Climate change poses a shared global challenge. Given its substantial contribution to CO emissions, the steel industry must shoulder a significant responsibility for the carbon neutrality goal. Achieving carbon neutrality in the iron and steel industry is a complex and gradual endeavor, requiring sustained efforts rather than offering a swift resolution in practical terms. Despite the ambitious development of numerous non-blast furnace processes, the traditional blast furnace (TBF) is poised to persist as the dominant ironmaking process in the upcoming decades. Conversely, the oxygen blast furnace (OBF) process, distinguished by its exceptional emission reduction potential and low retrofit costs, emerges as one of the most promising ironmaking technologies for the future. Therefore, this review comprehensively explores the origin and evolution of the OBF process, elucidating technological advancements across various historical periods. Furthermore, the review puts forth a comprehensive analysis of the feasibility of employing the OBF process for smelting vanadium-titanium magnetite (VTM), considering the benefits of the OBF and the challenges it encounters. Looking ahead, the advancement of the OBF should concentrate on pivotal domains like enhancing furnace condition control technology, exploring and innovating coke substitutes, and developing new materials with high-temperature and oxidation resistance. Concurrently, the Carbon Capture, Utilization, and Storage (CCUS) technologies are vigorously developed to further enhance the carbon reduction potential of OBF. This review aims to ignite readers’ research curiosity regarding the OBF process and its application in smelting VTM. It also endeavors to propel the industrialization process and foster the sustainable development of the OBF.

氧气高炉技术进展及其在钒钛磁铁矿冶炼中的应用综述


气候变化构成了共同的全球挑战。鉴于其对二氧化碳排放的巨大贡献，钢铁行业必须对碳中和目标承担重大责任。钢铁行业实现碳中和是一项复杂而渐进的工作，需要持续的努力，而不是在实际中迅速解决。尽管许多非高炉工艺的发展雄心勃勃，但传统高炉（TBF）在未来几十年仍将继续作为主要炼铁工艺。相反，氧气高炉（OBF）工艺以其卓越的减排潜力和较低的改造成本而著称，成为未来最有前途的炼铁技术之一。因此，本文全面探讨了OBF工艺的起源和演变，阐明了各个历史时期的技术进步。此外，考虑到OBF工艺的优点及其遇到的挑战，该综述对采用OBF工艺冶炼钒钛磁铁矿（VTM）的可行性进行了全面分析。展望未来，OBF的发展应集中在强化炉况控制技术、探索创新焦炭替代品、开发高温抗氧化新材料等关键领域。同时，大力发展碳捕集、利用和封存（CCUS）技术，进一步增强OBF的减碳潜力。本综述旨在激发读者对OBF工艺及其在VTM冶炼中的应用的研究好奇心。 努力推动OBF工业化进程，促进OBF可持续发展。
