Glass kilns are subjected to high-temperature erosion and chemical corrosion for a long time, so the choice of lining material directly affects the kiln’s lifespan and production efficiency. Zirconium corundum refractory bricks have become a key material in the glass industry due to their excellent high-temperature resistance and corrosion resistance.
1. Characteristics and advantages of zirconia-corundum refractory bricks
Zirconium corundum bricks, also known as alumina-zirconia-silica (AZS) refractory bricks.It is an ideal choice for glass furnaces, especially for the upper structure of the melting section and the pool walls.
First, it has excellent resistance to molten glass corrosion. This directly extends the operating cycle of the kiln.
Secondly, it has a lower tendency to leach gas. This reduces contamination of the molten glass, thus ensuring the high quality of glass products.
Various zirconium refractory fire bricks
Compared to traditional silica bricks or ordinary high-alumina bricks, zirconia-corundum refractory bricks have significant advantages in terms of erosion resistance and service life.
Therefore, it is particularly suitable for use in key parts of glass kilns.
2. Key application parts in glass furnaces
In glass furnaces, the requirements for refractory materials vary significantly in different areas. Therefore, it is necessary to select brick types specifically.
Since the walls and bottom of the melting tank are in long-term contact with the high-temperature molten glass, it is necessary to use materials with strong corrosion resistance, such as zirconia-corundum refractory bricks. The feed port area must withstand both mechanical impact and chemical corrosion. Therefore, this type of brick is also suitable.
Although the temperature in the upper part of the kiln is relatively low, a more reasonable refractory material configuration system can be formed if high-quality silica bricks or mullite bricks are used.
This layered material selection strategy not only ensures the overall performance of the kiln, but also helps to optimize the price and cost of refractory bricks.
3. Choose a reliable refractory brick supplier
There are many refractory brick manufacturers on the market, so it is necessary to comprehensively evaluate many factors when purchasing.
In addition to the price of refractory bricks, more attention should be paid to the supplier’s production qualifications, quality control system, and technical support capabilities.
High-quality refractory brick suppliers not only provide products that meet standards, but also offer masonry guidance and after-sales follow-up services.
