JM Series High-end Insulation Refractory Brick for Lining of High Temperature Industrial Furnace
The Description:
High alumina refractory with mullite (3Al2O3·2SiO2) as the main crystalline phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the lower alumina content also contains a small amount of glass phase and cristobalite; Higher alumina content also contains a small amount of corundum. Mullite insulation brick can be directly used in high-temperature kiln lining, has been widely used in shuttle kiln, roller kiln, glass and petrochemical kiln lining

Characteristics of JM28 Mullite insulation brick:
1.Low thermal conductivity, with good thermal insulation effect;
2. Low hot melt, due to low thermal conductivity, mullite series light heat insulation bricks accumulate little heat energy, energy saving effect is obvious in intermittent operation;
3. Low impurity content with very low iron box alkali metal oxide content, therefore, high refractoriness; High aluminum content makes it maintain good performance in reducing atmosphere;
4. High compressive strength in hot state;
5. The appearance size is accurate, speeding up the masonry speed, reducing the use of refractory mud, ensuring the strength and stability of the masonry, thus extending the life of the lining;
6. It can be processed into special shapes to reduce the number of bricks and joints.
