发明的详细说明本发明是关于生产(110)[001]取向度良好的并且钢中的ΣO(总氧量),ΣN(总氮量)等杂质较少的取向硅钢板的制造方法。以前,认为在硅钢中添加A1N等氮化物对发展二次再结晶、制造取向硅钢板是比较合适的,但在这个方法中,用A1N做为抑制剂,采用二次冷轧法(冷轧压下率为70％或50％)生产取向硅钢板时,是不能得到B_8>1.85Wb/m~2性能的。而且,在特公昭33—4710号公报
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a grain-oriented silicon steel sheet having (110) [001] good orientation and having less ΣO (total oxygen) and ΣN (total nitrogen) in the steel. In the past, it was considered appropriate to add a nitride such as A1N to the secondary recrystallization for the production of oriented silicon steel, but in this method, A1N was used as the inhibitor and a secondary cold rolling method Down 70% or 50%) can not get B_8> 1.85Wb / m ~ 2 performance when producing oriented silicon steel plate.
