The development of the technology of silica - mullite brick 2

In the transition zone and decomposition zone of cement gyrator, the traditional high alumina brick with anti peeling and acid salt combination is replaced by silica fume brick, and good application effect is achieved based on the improvement of the service performance of silica fume brick, After adding kyanite, sillimanite and andalusite, the high-temperature strength, creep resistance and thermal shock resistance of the products have been significantly improved through the use of its high-temperature expansibility. After adding andalusite to the silica fume brick, the silica fume brick has better seismic stability and wear resistance, and has achieved good application effect in cement density.
