摘　　要：从冶炼强度、冷却强度、温度变化等几方面分析了莱钢 1#75 0 m3高炉炉壳变形、冷却壁损坏的原因。通过采取提高冷却强度、将冷却壁材质由耐热铸铁 RTCr-0 .5改为球墨铸铁 QT40 0 -18、改变冷却壁套管与炉壳间的安装方式、冷却壁之间填充碳化硅质的填料、控制炉壳开孔数量及质量、加强冶炼操作稳定炉况等措施 ,延长了高炉炉体的使用寿命。The causes of deformation of shell and defects of cooling walls of No 1 750m 3 blast furnace at Laigang are analyzed from the aspects of the intensities of melting and cooling and the temperature change etc The service life of blast furnace body can be extended by taken measures including improving cooling intensity, changing cooling wall materials from RTCr 0 5 to QT400 18, changing installation type between the shell and the cooling wall sleeve pipes, filling in the intervals of the cooling walls with SiC, controlling the quantity and quality of opening on the shell, strengthening the iron-making operation and stabilizing the furnace condition etc
