Product Introduction
Fused Brick AZS37-Y is a specific model of fused zirconia corundum brick (AZS fused brick). Here are some details about it:
1. Ingredients:
Alumina (Al₂O₃): It plays a role in improving refractoriness, increasing high-temperature strength and erosion resistance in this type of brick. Although the specific alumina content is not clearly reflected in the model, the alumina content of fused brick AZS37 as a whole is in a specific range, which has an important impact on the performance of the brick.
Zirconia (ZrO₂): It is one of the key components of fused zirconium corundum bricks, which has a high melting point and chemical stability, and can effectively resist the erosion of high-temperature melts such as molten glass. In the case of AZS37-Y, the zirconia content may be close to or slightly higher than 37%, making it more resistant to erosion.
Silica (SiO₂): As the main component of the glass phase, it plays a role in bonding and filling in the brick body, helping to form the overall structure of the brick, but too much silica may reduce the refractory and erosion resistance of the brick.
2. Performance characteristics:
High refractoriness: It can withstand high-temperature environment, can be used for a long time in high-temperature industrial kilns such as glass kilns without softening, deformation or damage, and is suitable for use in high-temperature parts.
Good erosion resistance: It has strong resistance to high-temperature melts such as molten glass and slag, and is not easy to be eroded, which can maintain the structural integrity and dimensional stability of bricks, thereby prolonging the service life of the kiln.
High mechanical strength: It has high compressive strength, bending strength and other mechanical properties, can withstand various stresses and loads inside the kiln, and is not easy to break or damage.
Good stability: It has good volume stability at high temperature, low coefficient of thermal expansion, and will not produce excessive volume expansion or contraction due to temperature changes, which reduces the problems of brick cracking caused by thermal stress.
3. Usage:
Glass kiln: It is the main application field of fused brick AZS37-Y, which can be used to build key parts such as pool wall, ballast roof, and breast wall of masonry glass kiln, and can withstand the high temperature erosion and erosion of molten glass.
Other high-temperature industrial kilns: In some high-temperature industrial kilns with high requirements for refractory materials, such as metallurgical furnaces, aluminum smelting furnaces, etc., fused brick AZS37-Y can also be used as the lining material to improve the service life and production efficiency of the kiln.
4. Quality grade: The "Y" in the model represents the first-class product, which means that the fused brick has reached a high standard in terms of physical and chemical properties, dimensional deviation and appearance quality, and can meet the requirements of high-quality engineering.
In conclusion, fused brick AZS37-Y is a refractory with excellent performance and has a wide application prospect in high-temperature industrial kilns. When using, it is necessary to choose the appropriate fused brick model and masonry method according to the specific kiln type, use site and process requirements and other factors to ensure the normal operation and service life of the kiln.
