What are the factors, affecting the service life of aluminum bricks?

Aluminum brick is the main fireproof material, used in high temperature steelmaking furnaces, metallurgy, chemical industry, etc.. Thus, The service life of high alumina fire bricks also affects the service life of the kiln.

Factors affecting the life of alumina brick

1. Operating temperature: High alumina content fire bricks are commonly used in high temperature environments. Exceeding the design operating temperature will increase the thermal load on the brick structure, what will affect its service life.
2. Chemical corrosion: Bricks, exposed to aggressive substances, such as acidic or alkaline environments, metal melts, etc., cause corrosion and wear of bricks.
3. Mechanical impact: During use, the brick body may be hit or squeezed by foreign objects., which can lead to cracking or peeling of the brick body.
4. High resistance to thermal shock: Refractory bricks with high alumina content are subject to thermal stress in a working environment with rapid rise and fall in temperature, which affects the stability of their structure.
5. Brick quality: Materials and processes, used to make high alumina fire bricks, also affect their service life. Higher quality high alumina content firebricks usually have a longer service life.
6. Correct installation and maintenance: Proper installation and maintenance can slow down the wear and aging of high alumina fire bricks. Regular inspection and maintenance can extend the life of the brick.
7. Brick design and shape: Properly designed brick shape and structure can reduce thermal stress concentrations, thereby extending its service life.
8. terms of Use: Working environment, which contains the brick, is also an important factor.

How to choose suitable alumina brick?

Aluminum brick is often used as a lining in ovens at high temperatures. When choosing a suitable kiln lining, you must understand the characteristics of high alumina fire bricks and make your selection accordingly, based on operating conditions and the mechanism for using the furnace. Otherwise, it is easy to make the wrong choice and suffer losses.
