high refractoriness Rotary kiln high-alumina brick refractory
material
Rotary kiln fire brick
During the calcining materials, in order to protect the rotary kiln
body from the high temperature, the high quality refractory
materials are used. Refractory bricks are the most frequently used
materials in all refractory materials, including high-alumina
brick. The high-alumina brick has its own advantages and uses in
rotary kiln equipment.
High-alumina brick is a neutral refractory material with alumina
content of more than 48%, which is formed and calcined by alumina
or other raw materials with high alumina. It has the advantages of
thermal stability, high refractoriness in more than 1770 ℃, better
slag resistance. It is used to lay the lining of steel furnace,
glass furnace, cement rotary kiln, etc.
High alumina refractory brick has the following features:
1.High refractoriness under load.
2.Good thermal shock resistance.
3.Good corrosion resistance.
4.Good spalling resistance and wear resistance.
5.High mechanical strength.
6.Low creep rate at High temperature.
This high alumina brick material is used in the lining of general
rotary kiln, and in production, it is also used in the production
of various kinds of furnaces. Because its use effect is remarkable,
the alumina brick commonly is higher than ordinary firebrick on
sale price. In addition, for this kind of high alumina brick
material and the material of silicon brick, it has better high
temperature resistance, so in use, its fire resistance is better.
And the high alumina brick has the properties of corrosion
resistance and anti-acid and alkali resistance. Due to the
different materials of each refractory brick, it is also different
in terms of specific use performance. The performance of different
refractory materials is somewhat different in use, so different
kinds of firebricks should be processed and used according to
specific utility. The use of high alumina brick can be used in
different parts of rotary kiln equipment for a better high
temperature resistance effect.
Features
1. Low bulk density, low thermal conductivity, good thermal
insulation performance.
2. Refractory category allow direct contact of fire, suitable ofr
various atmosphere
3. Good integrity with furnace lining, long service life, easy
operation, could be shaped freely
4. Product specification: standard form, normal standard, shaped
and special shaped bricks.
5. Can be used in various kilns because of its cheapness and
general tray package. Among all of the refractory materials, it is
the most widely used.
