5/50 was reduced to 4.34 W·kg-1 and B50 increased to 1.684 T. When annealing tension increased to 6 MPa, the grain size would decrease to 40 μm,leading to the decrease of intensity of {110}〈001〉 and {001}〈100〉texture, the increase of density of {111} fiber and the visible deterioration of magnetic property.
