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.
Product Details
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℃.
