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.展开更多
