本文通过重钢三号高炉近六年的生产实践,说明自焙炭砖较高炉粘土砖和高炉高铝砖具有耐高温、抗渣铁侵蚀能力强和抗碱金属侵蚀能力强等优点,说明自焙炭砖是中、小型高炉用于风口以下较理想的炉衬材料。文章分析了自焙炭砖在使用过程中所出现的问题及其原因,提出了解决的途径和意见。
In this paper, through the production practice of the No.3 blast furnace for nearly six years, it shows that the self-baking carbon bricks have the advantages of high temperature resistance, strong resistance to slag erosion and strong resistance to alkali corrosion, Baked carbon brick is medium and small blast furnace for the tuyere below the ideal lining material. The article analyzes the problems and their causes in the process of using self-baking carbon bricks, and puts forward the solutions and suggestions.
