Refractory lightweight high alumina thermal insulating fire brick

Description of High Alumina Insulating Refractory Fire Brick Annec Shuttle Kiln Thermal Insulating Fire Brick 2.0MPa

Light Weight High Alumina Brick, also known as high-aluminium heat
insulating brick, are used in building heat insulating walls or
heat preserving walls, which is basically for preserving or
insulating heat. Light weight high alumina bricks contain more than
48% alumina oxide. This kind of brick does not directly exposed to
high temperature inside kilns or furnaces, it only built closely to
the kiln wall as insulations. It is a good insulation refractory
material, which has a high compressive strength, low thermal
conductivity and good insulation quality.
 
High Alumina Insulating Refractory Fire Brick Annec Shuttle Kiln
Thermal Insulating Fire Brick 2.0MPa can be divided into three
process: Raw material, molding, burning.Generally, refractory brick
was molded by dry pressing. By means of mixing the material
uniformity in proportion and aging mixture some time. Then, pour
some powders into the module and dry pressing. After dry pressing,
the adobe need to pushed in the drying kiln to stoving or stay in
the air to drying. This progress will need about 3-5 days. After
this progress, then push the adobe into the tunnel furnace or
shuttle kiln to burning around 1300C. This progress will be need
about 5-7 days.
After burning, High Alumina Insulating Refractory Fire Brick Annec
Shuttle Kiln Thermal Insulating Fire Brick 2.0MPa will be packed in
pallet and leave the factory.

Features of High Alumina Insulation Brick
 
1. Small volume density.
2. Low thermal conductivity.
3. Excellent heat insulation.
 
Application of Light Weight High Alumina Brick
Light Weight High Alumina Brick is used in parts that is not
exposed to abrasions and high temperature of melted matters. They
should not be applied in environment that has a temperature higher
than 1350℃.
. As a low price refractory material, the light weight high alumina
bricks are applied in:
. Furnace Lining And Insulation Layers
. Ceramic Tunnel Kiln
. Roller Kiln
. Shuttle Kiln
. Heating Furnace & Coking Furnace In Iron And Steel Industry
. Other Thermal Equipment & Heat Treatment Lining
 
Packaging:
1. Strong packing will protect the goods from any possible damage
during transit.
2. Solid packing and overall stuffing can prevent the cases from
vibration and jarring.
3. We must take necessary precaution that the packing can protect
goods from pilferage or rain.
4. We can confirm that we take every possible precaution to ensure
that our products reach our customers all over the world in prime
condition.
