【摘要】 在正交实验基础上,研究磁场退火工艺对成分为3％Si 的0．5mm 厚无取向硅钢微观组织的影响。实验结果表明：退火温度是影响无取向硅钢晶粒尺寸的最主要因素,其次是保温时间与磁场强度。在磁场退火时,随着退火温度的升高、保温时间的延长,晶粒尺寸有长大的趋势；同时磁场能够提高晶粒的均匀性。当施加的磁场强度为 1T、退火温度800℃、保温时间60 min 时, 晶粒尺寸达到最大。更多还原

【Abstract】 The effects of magnetic annealing on microstructure of 0.5mm 3%Si non-oriented silicon steel were studied by means of orthogonal experiment.The results show that:the annealing temperature is the prior factor that affects the grain size of non-oriented silicon steel.Other factors are including holding time and intensity of magnetic field.When magnetic induction is constant,the grain size increases and become more uniform With the further increasing of annealing temperature and holding time.Meanwhile,the magnetic induction could make the grain size more uniform.The grain size of non-oriented silicon steel become maximum while intensity of magnetic field is 1T with annealing temperature being 800℃ as well as holding time is about 60 min.更多还原
