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 orientation distribution function and orientation line analysis method were used to study the texture of low temperature slab heated oriented silicon steel from hot rolling to primary recrystallization. The results show that there is an inheritance relationship between texture components of each layer and texture components of each layer of the hot-rolled sheet after primary cold rolling, and there is a strong {001} <110> texture in the subsurface layer. Similar to the central layer of hot rolled sheet, there are strong {001} <110> and {112} <110> textures. Recrystallization occurs after the intermediate annealing, and the strength of the textures is weakened. The Goss textures The texture of {111} <112> has the highest texture intensity, which is nearly double that of other texture components. {001} <110> The texture is greatly reduced; the texture has no significant inhomogeneity along the thickness direction after the first recrystallization, {111} <110> is the strongest texture component and has a certain Goss orientation.
