玻璃板的退火方法及其装置
摘要：
本发明提供一种能将形成于玻璃板的I/T充分减小的玻璃板的退火方法及其装置。根据本发明的玻璃板(G)的退火方法，在被加热而弯曲成形的玻璃板(G)载置于成形模(16)的状态下，首先，利用冷却装置(20、22)对玻璃板(G)的被顶起区域进行冷却，以使被顶起区域处于应变点以下的低温状态。接着，在该状态下驱动顶起构件(36)，利用杆(38、38…)将玻璃板(G)的被顶起区域顶起，以将玻璃板(G)推离成形模(16)。
摘要（英）：

Disclosed are a method and device for gradually cooling a glass plate, whereby it is possible to ensure that the glass plate has a sufficiently low inner tension. The disclosed method for gradually cooling a glass plate (G) is configured so that while a glass plate (G) that has been heated and molded into a curved shape is mounted on a mold (16), the regions of the glass plate (G) to be pressed upwards are cooled to a temperature lower than the strain point by means of cooling devices (20, 22). Subsequently, the pressing member (36) is driven so that the region of the glass plate (G) to be pressed upwards is pressed upwards by means of rods (38, 38), and the glass plate (G) is separated from the mold (16).
