The grain oriented silicon strip was rolled by cross shear rolling (CSR) and then annealed to manufacture non-oriented thin silicon strip of high quality. The recrystallization of rolled grain-oriented silicon steel into non-oriented silicon steel was studied. For this purpose, CSR is better than conventional rolling, and the higher the mismatched speed rate is, the better the properties of the non-oriented thin silicon strip are. The optimum annealing schedule is heating at 1 000 ℃ for 1 h in pure hydrogen atmosphere added with H2S of 0.001 0 %.
