FAQ

Frequently Asked Questions


Q

Are white fused alumina bricks suitable for chemical equipment?


A

Yes! Its high-purity Al₂O₃ (≥99%) is resistant to acid and alkali corrosion and is suitable for use as a lining in chemical reactors and desulfurization and denitrification equipment.

Q

Which type of brick is the most erosion-resistant for glass furnaces?


A

Zirconia-corundum bricks are preferred for their excellent resistance to glass melt penetration and alkaline vapor, making them especially suitable for the tin bath and melting section of float glass production.

Q

Is technical guidance and installation advice provided?


A

Yes! Free selection suggestions, construction drawing review and on-site technical guidance are provided to ensure compliance with installation regulations.

Q

How long does it take to deliver a custom product?


A

Standard products are available in stock, and the production cycle for customized products is approximately 45-60 days (including mold development and quality inspection).

Q

What about the warranty period and after-sales service?


A

Provides a 1-3 year warranty (depending on product type), free repair or replacement of non-human damaged parts during the warranty period.

Q

Can your company's products be used in the new energy field (such as lithium battery sintering furnaces)?


A

Customizable corundum mullite bricks, high-temperature resistant (1600℃+), with good thermal shock resistance, suitable for negative electrode material sintering furnaces.

Q

Do the export products meet international standards?


A

The product is ISO 9001 certified, and some models meet ASTM and EN international standards, supporting export to Southeast Asia, the Middle East, and other regions.

Q

Is the price affected by fluctuations in raw materials?


A

Fluctuations in the prices of raw materials such as bauxite and silicon carbide may affect costs, but customers with long-term agreements can enjoy a price lock mechanism.

Q

What is the minimum order quantity (MOQ)?


A

Q

How can the thermal shock resistance of chrome corundum bricks be improved?


A

Chrome-alumina bricks are high-temperature refractory bricks commonly used in high-temperature kilns, electric furnaces, and molten metal equipment. Optimizing the formulation of chrome-alumina bricks can improve their thermal shock resistance, making them more durable and stable.
