对宝钢2号高炉(第二代)长寿维护生产实践进行了总结。针对炉体出现的问题,主要通过炉壳空冷及雾化洒水冷却、安装封罩并不断优化封罩、冷却板查漏及更换等措施的实施,有效控制炉体状况的恶化和发展,为高炉稳定顺行创造条件;针对炉缸存在的问题,主要采取炉缸压浆维护、加强炉役后期炉缸日常管理和调整下部送风制度等措施,使高炉炉缸侧壁温度受控,炉缸热负荷稳定。
The longevity maintenance and production practice of Baosteel No. 2 blast furnace (second generation) was summarized. For furnace problems, mainly through the furnace shell air-cooled and atomized water spray, the installation of enclosures and continue to optimize the enclosure, leak detection and replacement of cold plate and other measures to effectively control the deterioration and development of furnace conditions for the blast furnace Stable and forward to create conditions; Aiming at the problems existing in the hearth, the main furnace hearth grouting maintenance, to strengthen the late furnace hearth furnace daily management and adjustment of the lower air supply system and other measures to blast furnace hearth side wall temperature control, hearth Heat load is stable.
