摘　　要：采用传统轧制工艺生产了高硅钢,对轧制后的Cr-6.5wt%Si试样进行了显微组织观察和力学性能测试。结果表明：Cr元素有利于变形带的生成和再结晶晶粒的形成,当Cr的添加量为2wt%时,高硅钢显微组织中的拉长状晶粒变得更加细小,并出现大量的变形带;随着Cr含量的增加,高硅钢的显微硬度降低,这有利于高硅钢轧制过程的进行。The high silicon steel was produced by traditional rolling process. Microstructure observation and mechanical properties testing of Cr-6.5wt%Si samples after rolling were carried out. The results show that the Cr element is conducive to the producing of deformation zone and the formation of recrystallized grains. When Cr is added to 2wt%, the elongated grains in the microstructure of the high silicon steel become smaller, and a large number of deformation bands are produced. With the increasing of Cr content, the micro-hardness of the high silicon steel decreases, which is conducive to the continuation of high silicon steel rolling process.
