What are The Factors That Affect The Service Life of Aluminum Brick?

Aluminum brick is the basic refractory material used in high-temperature kilns in steelmaking, ধাতুবিদ্যা, রাসায়নিক শিল্প, ইত্যাদি. Therefore, the service life of high-alumina refractory bricks also affects the service life of the kiln.

Factors affecting the life of alumina brick

1. Working temperature: High-alumina refractory bricks are usually used in high-temperature environments. Exceeding their designed working temperature will cause an increase in thermal stress on the brick structure, thus affecting its lifespan.
2. Chemical corrosion: Bricks exposed to corrosive substances, such as acidic or alkaline media, metal melts, ইত্যাদি, will cause corrosion and wear of the bricks.
3. Mechanical impact: The brick body may be hit or squeezed by objects during use, which may cause the brick body to crack or peel off.
4. Strong thermal shock stability: High-alumina refractory bricks are prone to thermal stress in a working environment with rapid temperature rise and fall, thus affecting the stability of their structure.
5. Brick quality: The materials and processes used to make high-alumina refractory bricks will also affect their lifespan. Better quality high alumina refractory bricks usually have a longer service life.
6. Correct installation and maintenance: Correct installation and maintenance can slow down the wear and aging of high alumina refractory bricks. Regular inspection and maintenance can extend the life of bricks.
7. Brick design and shape: Properly designed brick shape and structure can reduce the concentration of thermal stress, thereby extending its life.
8. Usage environment: The working environment where the brick is located is also an important factor.

How to choose suitable alumina brick?

Aluminum brick is often used as linings in kilns at high temperatures. When choosing a suitable kiln lining, you must understand the characteristics of high-alumina refractory bricks and make appropriate selections based on the working environment and usage mechanism of the kiln. Otherwise, it is easy to make the wrong choice and cause losses.
