Effects of heat treatment process on microstructure and iron loss of 0.25% Si non-oriented silicon steel sheets containing niobium

  • 摘要: 向无取向硅钢中添加适量的铌元素,可以有效改善成品钢的显微组织和机械性能,但会对电磁性能产生不利影响。截至目前,尚不清楚铌元素在无取向硅钢中的存在形式、作用机理,以及在不同热处理工艺条件下对电磁性能的影响效果。研究结合0.25% Si含铌无取向硅钢生产实际,探讨了铌元素在钢中的存在形式、作用机理和影响效果,并借助热处理工艺优化以减轻铌元素对钢电磁性能的影响。结果表明,铌元素在钢中会形成百纳米级、数量众多的有害夹杂物,钉扎晶界和降低晶界扩散率,并推迟钢的再结晶开始温度和结束温度,因而,导致晶粒细化和铁损升高。随着钢中铌含量增加,钢的涡流损耗基本相当,但磁滞损耗不断增加。合理的热处理工艺,可以促进消除应力退火之后的晶粒尺寸长大,并在一定程度上减少磁滞损耗之间的差异。
