New Horizons in Glass Processing

Vlad Sklyar & Mike Shevelev, Gyrotron Technology, Inc

New ways of treating glass by high frequency microwave (HFM) are described. Solution of heat equation with HFM as a heat source allows selecting the HFM optimal parameters such as uniformity, frequency and power density for thermal processing of automotive glass. Computed and experimental data for optimal parameters are shown for different processes: shaping, bending, and tempering. Shaping with HFM can be accomplished without the use of conventional tunnel-type furnaces. For bending, local overheat of the necessary areas can be carried out with a speed of dozens of feet per second and tempering thin glass with thickness less than 2 mm and small size becomes possible.
