What is AZS Refractory Brick?
- “A” of AZS brick is Alumina (Al2O3). Alumina of AZS brick is extremely high and reaches at least 90%. As we all know, higher content of Al2O3 commonly refers to higher refractoriness and density.
- “Z” of AZS brick is Zirconia (ZrO2). Zirconia has better resistance to glass solution erosion. Moreover, it can also reduce the risk of cracking and cracking of bricks due to thermal expansion at high temperatures.
- “S” of AZS brick is Silica (SiO2). Silica forms a dense glass phase in AZS bricks, which can prevent the penetration of glass melt and prevent the melt from eroding the AZS brick.
In addition to the chemical compositions mentioned above, Kerui AZS refractory brick also contains Fe2O3, CaO, MgO, Na2O and many other small amounts of chemical elements. Other names about Kerui AZS brick are fused cast brick, alumina zirconia silica brick, zirconia corundum brick, fused Zirconia corundum brick and so on. Besides, this kind of firebrick for sale has better heat resistance features and higher density, so customers often use AZS brick in working environments with higher standards.

Advanced Manufacturing Process of Kerui Fused Cast AZS Brick
The quality of AZS brick is influenced by proportions of AZS heating and cooling process during production. Kerui adopts highly intelligent manufacturing process for the fused cast azs block. Here are details about the process:
Kerui selects alumina, zirconia and other materials with high purity to manufacture AZS bricks. Moreover, the fully automatic batching system makes it available to get AZS bricks with pure texture and reasonable crystal phase structure.
There is a full set of advanced melting equipment here. It is worth mentioning that the efficient cooperation between the control system and the oxygen blowing equipment ensures the uniformity and stability of the product quality.
The molten liquid is cast into molds. In this step, Kerui provides CAD, CAXD and 3D design services to efficiently meet customer needs. In addition, production of fused cast alumina block uses an integrated model structure to improve the surface flatness.
In the cooling stage of AZS bricks, Kerui adopts unique annealing technology, so that AZS bricks cool down at a reasonable rate and reduce cracks. In addition, Kerui uses a high-precision equipment enhances the appearance of the AZS refractories.
Importantly, Kerui adopts advanced radar detection equipment, which can effectively detect the interior of AZS fire bricks. In addition, the intelligent image detection system provides high-quality supervision services.
During the delivery stage, Kerui employees package in strict accordance with the work instructions and packaging label requirements. According to the contract, Kerui provides timely and safe delivery service for each customer.
Excellent Performance of Kerui AZS Brick
The refractoriness of Kerui AZS brick and other fused cast refractories reaches 3092℉ (1700℃), which is far more than other refractory bricks. High refractoriness can maintain the structural integrity and mechanical properties at extremely high temperatures.
AZS bricks have good chemical stability and strong resistance to slag, especially in glass solution. Besides, the combination of alumina and zirconia helps prevent some negative reactions. Thus it’s suitable for cusatomers to purchase Kerui fused cast refractories to reduce corrosion and erosion.
No matter in the production process or application process, Kerui has strict control over environmental conservation. Additionally, this is the reason why worldwide customers purchase wholesale AZS brick from Kerui Refractory.
There is Zirconia in AZS brick, which enhances its anti-strip performance. This brick is helpful to avoid attacking to the glass furnace lining. Application of this brick can effectively improve the longevity of the high-temperature furnace lining.
Wide Applications of Kerui AZS Refractory Brick
Mainly Use in Different Parts of Glass Kilns
AZS bricks are widely used in the glass industry due to their excellent properties and suitability for glass melting processes. Customers commonly use superior AZS brick at upper structures, side walls of refiners, linings, paving blocks, fore-hearth channel blocks and other key parts of glass kilns.
Also Use in Other High-temperature Industries
Moreover, Kerui AZS refractory brick is appropriate for high temperature kilns with severe chemical erosion and frequent temperature changes. For example, steel ladle lining, incinerators, sodium silicate furnaces, ceramic frit furnaces, foundry plants and so on. You can also follow Kerui Facebook to know more information.
