摘　　要：将1J79铁心片放入零件盒中,并加盖零件盒防护盖对铁心片进行退火试验,退火时冷却至600℃后随炉冷却,试样的初始磁导率μ0偏低,而最大磁导率μm偏高。取掉零件盒防护盖,提高退火时冷却600℃后的冷却速度,将炉冷改进为风冷,试样的初始磁导率μ0提高至66.02 m H/m,最大磁导率μm降低至245.29 m H/m,满足了特殊磁性能要求。The 1 J79 1 core piece was put into the part box, and the annealing test of core sheet with part box cover was carried out. When annealing, cooling with furnace be low 600 ℃, the initial permeability μ0 of the specimen is low, while the maximum permeability μmis high. Remove the part box cover, increase cooling rate after annealing to 600 ℃, improve furnace cooling to air cooling, the initial permeability of the specimen μ0 increases to 66.02 m H/m, and the maximum permeability μmdecreases to 245.29 m H/m, which meets the special magnetic properties.
