摘　　要：目前,国内外无取向电工钢用户不仅要求电工钢磁性能良好,对加工性能也提出较高要求。通过测试不同预拉伸状态下材料的白片力学性能及白片、黑片磁性能,对加工强化提高无取向电工钢在供货状态下的屈服强度以及去应力退火解决加工强化磁性能劣化问题进行了一些探索性研究,并对不同状态下材料的残余应力对磁性能的影响进行了分析。Non- oriented electrical steel is required to possess not only excellent electric ＆ magnetic properties but also excellent mechanical properties. By testing the electric ＆ magnetic properties and mechanical properties of white sheets and black sheets under different strains, the author studies the effects of work - hardening on improving the yield strength of white sheets and stress relief annealing on improving the electric ＆ magnetic properties of black sheets. The effects of residual stress on the electric ＆ magnetic properties of non - oriented electrical steel under different conditions are also analyzed.
