99% Al2O3 Bubble Alumina Brick for Industrial Ceramic Furnace Kiln
Alumina Bubble Brick uses the alumina hollow ball as the main raw
material, high-performance powder as additives, and organic
material as the temporary binding agent. After mixing, drying,
forming, firing at high temperature shuttle kiln, it is made. The
material is widely used in carbon black furnace, gasifier, gas
furnace, hydrogen furnace, as well as shuttle kilns and other
high-temperature furnace equipment. Products, dimensions, physical
and chemical indicators of useful life are up to customers'
requirements. The company produces lightweight insulation
refractory material with high purity, mechanical strength and low
thermal conductivity. The material is fireproof and anti-spalling.
It can be used as insulation lining and the high-temperature
furnace lining of other industries.
alumina bubble brick is made of alumina hollow ball as raw
material, high-performance powder as additive, and organic material
as the temporary binding agent, after mixing, drying, forming,
firing at high temperature in shuttle kiln, the whole process is
finished.
The quality of alumina bubble brick has reached or exceeded the
level of similar products at home and abroad.
Alumina Bubble Brick Features:
1. Excellent thermal shock resistance, low thermal conductivity and
good performance of insulation.
2. High temperature resistance as Al2O3 content is≥85%.
3. Reduce furnace weight as there are amount of closed pores in
alumina bubble brick.
4. Strong ability to resist erosion of gas and slag.
5. Direct contact with flame.
