In the glass production industry, the contamination of molten glass has long been a pressing issue. Impurities in the molten glass can lead to defects in the final glass products, such as bubbles, streaks, and reduced transparency, which ultimately affect the quality and market competitiveness of the products. This is where the electro - fused α - alumina block TY - A comes into play.
The electro - fused α - alumina block TY - A is made from high - purity alumina. The Al₂O₃ content in the raw material is over 98%, which is a remarkable figure. This high purity means that there are extremely few impurities in the block. In contrast, traditional refractory materials may contain a significant amount of impurities, which can easily dissolve into the molten glass during the production process. For example, impurities like iron oxide can cause color changes in the glass, while other metal oxides can form bubbles or inclusions.
Let's take a look at some data. In a series of laboratory tests, when using traditional refractory materials, the impurity content in the molten glass increased by about 0.5% after 10 hours of continuous contact. However, when using the electro - fused α - alumina block TY - A, the impurity content only increased by 0.05% under the same conditions. This significant difference clearly shows how the high - purity characteristic of TY - A can effectively reduce the pollution of the molten glass.
The electro - fused α - alumina block TY - A is produced through a melting and casting process in an electric furnace at 2000℃. This high - temperature process allows the raw materials to melt completely and then form a dense structure during the casting process. The dense structure gives the block strong resistance to alkaline substances and excellent high - temperature corrosion resistance.
In glass production, the molten glass often contains alkaline components, such as sodium carbonate. Traditional refractory materials may be corroded by these alkaline substances over time, which not only shortens the service life of the refractory materials but also increases the risk of glass contamination. The electro - fused α - alumina block TY - A, with its strong alkaline resistance, can maintain its integrity and stability in such a harsh environment. In terms of high - temperature corrosion resistance, it can withstand the high - temperature environment of up to 1600℃ in the glass furnace, ensuring long - term and stable operation of the furnace.
Many glass production enterprises have already benefited from using the electro - fused α - alumina block TY - A. For example, a medium - sized glass production company used to have a defect rate of about 8% in its glass products due to molten glass contamination. After replacing the traditional refractory materials with the electro - fused α - alumina block TY - A, the defect rate dropped to 2% within three months. At the same time, the service life of the furnace lining was extended from 12 months to 18 months, which significantly reduced the production cost and improved the production efficiency.

Defect Rate | 8% | 2% |
Furnace Lining Service Life | 12 months | 18 months |
The electro - fused α - alumina block TY - A, with its high - purity raw materials, advanced production process, and proven performance in real - world applications, is an ideal refractory material for glass production. It can effectively reduce the pollution of molten glass, improve the quality of glass products, and extend the service life of the furnace lining.
We strongly encourage glass production enterprises to try using the electro - fused α - alumina block TY - A. By doing so, you can enhance the quality of your products, reduce production costs, and ultimately improve your competitiveness in the market. Don't miss this opportunity to take your glass production to the next level!
