A glass sheet forming and annealing system disclosed provides control of edge stresses by maintaining a press formed glass sheet on an annealing ring (72) below a heated upper forming mold (58) within a forming station (12) for slow cooling toward the glass strain point temperature.

Glass laminates, comprising more than one glass composition, are becoming increasingly common as the industry moves towards lighter and stronger glazing. Bending dissimilar glass compositions can present problems. A mismatch in the glass viscosity curves, especially in the viscoelastic region of the compositions can result in one layer becoming softer than one of the other layers during the thermal bending process. As a result, economical processes, such as gravity or press bending in which multiple glass layers are simultaneously bent, may not be practical to use forcing the use of more expensive single glass layer bending processes. By thermal treatment processes the fictive temperature of at least one of the glass compositions prior to bending can be shifted to better match the other compositions allowing the glass layers to be simultaneously bent.

In a method for tempering a glass sheet, based on identified glass sheet properties, a tempering furnace temperature and/or glass sheet heating time are adjusted, the blowing pressure and/or distance of cooling unit air jets are adjusted, the glass sheet is heated in a tempering furnace, the achieved temperature is thereafter measured from the glass sheet surface, and the glass sheet is cooled. The development of the thickness direction temperature profile of the sheet during the tempering cooling is calculated, the residual stress profile achieved in the glass sheet during tempering is calculated, a reference variable for the glass sheet tempering level is selected and the selected reference variable is compared to a predetermined threshold value. If the comparison between the reference variable and the threshold value fulfils a predetermined criterion, an alarm is created and/or the glass sheet is found not to qualify as safety glass.

An actuating mechanism control method for a glass plate tempering process, comprising: after a glass plate is conveyed into a heating furnace, a monitoring unit monitors in real time energy consumed by a heating element of the heating furnace, and sends the energy consumed to a control unit to compare with a set threshold; and when the energy consumed by the heating element of the heating furnace is greater than or equal to the set threshold, the control unit sends an instruction to an actuating mechanism to control actions of the actuating mechanism to complete a corresponding tempering process procedure. Through the method that the monitoring unit monitors in real time the energy consumed by the heating element of the heating furnace, a heating procedure of the glass plate is more scientifically and precisely controlled, and, therefore, a discharging moment of the glass plate can be accurately determined.
