采用异步轧制对经过一次正常冷轧和中间退火的、厚度为0.746mm的工业取向硅钢实施一次速比为1.17的异步冷轧，轧至0.34mm，在普通的工艺条件下，进行退火，用ODF和反极图定量研究各层织构的分布与转化。并测量了磁性。结果表明：在本工艺条件下，织构组分与传统冷轧相同，异步轧制板材的表层附近世出现了类似于正常轧制下位于亚表面层上的，理想的冷轧织构组分，但是已明显地偏向了快速辊侧表面，冷轧织构组态沿着轧板的厚度方向呈现了非对称分布；脱碳退火后，η织构加强，织构组分沿板厚方向上重新出现了以轧板中心面为对称的分布；二次再结晶退火后，产生了强度集中的Goss织构。其磁性能不低于同步轧制。

Commercial grain oriented silicon steels 0 30mm thick were cold rolled to thinner than mm by the cross shear rolling (CSR) and the conventional rolling respectively, then annealed in a normal hydrogen atmosphere furnace. The influence of the process parameters on rolled textures and the magnetic property of thin silicon steel sheets were investigated. The results indicated that the cross shear rolling was beneficial to improve the rolled textures and the magnetic property of the thin silicon steels. The amount of nucleus of Goss grain increased with increasing the mismatch speed ratio; in addition, magnetic properties were improved further with increasing reduction rate, meanwhile, rolled textures tend to well distributed through the thickness of the sheet.
