Refractoriness 1780℃ 230x114x65mm High Alumina Bricks

Refractoriness 1750℃ 230x114x65mm High Alumina Bricks

Introduction of High Alumina Bricks

High alumina brick is a kind of alumina-silicate refractory material with the content of alumina oxide more than 48%. It is calcined and formed by the raw material of bauxite or the material with a high content of AL2O3. High thermal stability, the refractoriness is more than 1780℃.

Features of High Alumina Bricks

1. high strength
2. good wear resistance
3. good chemical resistance
4. good thermal shock resistance
5. high load softening temperature
6. alkali resistance is better than clay brick, high alumina brick

Specification of High Alumina Bricks

Application of High Alumina Bricks

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 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.
3. 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℃.
