韶钢7号高炉护炉操作实践

Operation practice of No.7 blast furnace protection at SISG

针对高炉本体长高,炉身冷却壁大量烧坏,炉缸区域炉墙侵蚀,炉缸侧壁温度偏高现象,总结出炉龄后期的护炉操作技术,为今后高炉长寿管理提供了技术依据。

In view of the phenomenon that the blast furnace body is high,the cooling wall of the blast furnace body is burnt out,the furnace wall in the hearth area is eroded,and the temperature of the side wall of the blast furnace is high,the operation technology of protecting the blast furnace is summarized in the late stage of the blast furnace life,which provides the technical basis for the management of blast furnace longevity in the future.
