本专利是关于沿钢板的轧向具有易磁化轴<100>,即所谓单取向电磁钢片的制造方法。因为单取向电磁钢片作为软磁材料,主要作为变压器及其它电气设备的铁心使用的,作为磁性指标励磁特性和铁损特性必须良好。最近变压器等电气设备的小型化正成为突出的问题,为此,有必要使铁心重量减少。一般为了把电器设备的铁心重量减少,不得不使用高磁感强度,若以励磁特性良好的即
This patent relates to a method of manufacturing a so-called unoriented magnetic steel sheet having an easy axis of magnetization <100> along the rolling direction of the steel sheet. Because the unidirectional magnetic steel sheet as a soft magnetic material, mainly used as the core of transformers and other electrical equipment, as a magnetic indicator excitation characteristics and iron loss characteristics must be good. The recent miniaturization of electrical equipment such as transformers has become a prominent issue, so it is necessary to reduce the weight of the core. Generally, in order to reduce the weight of the core of electric equipment, it is necessary to use a high magnetic induction. If the excitation characteristic is good
