SOLUTIONS FOR GLASS APPLICATIONS Process Optimization Through Precise Control and Non-Contact Temperature Measurement Temperature measurement and control is key to the monitoring and optimization of energy-intensive glass production processes. Careful temperature monitoring during glass production is the only way to ensure product quality meets stringent marketplace requirements. While temperature control has an impact on the actual quality and reliability of the finished glass, it all comes together when the individual coating layers are added. Temperatures during various production stages...

SOLUTIONS FOR GLASS APPLICATIONS Emissivity of Glass in the Infrared Spectrum Important optical properties of flat glass transmission (τ), reflection (ρ), and emissivity (ε) (or absorption (α)) affect the performance in many common applications. The high energy UV portion of the solar spectrum (wavelength less than 400 nm) can be damaging to many materials including human skin. Since the transmission of glass is relatively low in this region, thick glass can be an effective UV block. Visual light (400 to 750 nm) easily passes through glass since the transmission is very high in this region....

SOLUTIONS FOR GLASS APPLICATIONS Glass Melting Regenerator Protecting the expensive regenerator crown refractory is important in the glass melting process. Typical thermocouples deteriorate over time and can be unreliable, but infrared pyrometers measure temperature without contact and remain outside high-temperature zones, providing long-term reliability. This enables operators to maintain efficient and stable operation of the melting tank at higher temperatures. SCR power controllers monitor and control the power of each zone precisely throughout the process. Melting Tank Sand, limestone,...

SOLUTIONS FOR GLASS APPLICATIONS 01 Flat Glass Tin Bath The tin bath is the key component in the modern float glass process. Molten glass from the melting tank enters the tin bath through a canal and floats on top of the molten tin. Near the entrance of the controlled chamber, temperature is kept high to allow the molten glass to spread and smooth out. The glass is then allowed to cool in the various heating/cooling zones. Ensuring proper temperature of these cooling zones is essential to maintaining uniformity. Annealing Lehr After the glass ribbon is properly formed, it is moved through...
