Abstract: Improved glass-melting technology, intelligent process
control, glass quality control, and establishing novel melting conditions,
are realized by different kinds of physicochemical models. The model
application is preceded by the analysis of homogenization processes,
i.e., heating, dissolution, or vitrification and refining. The energy
consumption of the process, the pull rate and size of the melting space,
and glass quality are the main technological factors taken into account.
In the following step, the optimum conditions are applied to simplified
and complex models or processes. The mentioned models are mostly represented
by systems containing melt and numerous inhomogeneities (solid particles,
bubbles).
