Study of Glass Spray Tempering Process

Abstract

Abstract: The spray tempering process is theoretically more energy-efficient than the air-cooled tempering process. In order to investigate the actual energy-saving effect of the spray tempering process, the plate glass with dimension of 40 mm×40 mm×5 mm were used for air-cooled tempering and spray tempering tests. The results show that compared with air-cooled tempering process, the spray tempering process saves at least 25.06% energy during cooling. The spray tempering process improves the tempering degree of glass, that is, the particle number of broken increases by at least 8.91%, the surface compressive stress increases by at least 12.12%. With the increase of mist load fraction, the cooling time decreases, and the energy saving effect and tempering degree increase.

Key words: spray tempering, air-cooled tempering, energy consumption, tempering degree, particle number, mist load fraction
