High alumina brick is a common type of refractory material, and there are various specifications and models available. Some commonly used specifications and models are as follows:
1、HA-55 high alumina brick
with an alumina content greater than 55%, it has good high-temperature strength and abrasion resistance.
2、HA-65 high alumina brick
with an alumina content greater than 65%, it has higher mechanical strength and better thermal shock resistance than HA-55 brick.
3、HA-75 high alumina brick
with an alumina content greater than 75%, it has excellent mechanical strength, abrasion resistance, and resistance to corrosion by acid and alkali.
4、HA-80 high alumina brick
with an alumina content greater than 80%, it has very high mechanical strength and excellent resistance to corrosion and erosion by acid and alkali.
5、HA-85 high alumina brick
with an alumina content greater than 85%, it has extremely high mechanical strength and excellent resistance to high temperature, corrosion, and erosion.
6、HA-90 high alumina brick
with an alumina content greater than 90%, it has the highest mechanical strength and excellent resistance to high temperature, acid and alkali corrosion, and erosion.
These high alumina bricks are suitable for different high-temperature applications, such as blast furnaces, hot blast stoves, rotary kilns, and glass furnaces. Different specifications and models can be selected according to the specific requirements of the application.
