Abstract：The strengthening process of hematite pellets made from iron ore concentrateof Kunming Iron and Steel Company has been examined by SEM, X-ray diffrac-tion, etc. to ascertain the strengthening mechanism when they were fired undertemperatures between 1000 to 1350℃. The hematite crystallites began to growinto trigonal platelets and to cross-connect each other at temperature up to 1000℃.Until 1200℃, the cross-connexion was further strengthened into solid framework.Thus, it seems to be easily clarified why a rather firm strength of pellets isdisplayed earlier under lower firing temperatures. Perhaps, neither molten slagformed over the surface of hematite crystals with vein and impurities nor a fewof magnetite crystallized out of melt will play a dominante role in the strengtheningprocess of this hematite pellets. 收稿日期: 1980-01-18      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 刘富有 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1980/V16/I1/18 No related articles found!
