摘　　要：莱钢炼铁厂分析1 000 m^3高炉特点,推行经济冶炼技术。制定了满足高炉提升产能的烧结矿、球团矿、生矿、焦炭等原燃料质量标准,加强原料管理,建立日核算制度、高炉成本控制模型。通过提高风温,增加喷煤量,确定风口布局,提高炉顶压力等操作,高炉燃料比由2015年的544 kg/t降低到2016年的533 kg/t,高炉利用系数由3.0 t/(m^3·d)提高至3.25 t/(m^3·d)。The characteristics of the 1 000 m3 blast furnace was analyzed and the economic smelting technology was carried out in Laiwu Steelmaking Plant. To improve the capacity of blast furnace, the quality standard of sinter, pellet, ore, coke and other raw fuel were made.The management for the raw materials was enhanced. The daily accounting system and the blast furnace cost control model were estab/ished. By increasing the air temperature and the amount of pulverized coal injection, determining the layout of the air outlet and raising the operation of top pressure, the blast furnace fuel ratio was decreased from 544 kg/t in 2015 to 533 kg/t in 2016. The utilization coefficient of blast furnace was increased from 3.0 t/（m3·d） to 3.25 t/（m3·d）.
