About High Alumina Bricks
High Alumina Bricks
Refractory material like high Alumina Bricks can be purchased from us at market leading price. This material as the very name implies is mainly made of Al2O3. This material given to its high strength, thermal stability and resistance to erosion, corrosion and wear, is widely used in glass furnace, refining furnace, blast furnace, and other kinds of furnace. Industries that demand the high alumina bricks are majorly refractory, refining, metallurgy, mining and cement. Customers are free to select the right grade of bricks based on the application.
Exceptional Thermal and Mechanical Properties
With high refractoriness under load (RUL) exceeding 1450C, and a service temperature up to 1700C, these bricks maintain stability and strength even in extreme conditions. Their superior cold crushing strength (>50 MPa) and high abrasion resistance ensure long-lasting structural integrity in industrial applications.
Versatility in Shape and Application
Offered in standard, arch, and custom shapes, the bricks are suitable for various installations. Their excellent dimensional stability and smooth finish enable use in steel plants, cement kilns, glass furnaces, and incinerators, meeting diverse requirements for lining and insulation.
Reliable Quality and Export Packaging
Certified under ISO 9001:2015, every batch undergoes stringent quality control. Bricks are securely packed on wooden pallets or export-worthy packaging for safe transport, supporting international supply and robust logistics.
FAQ's of High Alumina Bricks:
Q: How are high alumina bricks beneficial for industrial furnaces and kilns?
A: High alumina bricks offer remarkable thermal stability, high abrasion resistance, and superior compressive strength, ensuring reliable performance and longevity in furnaces, kilns, and similar high-temperature installations.Q: What is the standard size available, and are customized dimensions offered?
A: The standard size of our high alumina bricks is 230mm x 114mm x 76mm. We also provide custom sizes and shapes to meet specific installation and application requirements.Q: Where can these bricks be used in the industry?
A: They are widely utilized for lining furnaces, kilns, incinerators, steel and cement plants, glass industries, and foundries-anywhere high-temperature resistance and strength are essential.Q: What process ensures the bricks' high refractoriness and mechanical strength?
A: Our bricks are manufactured using high-purity alumina, advanced firing techniques, and tight quality control. This process guarantees refractoriness above 1450C and compressive strength exceeding 50 MPa.Q: What is the advantage of the brick's thermal expansion and porosity characteristics?
A: With controlled thermal expansion (30~35 107/C) and low apparent porosity (18-23%), these bricks provide exceptional dimensional stability and reduce heat loss, enhancing energy efficiency and safety in high-temperature environments.Q: How are the bricks packaged for export and transportation?
A: Bricks are packed on sturdy wooden pallets using export-worthy materials, ensuring they arrive safely and reliably at international destinations.
