随着高炉的容积增大,操作不断强化以及其它一些因素,延长炉身寿命越来越突出地成为高炉工作者的主攻对象之一。在解决高炉炉身结构的课题上,现在国外主要精力放在对价格昂贵的高级耐火内衬(如刚玉砖、氮化硅结合的或自结合的碳化硅砖……)及支承这些内衬的结构研究工作 As the blast furnace volume increases, operations continue to strengthen, and other factors, extending the life of the blast furnace becomes more and more prominent as one of the main targets of blast furnace workers. To solve the problem of blast furnace shaft structure, foreign countries now mainly focus on the high cost refractory lining (such as corundum brick, silicon nitride bonded or self-bonded silicon carbide brick ...) and the support of these linings Structural research work
