alumina insulating fire bricks for ceramic kiln
customized Size Refractory Insulation Bricks light weight high
alumina insulating fire bricks for ceramic kiln is an ideal
insulating refractory refractory material, with advantages of high
strength, low thermal conductivity, good insulation property and
low price. For various industrial kilns & furnaces, it is a
kind of essential refractory for energy saving and temperature
preservation.
customized Size Refractory Insulation Bricks light weight high
alumina insulating fire bricks for ceramic kiln is also called
refractory insulating brick. It contains more than 48% Ai2O3 and
mainly consists of mullite and glass phase or corundum. It is
usually made of high bauxite and a small amount of clay. After the
raw materials are grounded, it is made into mud. Then it is cast
and molded and fired at 1300~1500℃. Sometimes industrial alumimum
is used to replace bauxite. Inorganic matter is added as ignition
loss substance in order to increase the porosity of the refractory.
Feature Of refractory insulating brick :
1. It has advantages with small bulk density, high cold crushing
strength, and high refractoriness under load, small dimension
tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in
various insulating refractory bricks.
3. It can reduce the total weight of furnace body and the thickness
of furnace wall effectively, improve heat efficiency, lower energy
consumption, improve work conditions and production efficiency, and
considerable economic benefit can be obtained.
Production Process of refractory insulating brick:
refractory insulating brick:Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment
customized Size Refractory Insulation Bricks light weight high
alumina insulating fire bricks for ceramic kiln has such advantages
as high porosity, good insulation effect, high mechanical
intensity, low thermal refractory fiber board conductivity and long
service life. It has high cold crushing strengh,size precision and
holds the most stable and lowest thermal conductivity of all
insulating refractory brick at present. Its maximum insulating
castable service temperature is 1350℃. Thermal efficiency and
working condition can be improved, energy consumption can be
lowered, productivity and significant economic results can be
achieved.
customized Size Refractory Insulation Bricks light weight high
alumina insulating fire bricks for ceramic kiln is characterized by
low bulk density. The total weight of the furnace body and walls
thickness can be reduced effectively.
It has found a wide application in ceramics tunnel kiln, roller
kiln, shuttle kiln, coking furnaces of iron and steel industry and
other thermal equipment. It is mainly used in lining and insulating
layer of areas without strong erosion by high temperature melts.
When in direct contact with flame, the surface contact temperature
can not be higher than 1350℃.
