高炉长寿是提高高炉自身经济效益以及提高联合企业的炼钢、轧钢设备使用效率,从而使联合企业获得最大综合效益的有效措施。我国高炉寿命普遍低于国外先进高炉水平,中小高炉寿命更低。国外先进高炉不中修寿命达10年以上,而我国中小高炉不中修寿命只有2～4年,影响高炉一代寿命的因素很多,有设计的、施工的和生产的因素。从设计角度来讲,高炉寿命的长短,与高炉内衬的结构及耐火材料的选择,冷却设备的结构及材质,冷却介质及冷却系统设计有关。近几年来,我们先后为河北、河南、山东、
The longevity of the blast furnace is an effective measure to improve the economic benefits of the blast furnace and to improve the efficiency of using the steel making and rolling equipment of the joint ventures so that the joint ventures can get the most comprehensive benefits. China’s blast furnace life is generally lower than the level of advanced foreign blast furnace, blast furnace life is lower. Foreign advanced blast furnace does not repair the life of more than 10 years, and our small and medium blast furnace does not repair life is only 2 to 4 years, many factors affect the life of blast furnace generation, there are design, construction and production factors. From the design point of view, the length of the blast furnace life, and the blast furnace lining structure and refractory choice, the structure and material of cooling equipment, cooling media and cooling system design. In recent years, we have for Hebei, Henan, Shandong,
