针对新日铁公开的相关专利,总结日本高强度无取向电工钢的研究进展,分析了各专利化学成分、生产工艺及产品性能的特点,指出固溶强化、细晶强化、析出强化、位错强化都有可能被用来提高无取向电工钢的强度。在高强度无取向电工钢的研发过程中,需要根据其具体用途确定目标性能,再采用合适的强化手段,从而实现力学性能、磁性能和生产性能之间的平衡。 Authors summarize the research progress of high strength non-oriented electrical steel in Japan by learning related patents brought into the public by Nippon Steel. Authors also analyze the characteristics of the chemical composition, production technology and properties of products in the patents and point out that any ones of solution strengthening method, fine-grain strengthening method, precipitation strengthening method or dislocations strengthening method may be used to improve the strengt...

通过实验室25 kg真空感应炉冶炼和锻轧研究了0.26%～0.95%Al含量对0.5 mm 2.2%Si无取向硅钢冷轧板组织、织构和磁性能的影响。试验结果表明,0.26%～0.81%Al含量时,随钢中Al含量的增加,成品退火钢板的晶粒尺寸增加同时铁损减少;当Al含量大于0.81%时,随Al含量增加,钢板的晶粒尺寸减小,同时铁损增加。Al含量对硅钢板磁感的影响没有明显的规律。2.2%Si无取向硅钢的合适Al含量为0.48%～0.81%。 The effect of 0.26%～0.95%Al content on structure,texture and magnetic performance of 0.5 mm cold rolled sheet of 2.2%Si non-oriented silicon steel has been studied by a 25 kg vacuum induction furnace smelting,and forging -rolling in laboratory.Results show that as 0.26%～0.81%Al,with increasing Al content in steel the grain size of annealed finished sheet increases while iron loss of sheet decreases,and as Al content in steel is more than 0.81%,the grain size of sheet decreases while iron loss in...
