3, the structure of the excellent flexibility, decomposition of cement material K2SO4, Na2SO4, NaCl, KCl alkali salt content of the erosion resistance and resistance to penetration ability.
4, high refractoriness under load, good thermal shock resistance, is suitable for the kiln temperature is high, fast speed, strong alkali corrosion and mechanical load of the key parts of the great SP and NSP kiln, can effectively extend the service life of furnace lining and maintaining low kiln shell temperature.
Application shows that: magnesia spinel brick is suitable for large under the calcining zone and transition zone of cement rotary kiln is alternative magnesite-chrome brick pollution caused by pollution of Cr6, + new products and the best choice.
