Alumina Refractory Cement Kiln Lining Material Weight 0.8 High Aluminum Brick
Definition:
Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick generally refer to refractory bricks with a density less than 1.3
g/cm3. Due to the characteristics of low density, high porosity,
small thermal conductivity, good thermal insulation and certain
compressive strength, light-weight refractory bricks have been
widely used in heat treatment equipment.
Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick is also known as high aluminum insulation brick. Lightweight
refractory material with alumina content above 48%, mainly composed
of mullite and glass phase or corundum. The bulk density is 0.4 to
1.35 g/cm3. The porosity is 66%~73%, and the compressive strength
is 1~8MPa. Good thermal shock resistance.
Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick is a kind of insulation material adopting organic
matter as ignition loss substance in order to increase the porosity
of refractory, which has such advantages as high porosity, small
volume density, good insulation effect, high mechanical intensity,
small thermal conductivity and long service life. For various
industrial kilns & furnaces, it is a kind of essential
refractory for energy saving and temperature preservation
.
Advantage:
1. Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick has advantages with small bulk density, high cold crushing
strength, and high refractoriness under load, small dimension
tolerance and good thermal shock resistance.
2. Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick has the lowest and most stable thermal conductivity in various
insulating refractory bricks.
3. Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick 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.
Application:
Alumina Refractory Cement Kiln Lining Material Weight 0.8 High
Aluminum Brick ,also know as high alumina insulation brick. The lining and the
heat insulation layer of the kiln ,and the part of the erosion of
the material without strong high temperature meiting .The surface
contact temperature shall not be higher than 1350℃.
High qulity high alumina bricks can be used in direct contact with
the flame of the furnace lining ,but should not be used directly by
slay erosion occasions.
