Introduction to AZS Channel Bricks

In the high - temperature industrial environment, finding reliable refractory materials for high - temperature troughs has always been a challenge. AZS channel bricks emerge as a game - changer in this field. These bricks are made of fused alumina - zirconia - silica (AZS), a special refractory material designed specifically for high - temperature trough applications.

Material Characteristics of AZS Channel Bricks

The fused alumina - zirconia - silica material used in AZS channel bricks has unique properties. Alumina provides high hardness and excellent chemical stability, with a purity of up to 95%. Zirconia enhances the material's resistance to thermal shock, allowing it to withstand temperature changes of up to 1000°C without significant damage. Silica acts as a binder, ensuring the integrity of the material structure.

Compared with other refractory materials, such as ordinary clay bricks, AZS channel bricks have a much higher refractoriness. Ordinary clay bricks usually have a refractoriness of around 1500°C, while AZS channel bricks can withstand temperatures up to 1800°C. Additionally, AZS channel bricks have better corrosion resistance. In a corrosive environment with high - concentration molten glass, the corrosion rate of AZS channel bricks is only 1/3 of that of ordinary refractory bricks.

Manufacturing Process of AZS Channel Bricks

The manufacturing process of AZS channel bricks involves electric furnace melting, casting, and solidification to form a ceramic binder. First, high - purity raw materials are precisely proportioned and fed into an electric furnace. The electric furnace can heat the raw materials to over 2000°C, ensuring complete melting. The molten material is then cast into pre - designed molds. During the solidification process, strict temperature control is carried out to form a dense and uniform ceramic structure.

This manufacturing process ensures the high quality of AZS channel bricks. The density of the bricks can reach 3.8 - 4.0 g/cm³, which is much higher than that of ordinary refractory bricks. The high density provides better mechanical strength and wear resistance, extending the service life of the bricks in high - temperature troughs.

Quality Assurance and ISO Certification

The use of high - purity raw materials and scientific formulas is crucial for the quality of AZS channel bricks. Our company strictly selects raw materials with a purity of over 98% and formulates scientific formulas based on years of experience and research. This ensures that the bricks have stable performance and excellent quality.

Moreover, our AZS channel bricks have obtained ISO international certification. This certification is a symbol of our product's high - quality management system and reliable product quality. It provides global buyers with confidence in the quality and performance of our products.

Practical Application Cases

In a glass manufacturing plant in the United States, after using our AZS channel bricks in their high - temperature troughs, the maintenance cycle of the troughs has been extended from 6 months to 18 months. This not only reduces the maintenance cost but also improves the production efficiency. In a metal smelting plant in Germany, AZS channel bricks have effectively resisted the erosion of high - temperature molten metal, ensuring the stable operation of the smelting process.
