Manufacturers can monitor the temperature of materials and machines using non-contact infrared (either pyrometers or thermal imagers) to ensure products will meet quality standards and market requirements.
Melting Tank
WHAT TO MEASURE
- The roof and end-wall temperatures to monitor for potential refractory failures.
- The tank bottom temperature to monitor for the erosion of the refractory lining.
- The material temperature to ensure a uniform melting process that remains within the desired temperature thresholds.
Flat Glass Production
Once the glass ribbon is formed, it moves to the annealing lehr where it can cool slowly. Ensuring the proper temperature of the cooling zones is essential to maintaining uniformity.
WHAT TO MEASURE
- The glass temperature in the canal, to ensure that the glass discharged by the melting furnace reaches the minimum required temperature before reaching the glass bath.
- The temperature distribution in the heating zone of the tin bath, to ensure the necessary temperature distribution.
- The temperature distribution across the flat glass ribbon, to ensure the proper temperature as it leaves the working tank.
- The surface temperature in the annealing lehr, to relieve all mechanical stress induced in the glass before further processing and packing.
- The annealing lehr discharge temperature, to ensure the required glass temperature after the cooling phase.
Container Glass Production
The glass gob and glass mold temperatures are very important to ensure a stable quality of the production of container glass.
WHAT TO MEASURE
- The temperature distribution of the molten glass exiting the working tank to ensure uniformity.
- The temperature gradient in the feeder to ensure continuous control of the material flow and minimize heating process costs.
- The core gob temperature to ensure the desired viscosity of the glasses.
- The mold temperature for quality control.
- The final check of materials to ensure they adhere to desired specifications.
