1 绪言关于自熔性烧结矿的低温还原粉化现象的研究,过去有很多,但因其复杂,对本质方面的研究还有很多问题没有完成。文献报道了作者们基于过去的研究而进行矿物学的分类,搞清了赤铁矿的结晶形态的不同是RDI(低温还原粉化率)不同的主要原因,特别是在人造矿物中含有而天然矿物中不存 INTRODUCTION There have been many studies on cryogenic reduction and pulverization of self-fluxing sinter. However, due to its complexity, there are still many problems in the study of its nature. It has been reported in the literature that mineralogy was classified by the authors based on previous studies and clarified that the difference in crystallographic form of hematite is the main reason for the difference in RDI (low-temperature reduction pulverization ratio), especially in man-made minerals Not in the minerals
