Definition:
lightweight bricks material/lightweight insulating silica bricks is also known as silica insulation brick. Lightweight refractories
with silica above 91% and bulk density below 1.2g/cm3. The
refractoriness and load softening temperature are not much
different from ordinary silicon bricks with the same composition.
However, due to the large number of pores, the compressive
strength, slag resistance, and corrosion resistance are not as good
as others silicon bricks, but the thermal shock resistance has been
improved.
Using finely divided silica as raw material, the critical particle
size is usually not more than 1mm, and the particles less than
0.5mm are not less than 90%.
General lightweight bricks material/lightweight insulating silica
bricks can be divided into two levels: the first grade can be used
in the top of the steel rolling heating furnace and the roof of the
silicate industrial kiln, and can be directly in contact with the
flame; the second grade is used in the general industrial kiln
Insulation. Applicable to: industrial furnaces such as coke ovens,
hot blast furnaces, glass melting furnaces and carbon calciners.
Generally, the bulk density of silicon heat insulation refractory
bricks is 0.9-1.1g/cm3, the compressive strength is 2.0-5.9MPa, and
the thermal conductivity is 0.35-0.42W/(m·K). It has excellent fire
resistance, lightweight bricks material/lightweight insulating
silica bricks softening temperature under load is close to 1620℃
for dense silica bricks, with only a small residual expansion, and
its thermal stability is better than dense silica bricks.
Therefore, siliceous heat-insulating refractory bricks can be used
for a long time under high temperature conditions (1500-1550°C)
without contact with molten slag, but they are especially suitable
for high-temperature hot-blast furnaces of large blast furnaces.
Thermal insulation of silica brick gas.
lightweight bricks material/lightweight insulating silica bricks Advantage:
(1) Insulation and heat insulation: During the manufacturing process of aerated concrete, tiny pores
are formed inside, and these pores form an air layer in the
material, which greatly improves the effect of thermal insulation
(2) Sound absorption and sound insulation: good sound absorption and sound insulation performance can create
high airtight indoor space for you. Provide you with a quiet and
comfortable environment.
(3) Small shrinkage value: The excellent material with a small shrinkage value ensures that
your wall will not crack.
(4) Impermeability: The pore structure of this product makes the capillary action
poor, and the water absorption and moisture conduction are slow.
The time required for the same volume of water absorption to
saturation is 5 times that of clay bricks.
(5) Environmental protection: no pollution during manufacturing, transportation and use,
protect cultivated land, save energy and reduce consumption, and
belong to green environmental protection building materials.
(6) Silica Lightweight Refractories Material is also a light-weight heat-insulating brick. It has a higher heat
resistance temperature than light-weight clay bricks. It can be
used in heat-insulating parts to reduce heat loss and increase the
efficiency of the melting process.
lightweight bricks material/lightweight insulating silica bricks Application:
lightweight bricks material/lightweight insulating silica bricks are also used in the partition walls of the carbonization and
combustion chambers of coke ovens, the regenerators and slag
chambers of open hearth furnaces, soaking furnaces, glass melting
furnaces, refractory materials and ceramic firing kilns. There are
also vaults and other load-bearing parts for kilns. It is also used
for the high-temperature load-bearing part of hot blast stove and
the top of acidic open hearth furnace.
