包钢钢铁生产一直使用白云主,东矿矿石作原料,铁精矿经烧结机和带式球团焙烧机处理后用于高炉。由于主东矿中含有较多的稀土、铌等贵重元素,短期内还难以完全回收利用,此外还含有较高的氟、砱等对钢铁生产和环境保护有害的元素,因此准备开发稀土、铌、氟、砱等都较低的白云西矿供应钢铁生产,以保护主东矿的稀土、铌资源。为此在包钢钢研所开展了白云西矿造块工艺研究工作,探索白云西矿铁精矿进行烧结、球团的工艺特点,产质量指
Baotou Steel and Iron and Steel production has been using the main Baiyun, East ore ore as raw material, iron concentrate after sintering machine and belt pellet roasting machine for blast furnace. As the main ore contains more rare earth, niobium and other precious elements, the short term is difficult to completely recycle, in addition to higher fluorine, 砱 and other elements harmful to steel production and environmental protection, and therefore prepared to develop rare earth, niobium , Fluorine, 砱, etc. are lower Baiyun West Iron and Steel production supply to protect the main East Mine of rare earth, niobium resources. To this end in Baotou Steel Institute carried out Baiyun West mine block technology research work to explore the Baiyun West iron ore sinter, the pellet characteristics of the process, the production of quality refers to
