通过对取向分布函数（ODF）的分析，研究了无取向硅钢热轧板在常化过程中不同厚度位置的织构演变情况。结果表明，热轧板内部在常化过程中发生再结晶，不同位置的织构变化不同，表层处织构变化不明显，各组分混乱分布且强度不高；1/4板厚处热轧板和常化板的高斯织构都比较强，但900 ℃常化后高斯织构强度有所降低；中心层常化前后织构发生明显变化，{111}<112>织构强度增强。
Texture evolution during normalizing process in hot band of nonoriented silicon steel was in vestigated.The result showed that the texture evolution of hot band was different in different layer during normalizing process.The change is small in top layer,the texture is in confusion and the intensity is low.The intensity of Gosstexture is decreased in 1/4 layer after normalizing.There is significant change of texture in the center of hot band after normalizing,the intensity of ｛111｝＜112＞ texture is increased.
