A method for controlling discharging of a glass plate in a glass plate tempering technology process is provided. After a glass plate is fed into a heating furnace, a monitoring unit monitors and performs filtering on a working parameter of a heating element in real time, and then transmits the filtered working parameter to a control unit. The control unit compares the filtered working parameter with a specified threshold. After the working parameter reaches a maximum value or a minimum value, and then reaches the specified threshold during a subsequent change, the control unit sends an instruction to a drive mechanism. The drive mechanism acts to move the glass plate out of the heating furnace directly or after a time delay, so as to complete a glass plate heating process. The present disclosure changes a conventional time-based control method, reduces energy consumption, and improves quality of a tempered glass. 1. A method for controlling discharging of a glass plate in a glass plate tempering technology process , using a heating furnace configured to heat a glass plate , wherein the heating furnace comprises a monitoring unit , a control unit , and a drive mechanism , the method comprising:upon determining that the heating furnace is run to reach a working temperature in a no-load state, inputting a corresponding value of a working parameter of a heating element to the control unit to set a threshold;performing a filtering on a detected working parameter of the heating element detected by the monitoring unit to obtain a filtered working parameter, in a process of heating the glass plate in the furnace after the glass plate is fed into the heating furnace;transmitting the filtered working parameter of the heating element to the control unit;comparing the filtered working parameter of the heating element with the threshold by the control unit;sending an instruction to the drive mechanism by the control unit, after the filtered working parameter of the heating ...

Tempering section of a flat glass tempering machine saves energy and reduces peak power by shutting an area of tempering section in the areas where there is no glass. The tempering section is multipurpose so that the first part can be used as a high pressure section for tempering thin glasses, latter section being after the cooling section. Further, the high pressure section can use air produced by a blower and/or compressor. 1. A tempering section of a flat glass tempering furnace , which tempering section comprises rollers for oscillating the glass to be tempered , at least one pressure chamber where tempering air is guided , nozzle boxes parallel to the rollers and attached to the pressure chamber and nozzles at the ends of the nozzle boxes through which nozzles air is blown against the glass , whereby at least some of the nozzle boxes are provided with dividing walls each dividing wall separating an end of the nozzle box from the center of the nozzle box , the tempering section further comprising shutting devices for preventing the tempering air from entering into the ends of the nozzle boxes thereby reducing the width of the tempering area of the tempering section.2. A tempering section as claimed in claim 1 , wherein the front end of the pressure chamber (Ps) is provided with a wall (Whp) dividing a high pressure area (Thp) from the rest of the pressure chamber (Ps) the wall comprising at least one shutting device.3. A tempering section as claimed in claim 1 , wherein the tempering section comprises means for guiding compressor air at least to a part of the tempering section.4. A tempering section as claimed in claim 1 , wherein the back end of the pressure chamber comprises a wall for preventing air from entering to the last nozzle boxes whereby the tempering section further comprises shutting devices allowing and preventing the air from entering the last nozzle boxes as per need.5. A tempering section as claimed in claim 1 , wherein the tempering section ...
