钙处理对冷轧无取向硅钢磁性的影响

Behavior of microinclusions in cold-rolled non-oriented silicon steel

摘要: 通过金相显微镜、图像分析仪、扫描电镜和透射电镜等手段,研究了未用和采用钙处理无取向硅钢片中微细夹杂物的数量、尺寸分布以及夹杂物的类型.发现对无取向硅钢片铁损影响较大的是0.1~0.4μm的微细夹杂物,夹杂物类型对铁损影响较小.

Abstract: The amount, size distribution and style of microinclusions in non-oriented silicon steel sheets with or without calcium treatment were studied by metalloscope, image analytical meter, scan electron microscope and transmission electron microscope. The results show that microinclusions in the range of 0.1 to 0.4 μm influence the core loss of silicon steel sheets greatly but the style ofmicroinclusions has less influence.
