The online stress calculation solution uses measured process data to calculate temperature and stress distribution in the quenching part of the tempering process.
The glass temperature after the furnace is taken as the initial temperature. Then, the cooling pressure and other chiller measured values are used to calculate the glass temperature and stress distribution and represent these in a physical model. The results allow estimating the stress level of each glass.
Knowing the stress level is important for monitoring the glass quality for safety. It also allows taking effective actions immediately if any variations on the end product stress level are detected.
Stress calculation is part of Glaston’s continuous development work of increasing the level of automation toward fully automated solutions.
