采用异步轧制将经过一次正常冷轧和中间退火的 0 .75 m m厚的工业取向硅钢板材异步冷轧至不同的厚度 ,然后进行工业退火 ,研究剪切变形方式对板材织构和磁性的影响。结果表明 :异步轧制下 ,作用于搓轧区上的剪切应力能够有效地改善板材心部的织构组态 ,并在板材亚表层附近相对较大的区域内形成了理想的冷轧织构 ;退火后板材内重新形成了取向集中的 Goss织构 ,其磁性均不低于常规轧制。
Asynchronous rolling was used to cold-roll 0.75mm-thick industrial-oriented silicon steel sheets after normal cold-rolling and intermediate annealing to different thicknesses and then industrial annealing to study the effect of shear deformation on the texture and magnetic properties of the sheets . The results show that under the condition of asynchronous rolling, the shear stress acting on the rubbing-rolling zone can effectively improve the texture configuration of the heart of the sheet and form an ideal cold-rolled texture in a relatively large area near the subsurface of the sheet The Goss texture with concentrated orientation was reformed in the sheet after annealing, and its magnetic properties were not lower than that of conventional rolling.
