研究了箱式炉800~900℃区间恒温退火制度控制下,对0.35mm厚度规格、硅的质量分数为2.6%~2.8%的无取向高牌号硅钢织构组分及性能的影响。结果表明,随着退火温度的升高,成品晶粒尺寸逐渐增大且均匀性得到改善;{111}织构组分占有率呈现下降的趋势,最佳铁损指标可达到900℃时的2.18 W/kg;磁极化强度变化不显著,由800℃时的1.685T降低到900℃时的1.678T。 Under the control of constant temperature annealing in the range of 800-900 ℃, the effects of the high-grade non-oriented silicon steel texture component with 0.35mm thickness and the silicon content of 2.6% -2.8% The results show that as the annealing temperature increases, the grain size of the finished product increases gradually and the uniformity is improved. The proportion of {111} texture components shows a decreasing trend. The optimum iron loss index can reach 2.18 at 900 ℃ W / kg; magnetic polarization intensity changes insignificantly, from 1.685T at 800 ℃ to 1.678T at 900 ℃.
