Mullite Light Brick - RS Refractory Manufacturer

The mullite light brick has an AL2O3 content of 50% to 85%. It is a new type of high-quality thermal insulation and refractory material with mullite as the main crystal phase and the combined phase.

Because mullite has excellent high temperature mechanical properties and chemical stability. Therefore, mullite lightweight bricks have excellent properties such as high-temperature structural strength, low high-temperature creep rate, small thermal expansion coefficient, strong chemical resistance and good thermal shock resistance. It can be used as the lining of the kiln working surface that directly contacts the flame, which can significantly improve the energy saving effect of the kiln.

Characteristics of mullite light brick:

1. Low thermal conductivity and good thermal insulation effect;

2. Low hot melt. Due to the low thermal conductivity, the mullite series of light heat-insulating bricks accumulate little heat energy, and the energy saving effect is obvious in intermittent operation;

3. Low impurity content has very low iron box alkali metal and other oxide content, therefore, high fire resistance; higher aluminum content makes it maintain good performance under reducing atmosphere;

4. High thermal compressive strength;

5. Accurate appearance dimensions, speed up the masonry, reduce the use of refractory mud, ensure the strength and stability of the masonry, thereby extending the life of the lining;

6. Can be processed into special shapes to reduce the number of bricks and joints.

Use of mullite light brick:

The mullite light brick, one kind of the Insulating Fire Brick, can be used as the lining of the kiln working surface that directly contacts the flame, which can significantly improve the energy saving effect of the kiln.
