Depending on the nature of the glass, for the same formula, different thicknesses of glass, the steel stress mainly related to the cooling rate. The heat stress formula, if we want the same size steel surface stress, the cooling rate of the square is an inverse relationship between the thickness of the glass. For a steel device, the cooling air outlet gate area is constant, in air temperature and a hair away from certain situations, the cooling rate of stress-related hair only.

In order to get a good quality glass exterior, glass baked at a temperature of steel to meet the requirements of the premise should be as low as possible, so to reduce heat loss during glass baked, baked faster glass after glass furnace cooling to begin as soon as possible. When the inner and outer layers of glass temperatures below the glass transition temperature, can be considered a glass tempering phase is complete, you can cool down on the glass.
