The most important characteristics of micro expansion high alumina brick are high structural strength at high temperature, small brick shrinkage, and tight overall structure without deformation after masonry.
During the use of traditional high alumina brick, due to the surrounding environment and high temperature, the brick body will shrink greatly, the brick joint will be large, and even fall off. Due to the change of temperature, it will lead to cracks and peeling off. In the traditional production process, the expansion agent with good performance at high temperature is added to enhance the matrix structure, so that the product has the characteristics of high load softening temperature, anti peeling performance, corrosion resistance and erosion resistance. After masonry, in the process of use, the integrity of masonry structure is effectively realized and the service life is improved
Micro expansion high alumina brick is now commonly used in ladle, mixer car, electric furnace top, cement rotary kiln and other kiln equipment. The application range is wider and wider, and the application effect is more than twice that of traditional high alumina brick.
