mullite insulation brick characteristics:

1. Low thermal conductivity, with good heat insulation effect;

2. Low hot melt, due to low thermal conductivity, mullite series lightweight thermal insulation bricks accumulate very little heat energy, and the energy saving effect is obvious in intermittent operation;

3. Low impurity content has very low iron box alkali metal oxide content, therefore, high refractoriness; high aluminum content makes it still maintain good performance in reducing atmosphere;

4. High compressive strength in hot state;

5. Appearance size, speed up the masonry speed, reduce the amount of refractory mud used, ensure the strength and stability of the masonry, thereby extending the life of the lining; 6. It can be processed into a special shape to reduce the number of bricks and joints.

Mullite insulation brick use:

Mullite insulation brick can be directly used for high temperature furnace lining, has been widely used in shuttle kiln, roller kiln, glass and petrochemical furnace lining.
