摘　　要：分析了不同的冷弯曲工艺的冷轧无取向硅钢(%:0.003C,0.80Si,0.28Mn,0.015P,0.003S,0.24Als)经750℃2 h去应力退火后的组织和性能。结果表明,再结晶晶粒弯曲变形后,去应力退火过程表面晶粒的长大使钢板中的不利{111}面织构明显减弱,{111}<1 12>织构组分也不再突出;还出现了一定量有利的Goss({110}<001>)织构。该弯曲20次工艺既能改善冲压性能,又提高去应力退火后电磁性能。The microstructures and textures in final products of the non-oriented silicon steel(0.003% C,0.80% Si,0.28% Mn,0.015% P,0.003% S,0.24% Als) with different cold bending process and stress-relief annealing at 750 ℃for2 h are determined and analyzed.The results show that the preferred nucleation and preferred growth of new grains at surface in stres-relief annealing strongly reduce the detrimental {111} texture,particularly the {111} <112> texture component is not predominant and the beneficial Goss texture of {110} <001> is promoted.The proposed bending 20 times working process can improve both formability and magnetic properties of stress relief annealed sheet products.
