MULLITE INSULATION BRICK PROFESSIONAL MANUFACTURER

Mullite insulation brick introduction:

Mullite insulation brick is one kind of high alumina refractory brick which the main crystalline phase is mullite (3Al2O3·2SiO2. The content of alumina is between 50%-80%,Mineral composition in addition to mullite, also have  glass phase and quarts and small amount corundum.According to the difference application temperature the mullite insulation brick can be divided into diffrnence grade, 1350℃ mullite insulation brick, 1450℃ mullite insulation brick, 1550 mullite insulation brick.

Mullite insulation brick characters:

1.Low thermal conductivity with good thermal insulation effect;
2.Low melting, low thermal conductivity, energy saving effect is obvious
3.Low impurity content,it conetent very lower iron and oxides such as alkali metal make mullite insulation brick with high refractoriness，the hihger content of alminum makes it keep good perfermance in reducing atmosphere.
4.Mullite insullation brick has high compressive strenth in hot state.

Mullite insulation brick application:
It is suitable for hot lining and backing of various industrial furnaces in metallurgy, petrochemical, building materials, ceramics, machinery and other industries.Such as: cracking furnace, reformer, heating device, refining device, regeneration device, hot air furnace, heating furnace, soaking pit furnace, heat treatment furnace, resistance furnace, tunnel kiln, roller kiln, shuttle kiln, bell jar kiln, glass pool kiln, etc.
