Flat glass is used for a variety of applications, including architectural and automotive glass. Precision measurements of temperature and uniformity of cooling are important for a high-quality end product.
AMETEK Land offers an extensive range of highly accurate instruments to provide the thermal measurements and data required for efficiency and product quality. We have supplied the glass industry with flat glass solutions for decades, developing dedicated solutions for specific applications within the process.
APPLICATION NOTE
TEMPERATURE MEASUREMENT IN THE AIR-COOLING ZONES DOWNSTREAM OF THE LEHR ON A FLOAT GLASS PLANT
Frequent, accurate measurements of the temperature profile are necessary to reduce stresses in the glass and to optimise the cooling rate over the entire process length. Read More >
Measurement at the batch inlet provides thermal monitoring of the glass raw materials for quality control. We recommend the LWIR-640 thermal imager or RT8 thermometer for this application.
Optimum process control, energy efficiency and tank condition can be controlled through refractory wall measurements. The NIR-B Glass, Cyclops 100L, Model FG and SPOT M100 are recommended.
An LWIR-640 thermal imager is recommended for continuous monitoring of the melt tank exterior. This monitors the tank condition, providing warnings of possible glass break-out or refractory failure.
Accurate, reliable temperature measurements are essential for this important area of the tank. The solutions recommended by AMETEK Land are the Model FG, SPOT M100 and Lancom 4.
Glass production produces flue gas emissions which must be monitored. We offer the Lancom 4, Model 4500 MkIII and WDG 1200/1210, depending on process needs.
The canal links the melt tank exit to the tin bath. We recommend the Model FG or SPOT M100 thermometer for bulk temperature measurement of the glass here.
To produce glass of consistently high quality, it is vital to understand the temperature profile at this point where the glass solidifies on molten tin. A FLT5A thermometer is recommended.
Measurements at the exit of the tin bath provide important product quality information ahead of the annealing process. Our recommended solutions are the LSP-HD 50 linescanner and FLT5A thermometer.
Accurate measurement of the temperature profile is vital during cooling. The FLT5A thermometer, LSP-HD 5FL linescanner and JRG/A application-specific thermometer are recommended to provide this essential monitoring.
Air nozzles must cool the glass in a uniform way before it is cut to size. Our recommended solutions are the LSP-HD 61 linescanner and RT8 thermometer.
Measurements at this stage ensure safe cutting and provide a quality control check. We supply the LSP-HD 60 linescanner and RT8 thermometer for this application.
