In the high - temperature industrial furnace industry, fused AZS36 refractory bricks play a crucial role. This article will comprehensively analyze the core chemical composition and key physical properties of these bricks, and explain their outstanding application value in high - temperature industrial furnaces under the background of ISO international certification.

Chemical Composition of Fused AZS36 Refractory Bricks

Fused AZS36 refractory bricks mainly consist of several key chemical components. Alumina (Al₂O₃) accounts for about 36%, which is a major contributor to the high - temperature resistance of the bricks. Zirconia (ZrO₂) also occupies a significant proportion, usually around 30%. It enhances the corrosion resistance of the bricks at high temperatures. Silica (SiO₂) is another important component, around 25%. These chemical components work together to endow the bricks with excellent performance.

Physical Properties and Their Impact on High - Temperature Applications

Cold Crushing Strength

The cold crushing strength of fused AZS36 refractory bricks is an important indicator. Generally, it can reach over 400 MPa. Compared with ordinary refractory bricks, this high strength allows the bricks to withstand greater pressure during installation and use, reducing the risk of brick breakage and ensuring the long - term stability of the furnace lining.

High - Temperature Corrosion Resistance Rate

In high - temperature industrial environments, the corrosion resistance of refractory bricks is crucial. The high - temperature corrosion resistance rate of fused AZS36 refractory bricks is relatively low. Tests show that in a molten glass environment at 1500°C, the corrosion rate is less than 0.5 mm/year. This excellent corrosion resistance can significantly extend the service life of the furnace lining and reduce maintenance costs.

ISO International Certification and Quality Assurance

Fused AZS36 refractory bricks that meet ISO international standards have a reliable quality assurance mechanism. ISO certification ensures that the production process of the bricks is standardized and the quality is stable. For example, ISO 9001 certification guarantees the quality management system of the manufacturing process, while ISO 14001 certification reflects the environmental friendliness of the production process. These certifications provide strong backing for the performance and quality of the bricks.

Industry - Wide Performance Comparison

When compared with other similar refractory bricks in the industry, fused AZS36 refractory bricks show obvious advantages. In terms of cold crushing strength and high - temperature corrosion resistance, they are far superior to some traditional refractory materials. This comparison can help procurement personnel and technical managers make more scientific product selections.

By understanding the chemical composition, physical properties, and industry certification of fused AZS36 refractory bricks, procurement personnel and technical managers can build a professional understanding, improve their ability to select products, and control risks.
