借助电子背散射(EBSD)技术对AlN为主抑制剂的Hi-B取向硅钢常化工艺的中间冷却制度进行了研究。结果表明:常化后试样均发生了完全再结晶,在60℃/s冷速下组织最均匀;在合适的冷却制度下常化板表层保留了强的Goss织构,它深入到1/4厚度处,并且形成对Goss织构有利的强{554}<225>织构。 The intermediate cooling system of Hi-B oriented silicon steel with AlN main inhibitor in normalizing process was studied by means of electron back diffraction(EBSD) technique. The results show that:the specimens after normalizing are fully recrystallization, and the microstructure is most uniform under the intermediate cooling rate of 60℃/s; under suitable cooling system, normalized plate surface retains strong Goss texture, it penetrates into the 1/4 thickness of the plate and forming strong {...

借助实验室设备研究了B元素对高牌号无取向硅钢热轧板组织和磁性能的影响。结果表明,与无硼钢相比,含硼钢的热轧板晶粒尺寸略小,析出物的类型和尺寸没有区别,主要是AlN和(AlN+MnS)复合析出物,少量的MnS析出物,尺寸集中在1.0~2.5μm范围内。未发现BN析出物。在力学性能方面,B对钢的软化作用不明显。在磁性能方面,含硼钢的铁损为3.215W/kg,磁感为1.710T,综合磁性能比无硼钢差。 Influences of boron on microstructure and properties of hot rolled band in high-grade non-oriented silicon steel are researched in this paper by experimental equipments.Compared with boron-free steel,the result shows that boron-bearing steel has smaller grain size,but the type and size of precipitations have no differences.The main precipitates are AlN,(MnS + AlN) composite precipitate and few MnS,the range of which are between 1.0 μm and 2.5 μm.BN precipitation is not found.With reward to mecha...
