Mullite Insulation Brick Description:
High temperature mullite insulation bricks for sale are made from good quality and superior raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chemical demands.
Mullite Insulation Brick Advantage:
1. Low thermal conductivity
2. High cold crushing strength
3. Perfect Energy saving
4. Stable volume
5. Excellent heat insulation
6. High intensity for pressure
7. Good thermal shock stability
Mullite Insulation Brick Application:
Performances:
1. Low heat conductivity, with good thermal insulation effect
2. Low hot melting, due to low heat conductivity, it accumulates little heat to get obvious energy-saving in intermittent operation.
3. Low impurity content and low content of iron oxide & alkali metal oxide realize high refractoriness. High Al2O3 content makes it keep good performance under reducing atmosphere.
4. High thermal compressive strength
5. Accurate size increases construction speed, decreases fire clay usage, ensures strength and stability of masonry, prolongs the life span of lining.
6. It can be processed into special shapes to reduce brickwork amount and paving seam.
Application:
Mullite insulating brick can be used in high temperature kiln lining. Currently, it is widely used roof of hot-blast furnace, body and bottom of blast furnace, regenerative chamber of glass melting furnace, ceramic kiln, blind angle furnace lining of petroleum cracking system, shuttle kiln, roller kiln, linings of glass and petrochemical engineering furnaces.
In addition, in order to meet the production requirements of more clients and kilns, KERUI develops new products of different textures and shapes on the basis of originals, such as poly-light mullite brick tile, poly-light corundum brick, poly-light silicon brick, fire clay insulating brick, etc.
