碱金属对高炉的危害,是随高炉精料的发展和冶炼强度提高而出现的一个新问题,特别是高炉炉身寿命因碱金属的严重侵蚀而日趋缩短,一代高炉往往要经过2—3次中修.围绕延长炉身寿命,我们对碱金属的浸蚀机理及防治问题进行了一些研究和探讨。通过对高炉破损调查,基本查清了碱金属对 The harm of alkali metals to the blast furnace is a new problem that arises with the development of blast furnace concentrate and the improvement of the smelting strength. In particular, the life of a blast furnace shaft is shortened due to the severe attack of alkali metals. A generation of blast furnaces often undergo 2-3 times In the repair around the extension of the life of the shaft, we attack the mechanism of alkali metal and prevention and treatment of some of the research and discussion. Through the blast furnace damage investigation, basically found out the alkali metal pair
