1780 Degree 77% High Alumina Refractory Bricks In Cement Rotary Kiln
High alumina refractory products are alumina silicate refractories with Al2O3 content more than 48%. Usually divided into three categories: first grade: Al2O3 content more than 75%; second grade Al2O3 content 60%~75%; third grade Al2O3 content 48%~60%.
Production process characteristics
Phosphate bound high alumina brick is a high alumina refractory made of high bauxite clinker as aggregate and fine powder, phosphoric acid or alumina phosphate as binder, which is formed by semi-dry pressing ,400℃~600℃ heat treatment.

High Alumina Phosphate Bricks Features
1. high strength
2. excellent heat stability
3. good chemical resistance
Application
1. High alumina phosphate bonded bricks compared with ceramics, the high-aluminum bricks have better anti-flaking properties, the phosphate high aluminum bricks are suitable for cement kiln, electric furnace roof, ladle and the like.
2. Phosphate high alumina brick is made of high quality high alumina bauxite, combined with dihydrogen phosphate and dried in a drying oven. Phosphate high alumina refractory bricks are mainly used in dry cement production kiln, rotary kiln, phosphorus chemical kiln. Phosphate high alumina bricks have high refractoriness, good wear resistance and high strength.
3. Phosphate high alumina bricks are widely used in cement kilns and can be used as pre-tropical, decomposition zones, transition zones, cooling zones as their linings. Phosphate bonded alumina bricks, can also be used as a lining in a cement kiln firing zone with a diameter of less than 3 meters.
4. Phosphate high alumina bricks are mainly used for calcining cement, bauxite, dolomite and other rotary kiln, lining of cooling machine, working layer of cement kiln, roof of steel making electric furnace.

Classification & Difference
1. Classification
Phosphate brick high alumina bricks are divided into phosphate bricks and phosphate wear bricks.
2. Difference
❉ Phosphate brick is used as a binder for phosphate, and phosphate wear-resistant brick is a binder of diammonium phosphate.
❉ Generally divided into resistant phosphate and high temperature phosphate. These two bricks are not much different because phosphates have better wear resistance.
❉ High-grade phosphate bricks are high-load soft phosphate bricks. Because phosphate bricks are combined with phosphoric acid, the load is generally low. Above 1300 ℃ ~ 1450℃.
