The Alumina Brick Applications
Alumina or high alumina bricks are bricks https://rsrefractoryfirebrick.com/high-alumina-bricks/ that are made to provide protection against high heat. These bricks are employed in a variety of applications. The most prevalent for these particular bricks is glass melting tanks. They are sometimes called fire bricks https://rsrefractoryfirebrick.com/fire-brick-for-sale.
Alumina bricks https://rsrefractoryfirebrick.com/alumina-refractory-bricks will also be employed to line fireplaces, furnaces, and kilns. Besides being immune to high heat temperatures they are able to also hold onto their heat for longer periods. This enables them to provide greater efficiency for such things as furnaces or fireplaces.
These bricks are comprised of about one half alumina. This will make them similar in makeup to fireclay bricks. Fireclay bricks https://rsrefractoryfirebrick.com/fire-clay-bricks-for-sale have only about 40 % alumina. The exact content in the alumina has much with regards to the quality of the brick. Alumina bricks do not possess porous surfaces hence they also expand when they are open to high heat temperatures. They may withstand temperatures well over 2900 degrees F.
Whilst they can expand they are not the initial option for high-temperature primary bricks. These are, however, a lot better designed for backup bricks. The higher the content in the alumina the better from the bricks are for industrial uses. They are also sometimes manufactured from alumina and chrome which makes them great for industrial uses that may expose the bricks to both cold and hot temperatures. They can be immune to acidic slags.
The alumina in the bricks allows them to have good load bearing capabilities. Again, this is what causes them to be last in even the toughest conditions in industrial uses. So they can be regarded as high alumina they must be made mostly of lower alumina silicates or clay.
These bricks have excellent load resistance in industrial uses when they contain some mullite crystals. They may be purchased online https://rsrefractoryfirebrick.com from quality manufacturers Rongsheng.
