采用X-射线衍射分析技术测定了取向硅钢热轧板在不同压下率下不同厚度处的织构。结果表明,在压下率低于80%的情况下,几乎所有试样的不同厚度处的织构均为旋转立方织构类型{100}<011>,但不同压下率、不同厚度处的织构强度存在很大差异;在压下率大于80%的情况下,不同试样的不同厚度处的织构类型发生了变化,其织构类型为旋转立方织构或高斯织构{011}<100>,且当织构类型为旋转立方织构时,织构强度存在很大差异,而当织构类型为高斯织构时,织构强度差异相对较小。 The texture of the grain oriented silicon steel hot rolled plate at different compressibility has been measured.The experimental results have shown that the texture of all samples at different thickness is {100}<011> when the compressibility is below 80%,and its intensity at different compressibility and thickness is difference.The texture of all samples at different thickness is variable when the compressibility is above 80%,it is {100}<011> or {011}<100>,and the intensity of ...

采用双辊薄带连铸工艺制备了厚度为2.4mm的3.98%Si-0.71%Al无取向硅钢带,经常化、冷轧、不同温度退火后,对其显微组织、析出物、织构和磁性能进行了检测分析。结果表明:随着退火温度的提高,退火板晶粒尺寸增大,组织均匀性提高;退火板析出物主要是AlN和MnS与AlN复合析出物,尺寸较粗大,达0.5~2.5μm;退火板织构沿厚度方向变化明显,表层和1/2层存在较强的{100}织构,1/2层还存在较强的{111}织构,1/4层主要是{112}织构;随退火温度的升高相应的铁损和磁感应强度均降低。 Using twin roll thin strip continuous casting technique,the 3.98%Si-0.71%Al no-oriented silicon steel strip in thickness of 2.4mm was produced.The microstructure,precipitates,texture,and magnetic properties of the sheet after normalizing,cold rolling and annealing at different temperatures were studied.The results show that with annealing temperature increase,the grain size and uniformity of annealed sheet increased.The main precipitates in coarse size of 0.5-2.5μm in annealed sheet were AlN and...
