【Frequently Asked Questions】

Q: In which industries are AZS zircon corundum bricks mainly used?
A: AZS zircon corundum bricks are mainly used in the melting pool and flow hole of glass furnaces, and are also used in key refractory areas of high-temperature industries such as metallurgy and ceramics.

Q: How to clean stains on the surface of AZS zircon corundum bricks?
A: When cleaning stains on the surface of AZS zircon corundum bricks, you can use a soft brush dipped in clean water to brush lightly. For stubborn stains, you can add a small amount of neutral detergent and avoid using strong acids and alkalis.

Q: What are the precautions when installing AZS zircon corundum bricks?
A: When installing AZS zircon corundum bricks, ensure that the bricks are dry, fill the masonry gaps with special refractory mud to avoid uneven force, and reserve space for thermal expansion.

Q: What is the difference between AZS zircon corundum bricks and ordinary corundum bricks?
A: AZS zirconium corundum bricks contain zircon, which is much more resistant to glass melt erosion than ordinary corundum bricks, and has better high temperature stability and mechanical strength.

Q: What should be paid attention to when transporting AZS zirconium corundum bricks?
A: When transporting AZS zirconium corundum bricks, they should be fixed with wooden boxes or pallets to avoid violent collisions and prevent the bricks from breaking. At the same time, they should be protected from rain and moisture.
