Explanation for edge bending of glass in tempering furnace

Antti Aronen

A good visual quality is of great importance in tempered glass. Roller waves and other deformations are formed easily in the glass during the tempering process. In order to understand the formation of deformations a theoretical model is needed. The influence of heat transfer, rollers and processing parameters such as velocities and oscillation during the heating period can be studied using a theoretical model. Some examples of glass behavior during the heating period in high temperatures are presented in the paper. On the basis of examples a great influence of temperature and time on the visual quality can be seen.
