Application fields of AZS bricks

Glass industry

In the field of glass manufacturing, AZS bricks are the key materials for tank kilns. The bottom, wall, upper structure and feed channel of the glass kiln are eroded and corroded by high-temperature glass liquid for a long time. With its excellent high temperature and corrosion resistance, AZS bricks can effectively resist these erosions, ensure the normal operation of high-temperature kilns, and thus improve glass quality and production efficiency. For example, in float glass production, AZS bricks are widely used in key parts of tank kilns, providing a stable foundation for the continuous production of glass. Different types of AZS bricks have different application scenarios in glass kilns. AZS-33 is mainly used for relatively low temperature and less corrosive working ends, supply channels and other parts; AZS-36 is suitable for parts with high corrosion resistance and temperature requirements, such as side walls, pavements, etc.; AZS-41 is especially suitable for parts with severe corrosion in glass melting furnaces, such as the bottom, dam blocks, corners, etc., and can also be used in side walls.

Metallurgical industry

In the metallurgical industry, AZS bricks are often used to build the lining of degassing ladle, stainless steel ladle, rolling ladle, etc. During the steel smelting process, the ladle needs to withstand the erosion of high-temperature molten steel and the wear of slag. The excellent wear resistance and corrosion resistance of AZS bricks can effectively reduce the wear of the furnace slag in the ladle on the furnace wall and the erosion of molten steel, thereby extending the service life of the ladle. This not only reduces production costs, but also improves production safety and stability.

Ceramic industry

During the ceramic firing process, the ceramic firing furnace needs to operate stably for a long time under high temperature environment. AZS bricks can be used in the key parts of the ceramic firing furnace to resist high temperature erosion and provide a stable working environment for ceramic firing. It can withstand temperature changes and chemical erosion during high-temperature firing to ensure the quality and firing effect of ceramic products.

Advantages of AZS Bricks

High Refractoriness

AZS bricks have a refractory temperature of over 1790℃, and are classified as advanced refractory materials. This allows it to maintain stable physical and chemical properties for a long time in high-temperature industrial environments, and will not soften, deform or melt due to high temperatures.

High load softening temperature

Its load softening temperature is generally above 1550-1650℃. This means that under a certain weight, AZS bricks can still maintain good shape and structural stability in a high-temperature environment, and will not easily deform or collapse. In glass kilns, AZS bricks need to bear the weight of high-temperature glass liquid, and the high load softening temperature ensures that it can do this job.

Good thermal shock resistance

In industrial production, kilns often experience temperature changes such as heating and cooling. AZS bricks have good thermal shock resistance and can withstand rapid changes in temperature without cracking or damage. During the opening and closing of the glass furnace, the temperature changes greatly. The thermal shock resistance of AZS bricks ensures its reliability in these processes.

Excellent chemical corrosion resistance

AZS bricks have good resistance to acidic or alkaline slag, molten metal corrosion, oxidation and reduction reactions, and with the increase of AL₂O₃ content and the decrease of harmful impurities, its chemical corrosion resistance will be further enhanced. In the metallurgical industry, slag and molten steel are highly corrosive. The chemical corrosion resistance of AZS bricks enables them to be used for a long time in such harsh environments. Although AZS bricks have many advantages, their unit price is relatively high. Therefore, when choosing to use them, it is necessary to comprehensively consider the overall situation of the kiln and the budget, and seek ways to reduce costs and increase efficiency while ensuring the stability of the kiln. With the continuous advancement of science and technology, it is believed that the performance of AZS bricks will continue to improve in the future, and the application field will be further expanded.
