摘　　要：通过对HCl气体侵蚀高炉耐火材料的研究发现:HCl气体可以促使高铝砖中硅酸盐玻璃质和隐晶质铝硅酸盐转变成莫来石和方英石,导致气孔率提高;HCl气体与碳砖中非碳元素发生反应产生盐酸盐,导致碳砖质地变得疏松,气孔率增加,加速碳砖在高炉内的熔损反应.According to the study on blast furnace refractory erosion caused by HCl gas, it was found that HC1 gas can promote for the silicate glass phase and the recessive aluminum silicate to transform into mullite and cristobalite in the alumina brick, so that it can increase the porosity in the alumina brick. HCl gas reacts with non - carbon elements to form the chloride which causes the brick to be loose and porous in the carbon brick. Thus the brick loss is accelerated.
