摘要/Abstract

摘要： 通过一次冷轧法对低温取向硅钢进行了250 ℃、不同时间的时效轧制试验,研究了时效轧制对低温取向硅钢组织、织构及磁性能的影响。结果表明,时效轧制对低温取向硅钢的冷轧及初次再结晶组织没有明显的影响,但可以显著改善初次再结晶织构;随着时效时间延长,初次再结晶组织中有利的Goss织构和{111}<112>织构含量先增加后降低,5 min时含量达到最高。有利织构含量增加可以改善二次再结晶组织,提高成品板的磁性能。成品板的磁感应强度随着时效时间的延长先增加后减小,铁损呈现相反的趋势,在时效轧制时间为3~7 min时,成品板具有优异的磁性能。

Abstract: Effect of aging rolling on the microstructure, texture and magnetic properties of the low-temperature oriented silicon steel was studied by conducting aging rolling tests at 250 ℃ for different time using a single cold rolling method. The results indicate that the aging rolling has no significant effect on the cold rolling and primary recrystallization microstructure of low-temperature oriented silicon steel, but it can significantly improve the primary recrystallization texture. The contents of favorable Goss and {111}<112> textures in the primary recrystallization microstructure increase first and then decrease with the increase of aging rolling time, reaching the maximum value at 5 min. An increase in favorable texture content can improve the secondary recrystallization microstructure and enhance the magnetic properties of the final sheet. The magnetic induction intensity of the final sheet increases first and then decreases with the prolongation of aging rolling time, and the iron loss shows the opposite trend. When the aging rolling time is 3-7 min, the final sheet has excellent magnetic properties.
