一、引言随着高炉容积的增大,操作上不断强化等,炉身寿命矛盾越来越突出地成为高炉工作者必须解决的课题之一。在解决高炉炉身结构的课题上,国外主要精力放在对价格昂贵的高级耐火内衬(诸如刚玉砖、氮化硅结合的或自结合的碳化硅砖等),以及支承这些内衬的结构研究工作上。国内大型高炉的动向似乎也在步其后尘,这难道是解决高炉炉身寿命的唯一出路吗?为此,作者撰文“试论无内衬的高炉炉身结构”。
I. INTRODUCTION As the volume of the blast furnace increases and operation continues to intensify, the contradiction of the lifespan of the shaft becomes more and more prominent as one of the issues that the blast furnace worker must solve. To solve the problem of blast furnace shaft structure, foreign countries mainly focus on the expensive refractory lining (such as corundum brick, silicon nitride bonded or self-bonded silicon carbide brick, etc.) and the structure supporting the inner lining Research work. It seems that the trend of the domestic large blast furnace is also followed. Is this the only way to solve the problem of the life of the blast furnace? For this reason, the author wrote “Trying on the structure of a non-lined blast furnace shaft”.
