- Apparent Porosity (%) :18 – 20
Detailed Description of AZS Brick
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:
Alumina
Alumina is the main component of AZS bricks and usually contains about 50-70%. At the same time, it has high refractoriness and thermal stability and can withstand extremely high temperatures.
Zirconia
Zirconia is typically present in AZS bricks about 25-40%. Besides, the addition of it helps to improve thermal shock resistance. So it plays a crucial role in the bricks due to its properties.
Silica
Silica is usually around 5-10% in AZS bricks, which provides additional refractory properties. For example, silica helps to maintain the integrity of the brick in high-temperature environments.
Different Grades of Kerui AZS Brick
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.

|---|---|---|---|
| SiO2, % | 12 | 13 | 15 |
| Al2O3, % | The Remainder | The Remainder | The Remainder |
| ZrO2, % | 41 | 36.5 | 33.5 |
| Bulk Density, g/cm3 | 4.05 | 3.9 | 3.8 |
| Apparent Porosity, % | 0.6 | 0.8 | 0.7 |
| Initial Precipitation Temperature of Vitreous Phase, ℃ | 1400 | 1400 | 1400 |
| Vitreous Phase Exudation, % (1500℃*4h) | 1.5 | 2.3 | 2 |
| Anti-molten Glass Erosion Speed Under Static Condition, mm/24h (1500℃*36h, ordinary soda lime glass) | 1.2 | 1.3 | 1.4 |
| Bubble Release Rate, % (1300℃*10h, ordinary soda lime glass) | 0.6 | 1 | 1.2 |
Automated Production Process of Kerui AZS Brick
As a leading refractory bricks manufacturer in China, here are the steps of the automated production process of Kerui AZS brick:
The first step is to obtain the necessary raw materials, including alumina, zirconia and silica. In addition, these materials are carefully selected based on their purity and quality to ensure the desired properties of the AZS brick.
Then, Kerui company uses advanced melting equipment for producing AZS refractory bricks. At the same time, with the help of intelligent control system, the AZS bricks from Kerui will have the table quality.
Next, the molten raw material is cast into a mold. Using integrated model structure can improve the surface quality of bricks. Meanwhile, unique CAD, CAXD, and 3D design can efficiently select the best design solution.
Heating and cooling of AZS bricks refer to the gradual cooling of the kiln after the AZS brick heating and firing process is complete. Besides, special annealing insulation technology ensures that the bricks cool down at a reasonable rate.
Kerui refractory manufacturer implement quality control measures to ensure that the bricks meet the required standards. Therefore, the appearance, shrinkage cavity, size, precision and weight of Kerui’s bricks can meet your needs.
The final step includes packaging the Kerui refractory bricks for shipping and distribution to customers or end users. At the same time, the bricks are generally carefully packaged to prevent damage during handling and transportation.
