Advantages of domestic magnesia spinel bricks applied in cement kiln
Magnesia spinel brick has the advantages of chromium-free environmental protection, good thermal shock stability,good kiln skin,good corrosion resistance,low thermal expansion and low thermal conductivity,and good structural flexibility.In practical application,the service life of the brick is more than 1 year,the kiln skin is burned quickly,the thickness of the kiln skin is even and stable,and the refractory brick has no large slump.The kiln has no refractory brick peeling phenomenon,and the temperature of the kiln cylinder is low,and the loss of heat energy is low.
