摘　　要：为深入贯彻“双碳”战略,唐钢公司在大型高炉应用了50%以上高比例球团的设计。3座高炉自2020年9月相继投产以来,技术人员不断摸索高比例球团的冶炼特点,充分挖掘现有技术装备和工艺技术条件下高炉的降碳能力,通过对布料制度、送风制度、热制度、造渣制度、冷却制度等高炉基本操作制度进行优化,形成了一套适应自身条件的低碳高效操作技术及相应的管理制度,实现了高炉的长周期稳定顺行。2024年高炉主要技术经济指标稳定(球团矿+块矿配比50%、煤比170 kg/t、使用风温1230℃,CO_(2)排放降低96.41 kg/t),实现了阶段性的突破。In order to thoroughly implement the“double carbon”strategy,Tangsteel company has applied the design of more than 50%high proportion pellets in large blast furnaces.Since three blast furnaces have been put into operation successively in September 2020,they have continuously explored the smelting characteristics of high-proportion pellets,fully tapped the carbon reduction capacity under the existing technical equipment and process technology conditions,and optimized the basic operation duty such as the charging pattern,air supply system,thermal balance,slag-making and the cooling rigime.It has formed a set of low-carbon and efficient operation technology as well as corresponding management system that adapt to its own conditions to achieve long-term stable and smooth operation of the blast furnace.In 2024,the main technical and economic indicators of the blast furnace are stable(the proportion of pellet ore and lump ore is50%,coal ratio is 170 kg/t,air temperature is 1230℃and the decrease of CO_(2)emission is 96.41 kg/t),achieving a phased breakthrough.
