                         High Alumina Refractory Brick
Product Description

 Definition:

 

Clay brick is refers to the Al2O3 content is 30% ~ 40% aluminum silicate clay products. Clay brick is made of soft clay and 50% and 50% of hard clay grog, ingredients required by certain granularity, after forming, drying, burning under the high temperature of 1300 ~ 1400 °C.

 

Composition:

 

The main mineral composition of clay brick kaolinite (2 sio2, Al2O3 · 2 h2o) and 6% ~ 7% of impurities (potassium, sodium, calcium, titanium, iron oxide).

 

Advantage:

 

1.Low thermal conductivity

 

2.Low thermal expansion

 

3.Excellent oxidation resistance 

 

4.Excellent corrosion resistant

 

5.long duration

 

Application: 

 

1.Good lining refractory materials in Aluminum electrolysis cell,furnace,kiln,incinerators, and reactors.

 

2.As Tuyere combined bricks or other combined blocks in Iron&steel industry.

 

3.Used as Kiln shed board, beams,slide push board, sagger.

 

Performance:

 

Thermal performance is good, resistance to thermal shock and wear corrosion resistance to spalling characteristics such as high mechanical strength low creep.
