Through-thickness texture variation in non-oriented electrical steel sheet produced by asymmetric rolling

The hot bands of non-oriented electrical steel were cold rolled by asymmetric rolling with speed ratio of 1.125 as well as conventional symmetric cold rolling to investigate the effects of cold rolling mode on through-thickness texture variation. Asymmetric rolling shows a marked weakening effect on a fiber (RD//< 110 >) running from {001}< 110 > to {112}< 110 > through sheet thickness, especially at the side contacting with faster roll. Asymmetric rolling increases {111}< 112 > component while decreases {111}< 110 > component through sheet thickness except for the surface layers. The through-thickness texture variation due to asymmetric rolling was explained in terms of shear strain distribution.
