| 摘 要： | 摘 要： 为了获得磁性能优良的高牌号无取向硅钢，系统地研究了稀土铈对2.9%Si无取向硅钢中夹杂物的变质及粗化，退火板的组织、织构及磁性能的影响规律。结果表明：钢中添加适量（质量分数0.005 5%）的铈能使夹杂物聚集粗化，最终使成品再结晶晶粒尺寸增大，有利织构组分{100}和{110}面织构增多，不利织构组分{111}面织构减少，磁性能达到最佳。但是当铈添加过量（质量分数0.019%）时，其作用反而相反。

| Abstract: | In order to obtain high grade non-oriented electrical steel with excellent magnetic properties, the effect of Ce on the formation of inclusions, microstructure, texture and magnetic properties of 2.9%Si non-oriented electrical steel was investigated in depth and systematically. The results show that the proper content of Ce (0.005 5%) could make the inclusions in steel aggregated and coarsened. Therefore, the recrystallized grain size increased together with {100} and {110} texture component, and {111} texture component decreased. Under this condition, the magnetic properties reached an optimal value. However, when an excessive amount of Ce (0.019%) was added, all the effects would become opposite. |
