Overview of High Alumina Bricks

High alumina bricks are a class of refractory products with alumina content ranging from 48% to 99%. These bricks are known for their excellent thermal stability, mechanical strength, and resistance to chemical attack, making them suitable for various high-temperature applications.

Types of High Alumina Bricks

High alumina bricks can be classified based on alumina content and special properties:

1. By Alumina Content

   • Grade I High Alumina Bricks
     • Composition: Exceeding 75% Al2O3.
     • Properties: Highest resistance to heat, corrosion, and wear.
     • Applications: Cement kilns, glass furnaces, and other high-temperature environments.
   • Grade II High Alumina Bricks
     • Composition: 60-75% Al2O3.
     • Properties: Good balance between performance and cost.
     • Applications: Industrial furnaces, boilers, incinerators.
   • Grade III High Alumina Bricks
     • Composition: 48-60% Al2O3.
     • Properties: Most affordable with adequate performance for less demanding applications.
     • Applications: Suitable for moderate-temperature settings.

2. By Special Properties

   • Conventional High Alumina Bricks
     • Properties: Good all-around performance for various applications.
   • Low Iron High Alumina Bricks
     • Properties: Made with low-iron raw materials, resistant to slag attack.
     • Applications: Crucial for certain glass-making processes.
   • Insulating High Alumina Bricks
     • Properties: Low thermal conductivity, resist heat flow.
     • Applications: Lining furnaces and kilns to retain heat.

Enhanced Properties and Industrial Applications

Our high alumina bricks are engineered to provide superior performance in extreme conditions. Their high refractoriness and mechanical strength make them indispensable in industries such as steel, cement, and non-ferrous metal production. These bricks offer excellent resistance to thermal shock and chemical attack, ensuring longevity and reliability in critical applications.

In the steel industry, our premium high alumina bricks are highly valued for their ability to withstand the harsh conditions of furnaces and ladles. In cement production, standard high alumina bricks provide the necessary durability and resistance to alkali attacks, ensuring efficient kiln operations.
