The oxygen blast furnace (OBF) process has been extensively studied theoretically because of the potentials of promising energy conservation and CO₂ emission reduction. Herein, investigations of the OBF process are reviewed and some suggestions for its future development are presented. The main findings can be condensed into the following: static and dynamic models of the OBF should be revised to considering the newest theoretical findings in the thermodynamics and kinetics involved as well as the particular limitations of the technology. Models focusing on energy demand and emissions should be further developed and applied to enhance the design for increased efficiency and sustainability of the complicated OBF system. It will be challenging to operate the full OBF process with top gas recycling (TGR). The development of mathematical models focusing on the practical operation is therefore warranted and would provide useful tools for tackling control problems and difficulties that will arise in forthcoming industrial trials. Considering these potential challenges, a medium oxygen‐enriched blast furnace with TGR as a forerunner is suggested because its operation conditions show greater resemblance with those of the traditional blast furnace. This furthermore provides a path of transition to the use of the full OBF in industrial scale.

氧气高炉工艺研究综述

由于有希望实现节能和CO ₂的潜力，因此对氧气高炉（OBF）工艺进行了理论上的广泛研究。减排。在此，对OBF过程的研究进行了回顾，并提出了对其未来发展的一些建议。主要发现可以归纳为以下内容：应修改OBF的静态和动态模型，以考虑所涉及的热力学和动力学的最新理论发现以及该技术的特殊局限性。应进一步开发和应用以能源需求和排放为重点的模型，以增强设计，以提高复杂的OBF系统的效率和可持续性。使用顶部气体再循环（TGR）来运行整个OBF工艺将是一个挑战。因此，有必要开发专注于实际操作的数学模型，并将为解决控制问题和即将进行的工业试验中出现的困难提供有用的工具。考虑到这些潜在挑战，建议使用以TGR为先驱的中富氧高炉，因为其运行条件与传统高炉的运行条件更为相似。此外，这提供了向工业规模使用完整OBF的过渡途径。
