Abstract
The invention provides a molding method for plate glass. The method has a procedure that a support roll is used to suppress shrinkage in the width direction of a plate-shaped molten glass ribbon. The support roll has in the tip section thereof a rotating member that comes in contact with the molten glass ribbon. The rotating member does not have an internal coolant flowpath and is formed using a ceramic material. The outer peripheral surface of the rotating member has a whole peripheral bent cross section shape protruding towards the radial outward. The support roll is used in an area where the viscosity of the molten glass ribbon is 106.5-1013dPs.s.
Description
[0001] This application is submitted on April 21, 2014, the application number is 201280051763.8, and the title of the invention is "backup roll, forming device of plate glass with support roll, and forming method of plate glass using support roll". Divisional application. technical field [0002] The invention relates to a forming method of plate glass. Background technique [0003] As a forming method for plate glass, the float method is widely used. The float method is a method in which molten glass introduced onto molten metal (for example, molten tin) accommodated in a bath flows in a predetermined direction to form a ribbon-like molten glass ribbon. After the molten glass ribbon is cooled while flowing in the horizontal direction, it is pulled up from the molten metal by a lift-up roll, annealed in an annealing furnace, and becomes sheet glass. After the sheet glass is carried out from the annealing furnace, it is cut into a predetermined size and shape by a cutting ...
