摘　　要：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。The effect of 0.35 mm cool rolled plate high grade non-oriented electric steel（mass fraction 2.6% ~2.8%）annealing at 800~900 ℃ by box-furnace on structure,texture and properties was researched.The results showed that with increasing annealing temperature of cool rolled plate,the grain size increased,{111}texture reduced,the best iron loss value was 2.18W/Kg at 900℃,and the magnetic induction was changed unconspicuous,decreased from 1.685 Tat 800 ℃to1.678 Tat 900 ℃.
