It has been found that the entrapment of slag during tapping could be thecause of the presence globular inclusions in the steel, but that most part of such inclu-sions especially large ones can be eliminated by taking appropriate measures duringmelting and teeming. 收稿日期: 1977-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1977/V13/I3/175 [1] Salter, W.
