在不断摸索实践基础上开发出了以“大角度、大角差、大矿批、中心加焦”为核心的新型无钟炉顶布料技术。通过实施该技术,可提高炉况的稳定性,增强高炉抵抗原燃料波动的能力,稳定高炉气流分布,活跃炉缸工作状态,使高炉的各项经济技术指标明显改善。 On the basis of continuous exploration and practice, a new bell-less top fabric technology has been developed with “large angle, large angle difference, large ore batch and center plus coke” as its core. By implementing this technology, the stability of the furnace condition can be improved, the ability of the blast furnace to resist the fluctuations of the original fuel, the steady flow distribution of the blast furnace and the active hearth working condition can be improved, so that various economic and technical indicators of the blast furnace can be obviously improved.
