摘要
阐述了国内熔融还原炼铁工艺的现状,介绍了几种主流熔融还原炼铁工艺,通过对比这几种熔融还原炼铁工艺的能耗,分析了目前主流的熔融还原炼铁所存在的优势与不足,并对新提出的回转窑-氧煤燃烧熔分炼铁工艺进行了阐述。通过将这几种工艺与回转窑-氧煤熔分工艺对比,了解新工艺回转窑-氧煤熔分的优势所在,提出非高炉炼铁未来的发展方向和目前非高炉炼铁所面临的关键科学与技术问题。
The status quo of domestic smelting reduction ironmaking process is expounded.Several mainstream smelting reduction ironmaking processes are introduced.By comparing the energy consumption of these smelting reduction ironmaking processes,the advantages of current mainstream smelting reduction ironmaking are analyzed.Insufficient,and the new proposed rotary kiln-oxygen combustion melting ironmaking process was elaborated.By comparing these processes with the rotary kiln-oxygen coal melting process,to understand the advantages of the new process rotary kiln-oxygen coal melting point,the future development direction of non-blast furnace ironmaking and the key to the current non-blast furnace ironmaking are proposed.Scientific and technical issues.
