The normalized 2.2 mm plate of non-oriented silicon electric steel(0.004C

3.1Si

0.33Al)was rolled to 0.5 mm sheet by asynchronous rolling process with a rate of 1.19

and the evolution of asynchronous cold rolling texture in thickness direction was investigated quantitatively by orientation distribution function (ODF) mehtod. Results showed that there was an obvious change of texture in thickness direction of normalized plate of non-oriented silicon electric steel:the anti-Gaussian texture was stronger close to center of thickness which was kept even after asynchronous cold rolling

but the Gaussian texture at surface and sub-surface of sheet disappeared after cold rolling; there was no change of texture type along slow and fast roller side

but the intensity of texture changed obviously; the distribution of asynchronous cold rolling texture was non-symmetric; the anti-Caussian texture in slow roller side was higher than that in fast roller side

the{111}〈112〉texture was low at center and high at sides which at slow roller side was little higher than that at fast roller side.
