In the high - temperature industrial landscape, fused AZS36 refractory bricks stand as a cornerstone for applications such as glass melting furnaces. But what truly sets them apart and ensures their reliability? The answer lies in the ISO certification, a global standard that provides a scientific and rigorous framework for quality control.
Fused AZS36 refractory bricks are engineered with a unique chemical composition. With Al₂O₃ content of at least 49% and ZrO₂ content of at least 35.5%, these bricks possess inherent stability. Physically, they have a bulk density of no less than 3.85g/cm³ and an apparent porosity of no more than 1%. To put it in perspective, if we compare the apparent porosity to the pore density of human skin, a lower porosity in the bricks means better resistance to external intrusion, just like healthy skin with fewer pores is less prone to dirt and bacteria.
However, in high - temperature industrial applications, such as glass melting furnaces, ordinary AZS bricks often face issues like rapid corrosion. This is where the core technical advantages of fused AZS36 come into play. The high - temperature corrosion resistance rate of fused AZS36 is no more than 1.3mm/24h, significantly lower than that of ordinary AZS bricks. This makes it an ideal choice for glass melting furnace linings, where long - term stability is crucial.
The ISO certification system provides a comprehensive and strict quality control mechanism for fused AZS36 refractory bricks. From raw material sourcing to the final product, every step is monitored according to ISO standards.
ISO standards mandate strict control over factors such as raw material purity, production process parameters, and product testing procedures.This ensures that each brick meets the required performance criteria.
For example, during the production process, the temperature and pressure are precisely controlled to ensure the proper formation of the brick's internal structure. After production, a series of tests are carried out, including chemical composition analysis, physical property testing, and performance evaluation under simulated actual working conditions.
Let's break down the practical significance of some key performance indicators. The cold crushing strength of fused AZS36 is at least 300MPa. In a glass melting furnace, the bricks are subject to various mechanical stresses. A high cold crushing strength ensures that the bricks can withstand these stresses without cracking or deforming, maintaining the integrity of the furnace lining.
The glass phase precipitation temperature of at least 1400°C is also of great importance. At high temperatures, the glass phase in the bricks can affect their performance. A higher glass phase precipitation temperature means that the bricks can maintain their stable structure at higher temperatures, reducing the risk of structural failure in high - temperature environments.
When comparing fused AZS36 with ordinary AZS bricks, the data clearly shows its superiority. In terms of corrosion rate, ordinary AZS bricks may corrode at a rate of 3 - 5mm/24h, while fused AZS36 has a corrosion rate of no more than 1.3mm/24h. This significant difference in corrosion rate means that fused AZS36 can last much longer in high - temperature and corrosive environments, reducing the frequency of furnace lining replacement and saving costs for enterprises.
Consider a scenario where the side wall of a glass melting furnace fails. In many cases, this is due to the rapid corrosion of the furnace lining bricks. If ordinary AZS bricks are used, the high corrosion rate may lead to side wall damage within a relatively short period, causing production interruptions and increased maintenance costs. However, when using fused AZS36 refractory bricks, the low corrosion rate ensures the long - term stability of the side wall, reducing the risk of such failures.
Globally, more than 80 glass factories have chosen fused AZS36 refractory bricks for their glass melting furnaces. This widespread adoption is a testament to the reliability and quality of the product under the ISO certification system.
In conclusion, the ISO certification for fused AZS36 refractory bricks is not just a compliance endorsement but a scientific verification of reliability. If you are looking for high - quality refractory materials for your high - temperature industrial applications, don't miss out on the opportunity to explore the benefits of fused AZS36.
