摘　　要：包钢2200m^(3)高炉在环保限产、烧结矿紧张的情况下,使用大比例球团矿正在成为炼铁炉料结构发展的新趋势。通过对布料矩阵带宽、中心焦量和料段排料顺序、风口直径和长度、炉缸热量储备、炉渣碱度的调整和控制,操作上积极应对球团比例增加后炉况出现的变化,高炉炉况保持了稳定顺行的局面,包钢在2200m^(3)级高炉上成功实现了大比例球团矿的应用,球团矿比例最高达到50%。Under the circumstances of environmental protection,production limitation and tension supply of agglomerate,it is becoming a new trend in the development of furnace burden structure for iron making to use large proportion of pellet in 2200 m~3 blast furnace of Baotou Steel.The blast furnace condition maintains stable and trouble-free,application of large proportion of pellets in 2200 m~3 blast furnace of Baotou Steel is successfully realized and the proportion of pellet is up to 50%through adjusting and controlling the bandwidth for matrix of burden distribution,amount of central coke,sequence of material discharge at output section,diameter and length of the tuyere,heat reserve of hearth,basicity of slag as well as actively responding to the changes of furnace condition for operations after the proportion of pellet increases.
