Influence of Annealing Technology on Structure and Texture of Cold Rolled Unoriented Silicon Steel

Considering the annealing technology of cold rolled unoriented silicon steel,the effects of annealing temperature and time on structure and texture were investigated.The results show that the density of {100}texture drops obviously in the α line,grains get together from {112}〈110〉 to {111}〈112〉.And {100}〈hkl〉 texture increased with soaking time.The texture distributed homogeneously and the {001} texture’s occupancy is improved when the steel is annealed at 900 ℃,for 180 s and then water-cooled.
