Introduction of fused cast AZS 36#doghouse corner blocks:
Glass furnace doghouse corner blocks are located at the corner of the doghouse of the glass furnace, which is the key channel for the glass raw materials to enter the glass furnace. Due to the corner position, the corner block not only has to withstand the pressure and impact from the glass raw materials, but also has to withstand the high temperature and high pressure environment inside the glass furnace, so the stress situation is more complicated.
Structural characteristics:
Doghouse corner blocks need to be sized to precisely match the corners of the glass furnace‘s doghouse corner to ensure that they fit tightly and withstand the pressures and impacts from all sides. Due to their corner location, corner blocks often have special shapes and require special manufacturing processes.
Advantages of choosing fused cast AZS blocks:
High refractoriness:
Fused cast AZS blocks have an extremely high refractoriness, capable of reaching over 1790°C. With the extremely high temperatures inside glass furnaces, doghouse corner blocks need to have good high temperature stability to maintain long-term stability of shape and performance.
High load softening temperature:
Fused cast AZS blocks have low impurity mass, and the load softening temperature of Al-Zr products can be above 1550~1650℃. This means that under high temperature and heavy pressure, fused cast AZS blocks can still maintain good shape stability and mechanical strength, and are not easy to soften or deform.
Good Thermal Shock Resistance:
Glass furnaces experience drastic temperature changes during operation. If the doghouse corner blocks do not have sufficient thermal shock resistance, they are prone to cracking due to the temperature changes. Fused cast AZS blocks have good thermal shock resistance and can withstand such drastic temperature changes without cracking or damage.
Excellent chemical erosion resistance:
Due to direct contact with glass raw materials and glass liquids, doghouse corner blocks need to be extremely erosion-resistant in order to prevent being damaged by erosion. Fused cast AZS blocks are highly resistant to the erosion of glass melts and gaseous agents, and have excellent resistance to chemical attack.
Various casting methods to meet the demand:
Fused cast AZS refractory blocks can be cast in various ways, such as regular casting, tilt casting, void-free casting and end casting. This can meet the special requirements of doghouse corner blocks for glass furnace.
