Characteristic of Alumina Brick
Good high temperature resistance
High alumina refractory bricks can withstand high temperature sintering, so they are widely used in high temperature industrial equipment lining, flue, furnace roof, furnace wall and other parts.
Strong corrosion resistance
High alumina refractory bricks have good acid and alkali corrosion resistance, and are suitable for refractory requirements in acidic, alkaline and neutral environments.
Good wear resistance
High alumina fire bricks have good wear resistance and can cope with the wear of high-speed flue gas and solid particles.
Strong cold and heat shock resistance
High alumina brick have good cold and heat shock performance, and can withstand sharp temperature changes without breaking.
Application Industries of Alumina Brick
Metallurgical Industries
In metallurgical industries, high alumina bricks are widely used in blast furnaces. Their ability to endure high temperatures and resist slag erosion makes them vital for efficient metal production.
Cement Manufacturing
The cement industry utilizes high alumina bricks in their kilns. The bricks' thermal stability and resistance to chemical attack enhance the longevity and performance of the kiln, ultimately affecting the quality of the cement produced.
Glass Production
In the glass manufacturing sector, high alumina bricks serve critical roles in melting furnaces and refining applications. Their ability to withstand thermal shock and resist chemical corrosion ensures consistent output quality.
Precautions for Using Alumina Brick
Chemical composition
High alumina refractory bricks have different compositions, such as alumina content of 48%, 60%, 70%, 80% and 90%. The choice of composition depends on the particular application and desired properties.
Brick Shapes and Sizes
Manufacturers offer high alumina refractory bricks in a variety of shapes and sizes to suit different applications. Choosing the proper brick shape and size is critical for optimal performance and ease of installation.
