摘　　要：高炉煤比是体现高炉操作技术水平的重要指标,也是降低高炉焦炭消耗和生产成本的主要途径之一。结合新钢1000 m^(3)高炉的实际情况,对影响煤比的原因进行分析,并从原燃料管理、用料结构、高风温、大富氧、高顶压、设备管理等方面进行综合调节,使煤比由145 kg/t逐步提高到162 kg/t,焦比从400 kg/t下降至385 kg/t,有效地降低了铁水成本。The coal ratio of blast furnace is an important indicator reflecting the level of blast furnace operation technology,and it is also one of the main ways to reduce coke consumption and production costs of blast furnace.This article analyzes the reasons that affect the coal ratio based on the actual situation of the 1000 m^(3) blast furnace at Xinyu Steel,and comprehensively adjusts it from the aspects of raw material management,material structure,high air temperature,high oxygen enrichment,high top pressure,equipment management,etc.,gradually increasing the coal ratio from 145 kg/t to 162 kg/t and reducing the coke ratio from 400 kg/t to 385 kg/t,effectively reducing the cost of molten iron.
