Sintered Mullite Insulation Refractory Brick Lightweight Refractory Brick JM-23

Sintered Mullite Insulation Refractory Brick Lightweight Refractory Brick JM-23

Lightweight brick is a high-quality refractory insulation material with light weight, low thermal conductivity, heat insulation and high compressive strength for high-temperature furnaces. Lightweight bricks are mainly used for hot blast stove top, blast furnace chimney and bottom, glass furnace regenerator, ceramic high temperature furnace lining, etc.
Lightweight bricks use mullite as the main crystal phase, containing about 65-75% alumina. Mullite insulation bricks have high refractoriness, up to 1790°C. Its apparent initial softening temperature is about 1600-1700°C. Its cold compressive strength is about 70~260MPa.
Mullite insulation bricks are divided into different models such as 1350 light weight bricks, 1450 light weight bricks and 1550 light weight bricks according to different use temperatures, and are divided into light weight mullite bricks and heavy weight mullite bricks according to different bulk density.

Lightweight brick is a high-quality high-temperature resistant material with the following excellent characteristics

Performance:
Low thermal conductivity and low heat capacity
High purity and low impurity content
Excellent high temperature strength
good thermal shock resistance
low expansion coefficient
Strong acid and alkali corrosion resistance
Features of lightweight mullite insulation bricks:
1. Excellent compressive strength
2. Excellent thermal stability
3. Low thermal conductivity
4. Low heat storage
5. High aluminum, low iron and alkali flux content
6. Accurate size
7. Design packaging
