You may have encountered issues with critical parts of glass furnaces failing prematurely. These failures not only lead to increased maintenance costs but also cause significant downtime, affecting your production efficiency. This is where fused AZS cast blocks come into play. They are essential for enhancing the performance and longevity of glass furnaces.
Fused AZS cast blocks are composed of high - purity Al2O3 - ZrO2 - SiO2. The specific ratio of these three components is crucial for their performance. For example, a well - balanced ratio can form a dense microstructure. As shown in the figure below (
), the dense structure of AZS cast blocks is quite different from ordinary materials. This structure gives AZS cast blocks excellent wear - resistance, thermal shock resistance, and corrosion resistance. An industry expert once said, "The unique structure of AZS cast blocks makes them a top - choice material for high - temperature and corrosive environments in glass furnaces."
Let's look at how AZS cast blocks perform in different areas of glass furnaces:
In the upper structure of the glass furnace, AZS cast blocks can withstand high - temperature flue gases and thermal radiation. They prevent the upper structure from being eroded, reducing the need for frequent repairs and thus decreasing downtime.
The sidewalls are in direct contact with the molten glass. The corrosion - resistant property of AZS cast blocks ensures that the sidewalls remain intact, which helps in maintaining the shape and stability of the furnace, ultimately extending the equipment's life.
Charging channels experience wear from the continuous flow of raw materials. AZS cast blocks' wear - resistance can effectively reduce the wear and tear in this area, lowering maintenance costs.
During the installation of AZS cast blocks, there are some common mistakes that you need to avoid:
| Common Mistakes | Solutions |
|---|---|
| Improper brick joint treatment | Use high - quality refractory mortar and ensure uniform joint thickness. The joint width should be controlled within 1 - 2mm. |
| Insufficient thermal expansion allowance | Calculate the expansion amount according to the temperature range of the furnace and leave appropriate expansion joints. Generally, an expansion joint of 3 - 5mm per meter of block length is recommended. |
Regular maintenance is key to extending the service life of AZS cast blocks. You should conduct regular inspections to check for any signs of wear, cracks, or corrosion. Cleaning the surface of the blocks can prevent the accumulation of impurities, which may accelerate corrosion. Additionally, controlling the furnace temperature within a reasonable range can avoid excessive thermal stress on the blocks. Studies have shown that proper maintenance can extend the service life of AZS cast blocks by up to 30%.
One of our clients reported that after using AZS cast blocks in their glass furnace and following our installation and maintenance guidelines, they reduced their annual maintenance costs by 20% and extended the furnace's service life by 2 years. This real - world example demonstrates the effectiveness of AZS cast blocks and proper installation and maintenance.
