Key words： vanadium-titanium-containing magnetite    smelting reduction    slag structure    reduction rate. 收稿日期: 1996-10-18      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 刘清才 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1996/V32/I10/1081 1刘清才、裴鹤年．重庆大学学报,1994;17(5):942王宏民、盛世雄．钢铁钒钛,1980;1(4):43张丙怀,刘清才．重庆大学学报,1988;11(13):134ZhangB,LiuQ,LiC,ZouD,SunJ．ActaMetallSin(EnglLett),1993;6B:3995刘清才、张丙怀,邹德余,涂敏．钢铁钒钛．1990;11(3):24Z [1] 杨学民;郭占成;于宪溥;艾菁;王大光.
