Phosphate Bonded Abrasive High Alumina Refractory Brick for Cement Industry
The Description:
Phosphate-high aluminum brick is one of the commonly used brick types of new dry process cement kiln, referred to as phosphate high aluminum brick or phosphate brick, based on high bauxite clinker as the main raw material, with phosphoric acid or aluminum phosphate as the adhesive, high pressure molding, in 400? High alumina refractory products, made by heat treatment at 600ºC. Phosphate-type high alumina brick has good thermal stability, when the temperature of cement kiln lining changes sharply, the high alumina phosphorus brick will not burst, do not flake off, and the kiln skin will not collapse. And easy to hang kiln skin, wear resistance, long service life.

Application:.
Widely used in cement kilns, it can be used for pre-tropical zone, decomposition zone, transition zone, cooling zone lining. It can also be fired into strips with a cement kiln with a diameter of less than 3 meters.
classify
Building materials Industry standard JC350-1993 "phosphate bonded high alumina cement kiln bricks" is divided into two types according to the binder. The concentration of phosphate high aluminum brick bond is 42.5%. 50% liquid phosphate. The code is P, and the lock seam brick code is PC. High aluminic acid type wear-resistant brick (referred to as wear-resistant brick) prepared by industrial phosphoric acid and aluminum hydroxide, prepared by industrial aluminum hydroxide, its molar ratio is Al2O3:P2O5=1:3.2, code PA
Advantage:
High aluminum-phosphorus composite brick has high thermal strength, good thermal impact performance, good wear resistance and easy to hang kiln. Some cement manufacturers use it to produce small rotary kiln firing belt, transition belt, in the commissioning process often appear kiln stop, showing good performance.
