Have you ever wondered how dense zirconium blocks play a core role in glass furnaces? This article will comprehensively unveil the outstanding performance of dense zirconium blocks, elucidate their specific applications in different types of glass furnaces, and analyze how they solve customers' pain points in glass production.

Exceptional Properties of Dense Zirconium Blocks

Dense zirconium blocks possess a series of remarkable properties that endow them with unparalleled advantages in the glass furnace industry.

• Crystal Structure Density: Their crystal structure is highly compact, which provides a stable foundation for other excellent properties. This density can effectively prevent the intrusion of molten glass and other substances, significantly enhancing the durability of the lining material in the furnace.
• High-Temperature Resistance: Dense zirconium blocks can withstand extremely high temperatures. They can maintain structural stability and performance even at 1600°C, ensuring normal operation under high-temperature conditions in glass furnaces.
• High Mechanical Strength: With a compressive strength of up to 400 MPa, these blocks can withstand the mechanical stress generated during the operation of glass furnaces, such as expansion and contraction caused by temperature changes and impacts during material loading.
• Good Wear Resistance: In the harsh environment of glass furnaces, the inner lining materials are often subject to friction and erosion from materials. Dense zirconium blocks, with an abrasion rate of less than 0.5 cm³/hm, have excellent wear resistance, effectively prolonging the service life of the furnace lining.

Specific Applications in Different Glass Furnaces

Alkali-Free Glass Fiber Furnaces

Alkali-free glass fiber production requires extremely high furnace material performance. The corrosion resistance and high-temperature stability of dense zirconium blocks can effectively prevent the reaction between the furnace lining and the molten glass, ensuring the purity and quality of the glass fiber. For example, a glass fiber manufacturer replaced the original furnace lining with dense zirconium blocks and increased the product quality rate from 85% to 95%.

Low-Alkali Borosilicate Glass Furnaces

Low-alkali borosilicate glass has high requirements for uniformity and thermal stability. Dense zirconium blocks can maintain stable performance at high temperatures, providing a stable thermal environment for glass melting and ensuring the uniform distribution of temperature in the furnace. In a glass factory, after using dense zirconium blocks, the thermal efficiency of the low-alkali borosilicate glass furnace increased by 15%, and the production cycle was shortened by 20%.

Solving Customers' Pain Points in Glass Production

During the glass production process, customers often face several pain points, such as poor product quality, short furnace service life, and high production energy consumption. Dense zirconium blocks offer effective solutions:

• Improving Product Quality: The excellent chemical stability and high-temperature resistance of dense zirconium blocks prevent the pollution of the molten glass by the lining material, thereby improving the purity and quality uniformity of the glass products.
• Prolonging Furnace Service Life: Thanks to their high mechanical strength and wear resistance, dense zirconium blocks can withstand long-term mechanical and chemical erosion, significantly reducing the frequency of furnace repairs and replacements and lowering maintenance costs.
• Reducing Production Energy Consumption: Dense zirconium blocks have good thermal insulation properties, which reduce heat loss during glass melting and improve thermal efficiency, thus reducing energy consumption during the production process.
