摘　　要：针对焦炭质量劣化的状况 ,高炉操作以活跃炉缸为主 ,从上下部调剂入手 ,采取疏导煤气、控制合理的实际风速和鼓风动能、缓解焦炭在高温区的粉化等措施 ,有效地改善了高炉的顺行状况 ,并逐步恢复高炉指标。The production indexes were deteriorated due to bad quality coke,such methods as increasing permeability of gas, controlling rational actual blast velocity and kinetic energy of blast, and decreasing pulverization of coke during high-temperature zone of blast furnace were adopted, which have improved both the situation of blast furnace and production indexes.
