摘　　要：球团与烧结生产相比更节能、更环保,采用高比例球团炉料结构是高炉实现低碳绿色炼铁的有效途径。高炉进行高比例球团冶炼,实现熔剂性球团的工业化生产是关键,带式焙烧机生产熔剂性球团具有很大的工艺优势。唐钢新区3座3000 m^(3)级高炉设计采用50%~70%球团的炉料结构,并配套建设了2台624 m^(2)大型带式焙烧机。为了打破国外对大型带式焙烧机的长期技术垄断,唐钢对带式焙烧机工艺技术及装备进行了全面研发。通过精粉预处理、配矿及焙烧工艺技术的开发,掌握了中高硅熔剂性球团生产技术;通过装备国产化的设计制造与应用研究,实现了大型带式焙烧机核心装备的国产化,打破了国外的长期垄断;通过智能化技术开发与应用,实现了球团产线的高效协同,显著提高了带式焙烧机的生产效率;通过低能耗低排放技术的开发与应用,大大降低了球团工序能耗和污染物排放量,实现了低碳绿色生产。大型带式焙烧机的开发应用首次实现了全自主研发设计及装备的国产化,为带式焙烧机的推广应用打开了新局面。唐钢已成熟掌握熔剂性球团生产技术和高炉高比例球团冶炼技术,其对高炉炉料结构的探索和实践为中国高比例球团炉料结构的推广应用起到很好的引领示范作用。Compared with sintering production,pellet production is more energy-efficient and environmentally friendly.The burden structure with high proportion of pellet is an effective way for blast furnace to achieve low carbon and green ironmaking.It is the key to realize the industrial production of fluxes pellets in blast furnace for high proportion pellet smelting.The belt roasting machine to produce fluxes pellets has great technological advantages.The three 3000 m^(3) blast furnaces in Tangsteel New District designedly adopted 50%-70%pellet structure,and two 624 m^(2) large-scale belt roasting machines were set up.In order to break the long-term technological monopoly for large-scale belt roasting machine abroad,the comprehensive research and development on the process technology and equipment of belt roasting machine was carried out in Tangsteel.Through the development of fine powder pretreatment,ore blending and roasting technology,the production technology of medium and high silicon flux pellets was mastered.With the design,manufacture and application research for the equipment localization,the localization of the core equipment of the large-scale belt roasting machine was realized to break the long-term monopoly of foreign countries.Through the development and application of intelligent technology,the efficient cooperation of pellet production line was obtained,and the production efficiency of belt roasting machine was significantly improved.Additionally,with the development and application of low energy consumption and low emission technology,the energy consumption and pollutant emission of the pelleting process were significantly reduced,the low-carbon and green production was realized.Apparently,the development and application of large-scale belt roasting machine in Tangsteel has achieved the full independent research,development and design of large-scale belt roasting machine and the localization of equipment for the first time,which has opened up a new situation for the promotion and application of belt roa
