1 绪言单取向电工钢板主要用作变压器的铁心材料,磁化性能优良、铁损低是其重要特征。单取向电工钢板含Si约3％,一般是通过二次再结晶,使(110)面与轧制面一致、使〔001〕轴与轧制方向一致,形成所谓的高斯织构而完成其生产过程的。成品板厚对单取向电工钢板的铁损有影响。对于具有完全的二次再结晶组织且晶粒直径和磁感相同的单取向电工钢板来说,一般都是随着板厚的减薄。涡流损失减少,从而使总铁损也减少。板厚进一步减薄到某一
1 Introduction Unidirectionally oriented electrical steel is mainly used as the core material of the transformer, excellent magnetizing performance, low iron loss is an important feature. Uni-directional electrical steel containing about 3% Si, usually through secondary recrystallization, so that the (110) surface and the rolling surface, so that the [001] axis and the rolling direction of the same, the formation of the so-called Gaussian texture and complete its production Process. Finished thickness of unidirectional electrical steel sheet has an impact on iron loss. For uni-directional electrical steel sheets with a completely secondary recrystallized structure and the same grain diameter and magnetic induction, thickness reduction is generally followed. Eddy current loss decreases, so that the total iron loss is also reduced. Thickness further reduced to a certain thickness
