Flat Tempering

Experimental Investigation of Residual Stresses in Toughened Glass

Jens Henrik Nielsen, John Forbes Olesen, Henrik Stang, Department of Civil Engineering, Technical University of Denmark

Toughened glass is often used in load carrying elements due to the relatively high tensile strength compared with float glass. The tensile strength of toughened glass is a combination of the pure material strength and the residual stresses imposed by the toughening process. This paper is concerned w...

How to Affect Residual Stresses in Glass Tempering

Antti Aronen & Reijo Karvinen, Tampere University of Technology,Finland

In order to stand high loadings, the glass used in windows and glass constructions must be tempered. In the tempering process the purpose is to create a compressive stress near the glass surface. This can be achieved with proper control of heat transfer, which effects the stress distribution in glas...

The Critical Relationship Between Glass Surface Quality and The Tempering Rollers

Bill Zhao & Ren Bartoe

The author discusses the critical physical and chemical properties of fused silica ceramic rollers used in the horizontal heat-treating process for safety glass. Those properties coupled with the care and maintenance of rollers and the operating parameters of the tempering furnace are directly assoc...
