    摘要
  • 摘要: 針對衡鋼"EAF-LF-VD-HCC"工藝生產的水平連鑄管坯鋼,通過運用金相顯微鏡、掃描電鏡、EDAX 能譜儀、電子探針、電解、示蹤劑跟蹤法等各種分析手段及方法,對 LF 處理前后,VD 處理后,中間包鋼水及連鑄坯,重點是吊包鋼水,中間包鋼水和連鑄坯所取試樣中所含的顯微夾雜物及大型夾雜物進行了研究.結果表明,管坯鋼顯微夾雜相對個數為 16.1 mm-2,大型夾雜物數量為 214.6 mg·kg-1.

     

    Abstract: In view of the steel tube produced by "EAF-LF-VD-HCC" horizontal continuous casting process, micro and large inclusions in the steel before and after LF, after VD, in tundish and casting blank were studied by using optical microscope, scanning electron microscope, EDAX energy dispersive spectroscopy, electron microprobe, electrolysis, tracer tracking and other analytical tools and methods. The results show that the relative numbers of tube steel micro-inclusions and macro-inclusions are 16.1 mm-2, and 214.6 mg·kg-1, respectively.
