Abstract

This work presents a simplified model for the determination of the engine power as a function of the residual stress using quench parameters by forced convection and introduces the necessary empirical equations of integral heat and mass transfer coefficients suggested by Martin (1977). For a residual stress dependent production of thermally tempered glasses, float glasses were thermally tempered due to heat treatment of the glass panes with different heat transfer coefficients. In the method presented, quench parameters for determining the engine power required to reach the target residual stresses are taken into account. The plausibility of the model is checked on the basis of experimental data.
