关于大中型长寿高炉设计

On design of large and medium size long campaign blast furnace

提出了长寿高炉的基本设计思想。进行长寿高炉设计,必须对高炉合理内型、合理内衬结构和不同部位耐火材料的选择、冷却方式和冷却系统(包括冷却器的结构、材质与水质等)及其它有关方面综合考虑。武钢5号(3200m^3)高炉设计炉型比较合理,炉缸直径为12.2m,高径比为2.28,并采用了全立式冷却壁、软水密闭循环冷却系统等先进技术措施。

The basic concept of designing long campaign blast furnace was put forward.During designing long campaign blast furnace,the rational; furnace profile,rational furnace lining structure and selection of different refractories for various areas,cooling method and system (including cooler structure and material,cooling water and so on) and concerned aspects must be comprehensively considered.The No.5 (3200 m3) blast furnace at Wuhan Iron and Steel (Group) Co.was designed with rational profile,hearth diameter of 12-2m,height/hearth diameter ratio of 2.28 and was equipped with vertical cooling staves,closed loop soft water cooling system and other advanced technical measures for prolongation of furnace campaign.
