AZS bricks, also called fused cast zirconia corundum brick, are advanced refractory materials in high-temperature applications, particularly in the glass industry. As a professional manufacturer of AZS bricks, Kerui aims to provide customers with high-quality AZS bricks.
AZS bricks are named after the main components they consist of, which are alumina (Al2O3, zirconia (ZrO2), and silica (SiO2). In addition, they can withstand temperatures ranging from 1500°C (2730℉) to 1750°C (3182℉). AZS bricks have excellent performance in glass furnaces. Here are compositions of AZS refractory bricks:
Kerui Refractory produces AZS bricks applied in high-temp industries, especially in glass furnaces. Classified by zirconia content, Kerui AZS bricks have three grades: AZS-33, AZS-36 and AZS-41.

As a leading refractory bricks manufacturer in China, here are the steps of the automated production process of Kerui AZS brick:
Crown and Superstructure
The azs properties decided they are used in the crown and superstructure areas of glass furnaces. Meanwhile, these sections need to withstand high temperatures and corrosive conditions. Therefore, the high refractoriness and excellent resistance to glass corrosion make AZS refractory bricks ideal for these critical parts.
Throat and Working Side
The throat and working side of glass furnaces are under the heat environment and chemical attacks of molten glass. For example, refractory material suppliers AZS bricks in these areas can withstand harsh conditions, ensure durability and minimize refractory wear.
Channels and Spouts
Channels and spouts play an important role in directing the molten glass in glass furnaces. These areas use AZS bricks to maintain smooth glass flow, due to their exceptional corrosion resistance and longevity.
Bubblers and Refiner Blocks
Glass factories always use bubblers and refiner blocks for glass refining processes. So they require refractory materials with high resistance to alkali vapor attack and erosion. AZS bricks offer the necessary durability and resistance to chemical corrosion in these applications.
Bottom Paving
The Bottom paving areas of glass furnaces are under extreme conditions, which include high temperatures and corrosion. In these critical sections, AZS refractory bricks can ensure structural integrity. Meanwhile, it can extend the service life of the furnace.
The Common ceramic fiber blankets include alumina-silica fibers, Kerui AZS bricks have stable quality. For instance, Kerui manufactures AZS bricks by using high-quality raw materials and advanced production techniques, which ensures uniformity in composition and performance. Thus, this stability in quality guarantees reliable results in glass kilns.
Kerui implements strict quality control measures throughout the production process. Meanwhile, Kerui will conduct a thorough inspection of the physical and chemical properties of each batch of AZS bricks in a professional laboratory to ensure that the refractory bricks meet customer requirements. Therefore, the refractory bricks supplied by Kerui have a long service life.
In addition to high quality and performance, Kerui offers customers competitive AZS refractory bricks price. This competitive pricing makes Kerui AZS bricks a better choice for glass manufacturers. As a source manufacturer, it can provide the factory direct selling price.
AZS refractory bricks from Kerui Refractory are known for their long service life. In particular, they have excellent resistance to thermal shock, corrosion, and erosion. Meanwhile, this durability means longer intervals between maintenance and replacement, to reduce downtime and the total cost of glass kiln operation.
