本发明是叙述单取向硅钢板(带)的处理方法,特别是关于箱式退火的处理方法的。对单取向硅钢板(带)的性能要求是高磁感和低铁损。最近变压器等电器设备重要的趋势是小型高性能化。因此,必须减轻铁心的重量。通常要减轻电器设备的铁心重量,又必须选择磁感强度高的点来使用,故必须用磁性优良的即磁感B_8较高的电磁材料。
The present invention is directed to a method of treating unoriented silicon steel sheets (tapes), and more particularly to a box annealing process. The performance requirements of the unoriented silicon steel (strip) are high magnetic induction and low iron loss. Recently, the important trend of electrical equipment such as transformers is small and high-performance. Therefore, we must reduce the weight of the core. Usually to reduce the weight of the core of electrical equipment, but also must choose the point of high magnetic induction to use, it must be good magnetic properties of the magnetic induction B_8 higher electromagnetic materials.
