国内外高炉多年的操作实践证明,要达到良好的技术经济指标,在高炉操作上必须实行上下部调节相结合.近年来,许多高炉采取分装大料批,对于改变多年来沿用的发展边缘气流和“馒头形”煤气曲线,改善煤气利用起了一定作用.要进一步降低燃料比,除了加强上部调节,还要注意下部调节,特别是要重视风口前理论燃烧温度.
Blast furnace operation at home and abroad for many years has proved that in order to achieve good technical and economic indicators, blast furnace operation must be implemented on the lower part of the combination of adjustment. In recent years, many blast furnace to take sub-large batch of materials to change the development of edge flow And “steamed bread” gas curve, to improve gas utilization played a role.To further reduce the fuel ratio, in addition to strengthening the upper regulation, but also pay attention to the lower regulation, in particular, should pay attention to the tuyere theoretical combustion temperature.
