摘要
为了探索退火过程中张力对高牌号无取向硅钢磁各向异性的影响,利用MULTIPAS模拟Fe-3.0%Si无取向硅钢连续退火过程中单位张力变化对硅钢磁性能及磁各向异性影响规律。结果表明,单位张力从2提高到6MPa,铁损P1.5/50和磁感应强度B50各向异性分别由10.50%、1.72%增大到11.11%、1.84%;单位张力为4 MPa时硅钢铁损最低为2.17W/kg;单位张力为3.16MPa时硅钢可以获得较好的磁性能及铁损各向异性;连续退火过程中最佳单位张力应控制在3~4MPa。
In order to explore the effect of tension on magnetic anisotropy of high grade non-oriented silicon steel during annealing,the influence of unit tension on magnetic properties and magnetic anisotropy of Fe-3.0% Si non-oriented silicon steel during continuous annealing was simulated by MULTIPAS.The results show that the anisotropy of iron loss P1.5/50 and magnetic induction B50 increases from 10.50% and 1.72% to 11.11% and 1.84% respectively when the unit tension increases from 2 to 6 MPa;the lowest loss of silicon steel is 2.17 W/kg when the unit tension is 4 MPa;the better magnetic properties and iron loss anisotropy can be obtained when the unit tension is 3.16 MPa;and the anisotropy of silicon steel can be obtained during continuous annealing.The optimum unit tension should be controlled between 3 and 4 MPa.
