近年来,不断遇到有关发展熔融还原炼铁技术的问题。为此,本文就这个问题发表个人观点,供大家研究分析。一、世界发展熔融还原炼铁技术的背景1．几十年来,为减少对炼焦煤的依赖和环境保护的需要,有不少国家的研究机构和钢铁企业开展了熔融还原炼铁技术的研究,研发了多种熔融还原炼铁工艺。如,Dios工艺、Corex工艺、Hismelt工艺等。 In recent years, continue to encounter problems related to the development of smelting reduction ironmaking technology. To this end, this article published a personal opinion on this issue, for your research and analysis. First, the world development of smelting reduction ironmaking technology background 1. For decades, in order to reduce the dependence on coking coal and the need of environmental protection, many national research institutions and steel companies have carried out research on smelting reduction ironmaking technology and developed a variety of smelting reduction ironmaking processes. Such as, Dios technology, Corex technology, Hismelt technology.
