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

摘要: 通過金相顯微鏡、圖像分析儀、掃描電鏡和透射電鏡等手段,研究了未用和采用鈣處理無取向硅鋼片中微細夾雜物的數量、尺寸分布以及夾雜物的類型.發現對無取向硅鋼片鐵損影響較大的是0.1~0.4μm的微細夾雜物,夾雜物類型對鐵損影響較小.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.
