影响氧化铝产量的一个关键因素,就是窑龄低,平均窑龄达不到一周时间,使大窑生产经常处于抢修内衬的被动局面,它既严重的影响着氧化铝产量,又造成大量的人工、物料的浪费。通过现场抢修任务的观察,笔者认为我们的窑内衬,用耐火砖砌筑法,不如改用耐火骨料钢筋混凝土浇注的方法,把窑体内衬象浇注大水泥管那样,浇注成一个附在窑体内部的整体筒型耐火骨料钢筋混凝土窑内衬。应用这一技术浇注窑内衬,就可克服因砌筑技术和耐火砖自重在外力冲击
A key factor affecting the output of alumina is the low kiln age and the average kiln age of less than one week, which makes the production of large kilns often in the passive situation of repairing lined steel. It not only seriously affects the production of alumina, but also causes a large amount of Artificial, material waste. Through the on-site repair mission observation, I believe that our kiln lining, with refractory brick masonry method, it is better to use refractory aggregate reinforced concrete pouring method, the kiln body lining like pouring large cement pipe, pouring into a In the kiln interior monolithic refractory aggregate reinforced concrete kiln lining. Application of this technology pouring kiln lining, you can overcome the masonry technology and refractory weight in the external impact
