Abstract：The effect of Ce element on the evolution of recrystallization microstructure and texture in a 2.9%Si-0.8%Al non-oriented silicon steel during annealing process was investigated by using OM，SEM/EBSD technology and OIM analysis software. The effect of Ce on the evolution of initial recrystallization texture，recrystallization texture，recrystallization ratio and grain size of recrystallization was researched respectively. The results showed that the recrystallized grains size and recrystallization ratio of specimens containing Ce were coarser and higher than those of specimens without Ce respectively. The fraction of favourable textures in specimens with Ce during recrystallization was also higher than that in specimens without Ce. Moreover，the fraction of unfavorable {111} face texture in specimens with Ce was less. The main reason is that appropriate Ce in non-oriented electrical steel reduced fine MnS，coarsen and modified Al2O3 and spherified AlN inclusions，this results in more favorable textures appearing in non-oriented silicon steel containing Ce.
