4000 m3以上大型高炉是高炉炼铁先进技术的集中体现,相对于容积小的高炉,大型高炉单位炉容投资少、能耗低、环境负荷低、劳动生产率高.2000年以来,随着钢铁需求的迅猛增加,一批4000 m3以上大型高炉在中国相继投入运行,在炼铁工作者的不懈努力下,大型高炉的操作管理取得了突出的成绩和效果.通过分析中国4000 m3以上大型高炉的生产现状,对存在的问题提出了改进建议,并对炼铁今后的发展进行展望,希望对中国高炉炼铁的发展有一定促进作用.
Large blast furnaces with volume larger than 4000 m3 is the concentration represents of new techniques in ironmaking blast furnace. Compared to the blast furnace with small volume,blast furnace with larger volume has lower economic investment,smaller energy consumption and environmental load,higher labor productivity. A large number of 4000 m3 blast furnaces were built when the steel demands increased dramatically after the year of 2000. In the efforts of ironmaking operators,the operation indexes of large blast furnace have reached advanced levels. In this paper,the op-eration situation of large blast furnace was analyzed,while some suggestions for existing problems were proposed. In ad-dition,the tendencies of ironmaking in future were prospected,hoping it could improve the development of ironmaking in China.
