在现普通冷轧无取向硅钢的基础上,降低Si含量,复合添加少量辅助元素,组合热轧板处理和成品退火加热技术,研制出了免常化处理的高磁感、低铁损并具有良好耐酸腐蚀性能的新系列无取向电工钢。 Based on existing common cold rolled non-oriented silicon steel,a new series of non-orientedelectrical steel with high induction,low core loss and excellent anti-corrosion property has been developed by reducing Si element,adding complexly a small amount of supplementary elements,and employing combined treatment of hot rolled sheet and finished product annealed heated technology.

对无取向电工钢中的夹杂进行了系统的分析。利用小样电解,采取不同电解液,不同的分离方法对无取向电工钢中稳定和不稳定夹杂物进行了提取、分离和收集。利用扫描电镜(SEM)、X-射线衍射、ICP等对电解分离收集的夹杂物进行了定性和定量分析。 The inclusion analysis of the non-oriented electrical steel has been investigated.By using small sample electrolytic analysis,with different electrolytes and different separation ways,the stable inclusions and unstable inclusions was drew,separated,and collected.With utilizing the methods of SEM,X-ray and ICP,the qualitative and quantitative analysis of inclusions in the non-oriented electrical steel was obtained.
