摘要
对27AHSW450高强度无取向硅钢进行了不同工艺制度常化实验。结果显示,经900~1030℃常化50 min后,950℃才可观察到几乎完全回复和再结晶的等轴晶。取向由近热轧板织构分布特征向随机取向的织构过渡。经950℃终退6 min后,成品板中织构分布趋于一致,主要由λ织构、α*织构和强γ织构组成。成品的轧向磁感应强度优于横向。900℃常化时磁感应强度最佳值为1.64 T。横向和纵向的铁损差异不大,950℃常化时铁损值最低,为25.1 W/kg。
Different normalization annealing experiments were carried out on 27AHSW450 high-strength non-oriented silicon steel.The results showed that equiaxed crystals with almost complete recovery and recrystallization were observed at above 950℃after normalized at 900~1030℃ for 50 minutes.The distribution of texture transferred from hot-rolled sheet texture to randomly oriented texture.After final annealing at 950℃for 6 minutes,the texture distribution in the final annealing sheet tended to be consistent,mainly consisting of λ fibre texture,α*fibre texture and strongγfibre texture.The magnetic induction of rolling direction was better than that of transverse direction.The highest magnetic induction value was 1.64 T when normalized at 900℃.The core loss differed a little in rolling direction and transverse direction.The lowest iron loss value was 25.1 W/kg when normalized at 950℃.
