研究了不同工艺生产的低温取向硅钢热轧板中第二相粒子的析出行为及其组织。结果表明，热轧板中的析出物除了弥散分布的纳米级球形或椭球形的 MnS、Cu2 S 外，还观察到与其形貌相似的 SiO2、AlN 和 Si3 N4及其复合在一起的复杂化合物。试样中微米级析出物主要为 SiO2、MnS、Cu2 S 和 AlN 的复合物，纳米级析出物主要为 AlN、Si3 N4、MnS、Cu2 S 的复合物。热轧板中0．01～0．2μm 的析出物数量最多，约占总数的99％。与常规热轧板相比，CSP 试样中夹杂物面积密度较小，在大于1μm 范围内其平均尺寸较大，会使得后期退火过程中二次再结晶不完整，影响产品磁性能。热轧板在垂直于轧向横截面上组织分布具有很大的差别，其中 CSP 试样组织相对比较均匀，不利于后续处理工艺中发展完善的二次再结晶织构从而获得良好的磁性能。

The precipitation behaviors of the second phase particles and their textures in the low temperature grain‐oriented silicon steel are studied under different processes.The results show that not only the dispersed nanoscale spherical or ellipsoidal MnS and Cu2 S precipitations are observed in the hot rolled slabs,but also SiO2 ,AlN and Si3 N4 which are similar to MnS and Cu2 S in the morphology and complex compounds that are composed by them together are observed.In the sample,precipitations at the micron scale are mainly composed by SiO2 ,MnS,Cu2 S and AlN,and precipitations at the nanoscale are mainly composed by AlN,Si3 N4 ,MnS and Cu2 S.The number of precipitates whose size is from 0.01 μm to 0.2 μm is the largest in the hot rolled slabs,which accounts for about 90%.Compared with the conventional hot rolling slabs,the area density of the inclusions in the CSP samples is smaller,but the average size in the range of greater than 1 μm of that is larger.It will make the secondary recrystallization incomplete during the annealing process,and also it can influence the magnetic property of the products.The distribution of texture which is perpendicular to the rolling direction on cross section in the hot rolled slabs is very different.The texture of the CSP samples is relatively uniform,which is harmful to develop complete secondary recrystallization texture during the subsequent treatment process to obtain good magnetic properties.
