Feature
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.
Applications:
Corundum Mullite Dense Brickcan 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,ANNEC 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.
Zhengzhou Annec CO., Ltd. was founded in 2003, and has been a
