The Al2O3 content of the Fire clay Brick is from 30-48%.During the
manufacturing,first mix the clay chamotte with refractory clay
powder,then prepared with clay aggregate into dry mud,high pressure
molding,sintering at about 1400C.Under high temperature,the fire
clay bricks show weakly acidic,and the ability of resistance to
alkaline slag erosion is poor,but with the increase of the content
of Al203,the thermal stability of fire clay bricks is better than
silica brick, magnesia brick and so on.
Fireclay brick is made from clinker clay by mixing, forming,
drying, sintering and matching characterized by good resistance to
corrosion and abrasion, good thermal shock resistance, good
spelling resistance, high mechanical strength, good volume
stability under high temperature.
Advantage
1. Good resistance to corrosion and abrasion,
2. Perfect thermal shock resistance,
3. Good spalling resistance,
4. High mechanical strength,
5. Good volume stability under high temperature,
6. Excellent thermal performance, and acid resistance.
Application:
1) Cement and other building materials industry kiln back
insulation;
2) Petrochemical, metallurgical, ceramics, glass industry, the
furnace lining insulation;
3) Heat treatment furnace backlash insulation;
4) Non-ferrous metal industry back insulation;
5) High temperature reaction, heating equipment back insulation.
Low porosity clay bricks can be applied to steel, nonferrous
metals, glass, cement, ceramics, pertrifaction, machinery, boiler,
light industry, electric power, war industry and other economic
filed, which is the indispensable basic material to ensure above
production running and technological development, it plays an
incomparable important role in the development of high temperature
industrial production.
