Abstract

Abstract Steel production is considered as one of the major backbones of many economies. Though blast furnace is the primary route of steel production, the industries are willing to alternatives technologies such as the high temperature-controlled conversion of hematite to magnetite. The geological and mineralogical characteristics of the low-grade iron ores possess difficulties in their conventional enrichment. The literature concludes the advantages of high-temperature conversion in terms of easiness in downstream operations caused by decreased hardness and increased magnetic susceptibility of magnetite. The modelling work has been primarily focused on the direct reduction of iron ore to metallic iron. The present compilation discusses the scientific and engineering developments on the reduction-roasting of iron-ore followed by the CFD–DEM modelling and simulation work performed to reduce iron ore to magnetite. It provides a comprehensive review of the experimental and industrial progress done in the area.
赤铁矿流化床反应器化学还原制备磁铁矿模型研究进展
钢铁生产被认为是许多经济体的主要支柱之一。虽然高炉是钢铁生产的主要途径,但工业界愿意采用替代技术,如将赤铁矿转化为磁铁矿的高温控制技术。低品位铁矿的地质矿物学特征给其常规富集带来了困难。文献总结了高温转化的优点,即由于磁铁矿硬度降低和磁化率增加而易于下游操作。模拟工作主要集中在铁矿石直接还原为金属铁的过程上。本汇编讨论了铁矿石还原焙烧的科学和工程发展,随后进行了CFD-DEM建模和模拟工作,以将铁矿石还原为磁铁矿。它提供了在该地区所做的实验和工业进展的全面审查。
