FAQs of High Alumina Bricks:
Q: How are High Alumina Bricks used in industrial settings?
A: High Alumina Bricks are primarily used for lining furnaces, kilns, and incinerators in industries like steel, cement, glass, and ceramics. Their capacity to resist high temperatures and chemical corrosion ensures safe and long-lasting protection for thermal equipment.
Q: What benefits do High Alumina Bricks offer over traditional fire clay bricks?
A: High Alumina Bricks provide superior thermal stability, higher mechanical strength, reduced porosity, and enhanced resistance to slag and chemical attacks compared to traditional fire clay bricks. These attributes translate to longer service life and reduced maintenance costs in demanding environments.
Q: When should you choose High Alumina Bricks with higher alumina content?
A: Bricks with higher alumina content (up to 90%) are preferable for extremely high-temperature applications and in areas prone to severe chemical or slag attacks. Selecting the appropriate alumina level depends on the specific operating conditions and desired durability.
Q: Where is the best place to install High Alumina Bricks for optimal performance?
A: High Alumina Bricks perform best in zones exposed to intense heat and corrosive environments, such as furnace roofs, combustion chambers, kiln hoods, and incinerator linings. Their robust characteristics safeguard against material degradation in these critical areas.
Q: What is the standard manufacturing process for these bricks?
A: These bricks are produced through a controlled machine-made process using selected high alumina raw materials, pressed and then sintered at high temperatures to achieve low porosity and high density, ensuring consistent quality and performance.
Q: How does low porosity in High Alumina Bricks benefit end-users?
A: With apparent porosity between 1822%, these bricks have lower water absorption ( 5%) and enhanced resistance to slag and corrosive agents. This promotes greater durability and efficiency by minimizing material wear and thermal losses during service.
Q: Which certifications and standards do High Alumina Bricks comply with?
A: These bricks conform to national and international standards such as IS: 6, IS: 8, and ASTM C27, assuring users of their quality, reliability, and suitability for high-performance applications in various industries.
