Characteristics and application of phosphate brick
The load softening temperature of phosphate high aluminum brick is not about 1350 degrees, but the wear resistance coefficient is high. The load softening temperature of the phosphate high aluminum brick rises from 1520℃ to 1570℃, and after the phosphate impregnation, the porosity decreases obviously, the bulk density increases, and the bending strength also increases a lot.
The upgraded phosphate composite brick combined with high-aluminum brick reduces the skin temperature of rotary kiln after adding light components. The dense phosphate composite brick with more than 2.8 is used for burning white ash rotary kiln, and the effect is good. In addition, the application range of phosphate high-aluminum bricks is not too large, and it is mostly used in the transition belt, cooling belt, castor cooling machine, kiln head cover and so on.
