Abstract
An isothermal drop speed cooling method and an apparatus for same. A glass ribbon carried with glass passes through the forced convection area of the glass annealing lehr, and the glass ribbon is moving while the glass is being air-cooled in the forced convection area. The glass is air-cooled by different air volume according to the temperature of the glass, so that the glass is allowed to be cooled at isothermal drop speed during the moving process of the glass. According to the cooling method and apparatus, the specification size of the opening section of multi-row air nozzles longitudinally arranged is increased along the moving direction of the glass ribbon, so that the cooling air volume from the front to the rear can be gradually increased, thereby allowing the temperature drop speed of a glass plate to be uniform from the front to the rear.
