Blast Furnace 1.2g High Temperature Insulation Bricks
Definition:
Light Weight Silica Fire Brick refer to heat-insulating refractory products made of silica as the
main raw material and with an SiO2 content of not less than 91%. In
addition to the thermal insulation properties of Insulating silica
bricks, it maintains the characteristics of silicon bricks to a
large extent. The starting temperature of load softening is high,
and the volume expands slightly during the heating process, which
enhances the integrity of the kiln. The manufacture of siliceous
Insulating silica bricks uses finely pulverized silica as the raw
material, adding part of the waste silica bricks or waste siliceous
Insulating silica bricks powder, mineralizers and burnout
additives. Add water to the mixer according to a certain proportion
to mix into a mud, which is formed by mechanical or manual molding.
After the brick is dried, the residual moisture is less than 0.5%
before it can be loaded into the kiln. In order to prevent the
violent volume expansion due to the polycrystalline transformation
of SiO2, causing cracks in the product, a slower temperature rise
and fall speed are required during firing.℃.
Advantage:
(1) Light weight: using this product in construction can reduce the weight of the
building and greatly reduce the comprehensive cost of the building.
(2) 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
(3) 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.
(4) Small shrinkage value: The excellent material with a small shrinkage value ensures that
your wall will not crack.
(5) 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.
(6) 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.
(7) Light Weight Silica Fire Brick 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.
Application:
Light Weight Silica Fire Brick are widely used for hot blast furnace, coke oven, and glass
furnace. The products can be made according to customers'
requirement.
