In the glass industry, the choice of refractory materials is crucial for ensuring efficient production and prolonging the service life of equipment. Among various refractory materials, zirconia-mullite bricks have emerged as a popular choice for many glass factories. This article will comprehensively introduce zirconia-mullite bricks, aiming to help glass industry procurement and technical decision-makers make informed choices.
Zirconia-mullite bricks are made from high-quality raw materials, including zircon sand, bauxite, and other additives. These raw materials are carefully selected to ensure the high purity and high density of the final product. The high-temperature sintering process is another key factor in the production of zirconia-mullite bricks. During the sintering process, the raw materials are heated to a very high temperature, usually above 1700°C. This high-temperature treatment not only enhances the physical and chemical properties of the bricks but also improves their thermal shock resistance and anti-stripping performance.
One of the most remarkable features of zirconia-mullite bricks is their excellent thermal shock stability. In the glass production process, the temperature of the furnace often changes rapidly. Zirconia-mullite bricks can withstand these rapid temperature changes without cracking or spalling. According to research, zirconia-mullite bricks can maintain their structural integrity after experiencing more than 100 thermal shock cycles, which is much higher than many other refractory materials.
Zirconia-mullite bricks also have excellent anti-stripping and anti-corrosion performance. The high density and high purity of these bricks make them highly resistant to the erosion of molten glass. In a long-term production environment, zirconia-mullite bricks can effectively prevent the penetration of molten glass, thereby protecting the furnace lining and extending the service life of the equipment. Studies have shown that the corrosion rate of zirconia-mullite bricks in contact with molten glass is only about 1/3 of that of ordinary refractory bricks.
To better illustrate the application effects of zirconia-mullite bricks, let's take a look at a real industry case. A large glass factory in Europe was facing problems such as frequent furnace lining repairs and low production efficiency due to the use of ordinary refractory materials. After replacing the refractory materials with zirconia-mullite bricks, the situation was significantly improved. The production efficiency of the glass factory increased by about 20%, and the maintenance cycle of the furnace lining was extended from 6 months to 18 months. This not only reduced the production cost but also improved the overall competitiveness of the enterprise.
In conclusion, zirconia-mullite bricks, with their outstanding thermal shock stability, anti-stripping and anti-corrosion performance, are an ideal choice for the glass industry. Whether you are looking to improve production efficiency, extend the service life of equipment, or reduce production costs, zirconia-mullite bricks can meet your needs.
