摘要
研究了罩式退火工艺的升温速率对0.8%Si无取向硅钢组织、织构及磁性能的影响。结果表明,经过不同升温速率退火后,无取向硅钢的再结晶织构主要为{111}织构,伴随有{110}、{100}织构。随着退火升温速率的提高,晶粒尺寸逐渐增大,{111}织构明显减弱,{110}织构明显增强,{100}织构没有明显变化,铁损P_(1.5/50)逐渐降低,磁感应强度B_(5000)逐渐增强。但当升温速率由80℃/h升高至100℃/h时,{111}织构出现一定程度的增强,{110}织构出现减弱,{100}织构没有明显变化,铁损P_(1.5/50)增大,磁感应强度B_(5000)减小。在退火升温速率为80℃/h时,无取向硅钢可获得最优的磁性能:P_(1.5/50)=4.249 W/kg,B_(5000)=1.715 T。
Effect of heating rate on microstructure, texture and magnetic properties of 0.8%Si non-oriented silicon steel during bell annealing process was studied. The results show that after annealing with different heating rates, the recrystallized texture of the non-oriented silicon steel is mainly {111} texture, accompanied by {110} and {100} texture. With the increase of heating rate, the grain size gradually increases, the {111} texture appears to be significantly weakened, the {110} texture appears to increase significantly, and the {100} texture does not change significantly, meanwhile, the iron loss P_(1.5/50)gradually decreases, and the magnetic induction intensity B_(5000)gradually increases. However, when the heating rate is increased from 80 ℃/h to 100 ℃/h, the {111} texture appears to be strengthened to a certain extent, the {110} texture appears to weaken, and the {100} texture does not change obviously, moreover, the iron loss P_(1.5/50)increases and the magnetic induction intensity B_(5000)decreases. When the heating rate of bell annealing process is 80 ℃/h, the optimum magnetic properties can be obtained as P_(1.5/50)=4.249 W/kg, B_(5000)=1.715 T.
