摘要
昆钢2000m3高炉使用全国产耐火材料、开炉3年后炉体便发生持续上涨的情况，经认真开展炉体上涨的综合治理工作，并采用铁口维护、炉衬喷补和含钛料护炉等长寿技术后，一代炉役无中修，并长达十二年以上，单位炉容产铁9527t／m3，实现了高炉长寿生产。
The national refractory material was used for Kungang 2 000 m3 blast furnace, furnace continued to rise after the third year, comprehensive management work for furnace rising was implemented, and technologies for prolonging campaign life of BF were adopted, such as maintaining taphole, gunning technology, protecting furnace of titanium material. Campaign Life was over 12 years without furnace middle repair, production of pig-iron per unit blast furnaces＇ volume reached 9 527 t/m3, blast furnace longevity production was realized
