摘　　要：磁屏蔽纯铁材料新品需满足更高磁性能要求,本研究开发了最大磁导率为0.037 1 H/m,矫顽力为14 A/m的磁屏蔽用高磁导率电磁纯铁,研究了化学成分、磁性热处理工艺对电磁纯铁晶粒大小和磁性能的影响。结果表明：高Al含量可提高磁性热处理温度,使磁性热处理后的晶粒增大,从而提高最大磁导率,降低矫顽力;磁屏蔽用高磁导率电磁纯铁合适的磁性热处理温度为1050~1150℃。Development of magnetic shielding pure iron requires higher magnetic properties. In this paper, we develop a high permeability magnetic Iron for magnetic shielding. Its permeability is 0：037 1 H/m and coercivity is 14 A/m. Effects of chemical composition and magnetic heat treatment on grain size and magnetic properties are researched. The results show that high aluminum content earl increase magnetic heat treatment temperature, enlarge the grain size, then increase maximum permeability and reduce coercivity; the ideal magnetic heat treatment temperature of high permeability magnetic Iron is 1050~1150 ℃.
