White Mullite Insulating refractory brick:
White Mullite Insulating refractory brick for special ceramic sintering furnace lining, mainly based on aluminum silicate-based refractory materials, with some excellent performance, (especially high temperature creep performance) living in natural raw materials production Of the high aluminum products first.
White Mullite Insulating refractory brick for special ceramic sintering furnace lining,Mullite composition AL203 in about 79%, Si02 in 21% is more appropriate, but there are a certain amount of raw materials in the impurity composition, at high temperatures will cause the composition of the composition, so as the impurity composition increases, will make vitreous and corundum And the molybdenum is formed into coarse grain structure, which makes the porosity of the product increase, the thermal shock stability and corrosion resistance are reduced, and cracks are likely to occur.
White Mullite Insulating refractory brick for special ceramic sintering furnace lining ccording to the different use of temperature production of multiple grades of mullite lightweight insulation brick is divided into WAM23 / WAM26 / WAM28, the use of temperature range from 1100C-1650C, the ratio of each product is specially designed to meet the different thermal and Physical requirements.
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:
1 | Metallurgy industry |
2 | Petrochemical industry |
3 | Ceramics industry |
4 | Aluminum industry |
5 | Glass industry |
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.
