研究了由平整工艺产生的平整轧制方向对半加工无取向电工钢板的磁性及方向性的影响。平整轧制方向大大地影响了电工钢的磁性得方向性。通过控制平整轧制方向 ,在需要的方向上 ,如 0°、90°及整个圆周方向上 ,可对B50 的大小进行调整 ,并且B50 值高于普通平整 0°轧制方向内B50 的大小。分批退火后 ,钢板的织构随着平整轧制方向的变化而发展 ,该结果表明 ,由平整工艺产生的剩余应变能随着平整轧制方向而变化 The influence of the flat rolling direction produced by the smoothing process on the magnetic and directivity of the semi-machined non-oriented electrical steel sheet was studied. The direction of smooth rolling greatly affects the magnetic directionality of electrical steel. By controlling the rolling direction, the B50 size can be adjusted in the desired directions, such as 0 °, 90 °, and the entire circumferential direction, and the B50 value is higher than the B50 size in the normal 0 ° rolling direction. After batch annealing, the texture of the steel sheet progressed as the direction of the smoothing rolling changed. The results show that the residual strain produced by the flattening process varies with the direction of the flat rolling
