对高牌号无取向硅钢进行异步轧制,然后在不同时间下进行再结晶退火,研究异步轧制条件下高牌号无取向硅钢再结晶织构随退火时间的演变过程,探讨高牌号无取向硅钢再结晶织构的形成及再结晶织构组分与磁性的关系。结果表明:在750℃再结晶退火过程中,随着退火时间的延长,α织构强度减弱,织构组分逐渐向{111}〈112〉附近聚集,铁损逐渐下降。快慢辊侧再结晶织构类型基本相同,但慢辊侧强度高于快辊侧。 The high grade non-oriented silicon steel was subjected to asynchronous rolling and then recrystallization annealing at different times to study the evolution of recrystallization texture of high grade non-oriented silicon steel with annealing time under asynchronous rolling conditions, Formation of Crystalline Texture and Relationship between Recrystallization Texture and Magnetic Properties. The results show that the strength of α decreases with the annealing time prolonging and the texture components gradually gather near {111} <112>, while the iron loss decreases gradually. The type of recrystallized texture on the roll side is almost the same, but the strength on the slow roll side is higher than on the fast roll side.
