Advantages of Magnesia Alumina Spinel Brick 1. Excellent stickability to kiln coating performance; 2. Low thermal conductivity and small thermal expansion coefficient; 3. It has excellent structural flexibility, and has strong erosion resistance and penetration resistance to K2SO4, Na2SO4, NaCl and KCl alkali salts decomposed by cement materials. 4. High load softening temperature and excellent thermal shock resistance, suitable for key parts of SP and NSP kilns with high kiln temperature, fast speed, strong alkali erosion ability and heavy mechanical load, which can effectively extend the life of the furnace lining and maintain a low temperature of the kiln barrel. 5. Good anti-peeling performance:Magnesium aluminum spinel brick is better than the direct combination magnesia-chrome brick at anti-peeling performance. The life of the cooling zone and the transition zone of the kiln can be directly combined with magnesia-chrome brick.
