Description of Factory Supply Refractory Alumina Silica Fire Brick Furnace Refractory Brick For Coke Oven And Furnaces
Alumina silica fire bricks are a type of refractory brick that is
made from a mixture of alumina and silica. They are made by firing
a mixture of alumina and silica at a high temperature, which
creates a strong and durable brick. Alumina silica fire bricks are
known for their high refractoriness, good load-bearing capacity,
and resistance to thermal shock.
Application of Refractory Alumina Silica Fire Brick
Alumina silica fire bricks are used in a wide range of
high-temperature applications, including:
Blast furnaces
Open hearth furnaces
Electric arc furnaces
Rotary kilns
Cement kilns
Incinerators
Glass furnaces
Petrochemical furnaces
Alumina silica fire bricks are available in a variety of shapes and
sizes to meet the specific needs of different applications. They
can be cut and shaped to fit any application.
Advantages of using alumina silica fire bricks:
High refractoriness: Alumina silica fire bricks can withstand
temperatures up to 1750°C.
Good load-bearing capacity: Alumina silica fire bricks are very
strong and can withstand heavy loads.
Resistance to thermal shock: Alumina silica fire bricks can
withstand rapid changes in temperature without cracking or
deforming.
Good chemical resistance: Alumina silica fire bricks are resistant
to corrosion from acids, alkalis, and other chemicals.
Good thermal conductivity: Alumina silica fire bricks have good
thermal conductivity, which allows them to heat up and cool down
quickly.
Alumina silica fire bricks are a versatile and durable refractory
material that is suitable for use in a wide range of
high-temperature applications. They are a cost-effective and
reliable solution for many different industries.
Here are some additional details about alumina silica fire bricks:
1.Alumina silica fire bricks are typically made from a mixture of
60-70% alumina and 30-40% silica.
2.The alumina content in the brick determines its refractoriness
and load-bearing capacity. The silica content in the brick
determines its resistance to thermal shock and chemical resistance.
3.Alumina silica fire bricks are typically manufactured in a
variety of shapes, including bricks, blocks, tiles, and shapes.
4.Alumina silica fire bricks are typically installed using a
refractory mortar.
5.Alumina silica fire bricks should be inspected regularly for
signs of wear and tear.
If you are considering using alumina silica fire bricks in your
application, please consult with a qualified refractory engineer to
ensure that you are selecting the right brick for your needs.
