本发明系尽可能减少单取向电磁钢板中的残余应力,即基本上没有残余应力,从而不经消除应力退火也能具有优良电磁特性的电磁钢板的制造方法。众所周知,为了使单取向电磁钢板具有发达的高斯方位,都需在间歇式炉中于1100℃以上进行高温退火,然而经上述高温退火后的带钢板形变坏,因此一般在高温退火后还需进
The present invention is a method of manufacturing an electromagnetic steel sheet having as little residual stress as possible in the grain-oriented electrical steel sheet, that is, having substantially no residual stress, so as to have excellent electromagnetic characteristics without stress relief annealing. It is well known that in order to make the grain orientation of a grain-oriented electrical steel sheet to have a developed Gaussian orientation, it is necessary to perform high-temperature annealing in a batch type furnace at a temperature of 1100 ° C or higher. However, the shape of a steel strip after high-temperature annealing deteriorates. Therefore,
