ISOTHERMAL DROP SPEED COOLING METHOD OF FORCED CONVECTION AREA OF LIER AND APPARATUS FOR SAME

摘要

An isothermal drop speed cooling method of the forced convection area of a lier and an apparatus for same. A glass ribbon carried with glass passes through the forced convection area of the lier, 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 traveling direction of the glass ribbon, so that the cooling air volume from the front to the back can be gradually increased, thereby allowing the temperature drop speed of a glass plate to be uniform from the front to the back. The cooling method improves the phenomenon of that the cooling speed of the traditional glass ribbon is high at the front and low at the back.
