采用取向分布函数和取向线分析方法对低温板坯加热取向硅钢从热轧到初次再结晶工艺阶段的织构进行了研究。研究表明:一次冷轧后各层的织构组分与热轧板各层面的织构组分存在着继承关系,次表层存在很强的{001}<110>织构,中心层的织构和热轧板的中心层相似,存在强的{001}<110>和{112}<110>织构;中间退火后发生再结晶,各织构组分的强度有所减弱,Goss织构组分再次出现;二次冷轧后沿厚度方向上的织构不均匀性不明显,{111}<112>织构强度最高,几乎是其他织构组分的1倍,{001}<110>织构大幅降低;初次再结晶后织构沿厚度方向没有明显的不均匀性,{111}<110>为最强的织构组分,并且具有一定强度的Goss位向。

The texture from the first cold rolling to the primary recrystallization of low temperature slab reheating grain-oriented electrical steel were researched by orientation distribution function and orientation distribution intensity technique. The results show that after the first stage of cold rolling, there is a strong {001}<110> texture in the subsurface and the texture in center layer is very similar to the center layer of hot band which has strong {001}<110> and {112}<110> texture, due to the heredity. After intermediate annealing the microstructure indicates full recrystallization throughout the sheet thickness. Additionally, the strength of each texture is weakened and the Goss orientation reappears in all layers. There was very little through-thickness variation of the texture after the second stage of cold rolling, exhibiting major {111}<112> and minor {001}<110> components. After primary recrystallization the texture are qualitatively similar from all layers with the {111}<110> is strongest and a certain intensity of Goss texture.
