In the global glass manufacturing industry, the challenges faced by glass kilns have always been a headache for manufacturers. Issues such as high - temperature corrosion, wear, and short service life of kiln materials can lead to increased production costs and reduced product quality. But don't worry! If you miss this, you'll lose the solution to glass production problems. Here, we introduce you to the dense zirconium block, a revolutionary material that can effectively address these pain points.

Unveiling the Dense Zirconium Block

The dense zirconium block is a high - performance refractory material with a series of outstanding characteristics:

• Crystal Structure Denseness: Its crystal structure is extremely dense, with a porosity of less than 5%. This means it has excellent resistance to gas and liquid penetration. In comparison, traditional refractory materials may have a porosity of around 15 - 20%, making them more vulnerable to the intrusion of corrosive substances.
• High Strength: The dense zirconium block has a compressive strength of up to 500 MPa. This high strength allows it to withstand the mechanical stress and impact in the kiln environment, ensuring the structural integrity of the kiln.
• Wear Resistance: Thanks to its hard and dense structure, it has excellent wear resistance. In a glass kiln, the wear rate of the dense zirconium block is only about 1/3 of that of ordinary refractory materials, greatly extending its service life.
• High - Temperature Resistance: It can maintain its stable physical and chemical properties at temperatures up to 1800°C, making it suitable for the high - temperature environment of glass melting.

Applications in Glass Kilns

The dense zirconium block is the ideal material for key parts of alkali - free glass fiber kilns and low - alkali borosilicate glass kilns. Let's take a look at its specific application scenarios:

In alkali - free glass fiber kilns, the dense zirconium block is used in the melting area and the feeder channel. For example, in a large - scale alkali - free glass fiber kiln in a European factory, after replacing the traditional refractory materials with dense zirconium blocks in the melting area, the service life of the kiln was extended from 2 years to 5 years, and the glass fiber production efficiency increased by 20% due to the more stable melting environment.

In low - alkali borosilicate glass kilns, it is mainly used in the throat and the forehearth. A glass factory in Asia reported that after using dense zirconium blocks in the throat, the quality of the glass products improved significantly, and the rejection rate decreased from 8% to 2%.

Solutions to Potential Problems in Glass Production

There are several potential problems in glass production, such as glass contamination caused by the erosion of refractory materials, uneven melting due to poor heat transfer, and short kiln service life. The dense zirconium block can effectively solve these problems:

• Preventing Glass Contamination: Its chemical stability prevents it from reacting with the molten glass, thus avoiding the contamination of the glass by impurities from the refractory materials.
• Ensuring Uniform Melting: The high thermal conductivity of the dense zirconium block helps to achieve uniform heat distribution in the kiln, ensuring the uniform melting of the glass raw materials.
• Extending Kiln Service Life: As mentioned above, its excellent wear resistance and high - temperature resistance can significantly extend the service life of the kiln, reducing the frequency of kiln repairs and replacements.
