摘要

摘要: 镁质球团矿因其冶金性能优良,已经成为球团矿发展的重要方向,但镁质球团矿也存在着强度差且焙烧工艺参数要求高的问题,研究并寻求改善镁质球团矿的焙烧固结机理具有重要的现实意义。文章综述了近年来镁质球团矿焙烧固结机理及强化的研究进展,系统介绍了Mg的形式、配比、焙烧工艺参数、矿物组成、微观结构等因素对镁质酸性球团矿、镁质熔剂型球团矿成矿机理及冶金性能的影响,为镁质球团矿进一步发展提供基础数据及方向参考。

Abstract: Magnesia pellets have become a major trend in the development of the pellets in the future due to its good metallurgical performance.However,problems such as low strength and high demands for roasting process parameters are existing for magnesia pellets.Therefore,it is of important practical significance to study roasting and induration mechanism and then improve process of magnesia pellets.The recent development of roasting and induration mechanism of magnesia pellets and effects of Mg’s source,ratio,process parameters,mineral composition and microstructure on the metallogenic mechanism and metallurgical properties of magnesium acid pellets and magnesian flux pellets were systematically reviewed in this paper,for the purpose of providing basic data and the reference for further promoting magnesia pellet.
