Analyses of magnetic properties fluctuation in conventional grain oriented silicon steels containing copper

  • 摘要: 含铜取向硅钢是一种成本低、成品率高的新型CGO取向硅钢.其制备工艺明显区别于主流的低温加热渗氮高磁感(HiB)取向硅钢,其产品的磁性能波动范围显著高于低温渗氮钢.本文对实际生产中收集到的一些含铜CGO钢成品板中的组织与磁性能进行研究分析,尝试建立不同组织和磁性能相互间的对应关系,并对磁性能波动现象进行分析.分析结果表明,含铜CGO钢成品板组织与抑制剂有明确的对应关系,而晶粒尺寸与Goss晶粒取向度并不完全呈对应关系.同时对热轧板中的异常组织进行了深入研究,认为热轧板表层脱碳区和中心层粗大形变晶粒的存在,直接影响了抑制剂的分布,导致最终成品板中组织和磁性能的波动.
    Abstract: The conventional grain-oriented (CGO) silicon steel containing copper is a type of grain-oriented steel with low cost and high productivity. The processing parameters in CGO steels are quite different to those of low temperature heating and nitriding high permeability (HiB) grain oriented silicon steels, the fluctuation range of the magnetic properties in CGO is much higher than that of nitrided HiB steels. In this study, typical final sheets from production lines of CGO steels containing copper during early stage production were collected, and the structure, texture, and magnetic properties were determined and compared to establish a relationship between the structure of the steels and inhibitors and to elucidate the reasons for property fluctuation. The results indicate that the macrostructure in the final sheets has a relationship with inhibitors and that the grain sizes do not show monotonous behavior. In addition, the defective microstructure in hot-rolled bands and intermediately annealed sheets are investigated and a coarse grain region and a decarburized surface layer are observed. Such regions are considered to influence the inhibitor distribution and impact the fluctuation in structure and its properties.
