炉内操作技术:合理煤气利用降燃产通过对2 500 m3高炉开炉以来大量数据进行分析,结合高炉自身特性及现有高炉原燃料情况;逐步确立2 500 m3高炉“上部适当疏导边缘下部较高鼓风动能”的操作指导思想,使高炉煤气分布更加合理,提高了CO利用率,从而达到降低燃料比的目标·首先,结合
In-furnace operation technology: Reasonable gas utilization Combustion production analysis A large amount of data was analyzed by blast furnace 2 500 m3 blast furnace, combined with the characteristics of the blast furnace and existing blast furnace fuel; gradually established 2 500 m3 blast furnace “ High blast kinetic energy ”operational guidelines, the blast furnace gas distribution more reasonable and improve the utilization of CO, so as to achieve the goal of reducing fuel ratio · First of all, combined with
