摘　　要：研究了CSP工艺流程生产的硅含量为1.5%的无取向电工钢在不同常化温度下对磁性能的变化。研究结果表明:随着常化温度的提高,热轧板的晶粒尺寸增大,且组织均匀性提高;此外成品的有利织构组分{100}<0vw>、α、η增强,不利织构组分减弱;铁损P1.5/50呈下降趋势,磁感B50上升平缓。在常化工艺为970℃×2.5min下,对应的铁损P1.5/50<3.4W/kg,磁感B50>1.74T。The effect of normalizing temperature on the magnetic properties of non-oriented electrical steel contai- ning 1.5 % silicon produced by CSP process was studied. The results show that with increasing normalizing tempera- ture, the average grain size of hot-rolled plate increases and the microstructure uniformity is improved. Furthermore, the texture components of finished products are improved through enhancing of { 100} 〈Ovw〉, α and ηtextures and weakening of { 111} 〈112〉 texture; the core loss P1.5/50 decreases and magnetic induction B50 increases gently. The core loss is less than 3.4 W/kg and magnetic induction more than 1.74 T at the normalizing temperature of970℃ for 2.5 minutes.
