采用不同的速比对取向硅钢进行异步冷轧，并在常规的生产条件下进行退火，研究速比对织构转变的影响.结果表明：速比对冷轧样品的表面及靠近快速辊侧的区域影响较小，但对心部的影响较大；速比的增加有利于样品两侧亚表层及心部织构组态的改善；样品在靠近快速辊侧的织构转变中出现了“遗传性”，但对最终的织构和磁性影响不大；二次再结晶退火过程中，Goss织构组分异常长大，成为板材的唯一组分；在不同的速比下，样品最终的晶粒尺寸、织构和磁性基本相同，因此速比可在一定的范围内选择．
The as-cast cold rolled steel was asynchronously cold rolled at different speed ratios and annealed under conventional production conditions to study the effect of speed ratio on the texture change.The results show that the speed ratio is significantly lower on the surface of cold- But the influence on the heart is larger; the increase of speed ratio is beneficial to the improvement of the configuration of the sub-surface and the heart on both sides of the sample; in the texture transition near the fast roll side, the "genetic However, it has little effect on the final texture and magnetic properties. During the secondary recrystallization annealing, the Goss texture grows abnormally and becomes the sole component of the sheet. At different speed ratios, the final crystal Grain size, texture and magnetism are basically the same, so the speed ratio can be selected within a certain range.
