METHOD FOR FORMING REFRACTORY MOLDED PRODUCT FOR BEING MOUNTED IN PLATE GLASS MOLDING APPARATUS AND REFRACTORY MOLDED PRODUCT, AND METHOD FOR MOLDING PLATE GLASS AND PLATE GLASS

摘要

PROBLEM TO BE SOLVED: To provide a method for forming a refractory molded product for being mounted in a plate glass molding apparatus that is used for a long period of time and molded highly precisely even when it has complicated shape and a refractory molded body, and a method for molding plate glass by an apparatus in which this refractory molded product is mounted and plate glass obtained by this method.;SOLUTION: The method for molding a refractory molded product 10 for being mounted in a plate glass molding apparatus is provided in which there is, by casting, fabricated the refractory molded product 10 having, on its top portion, a trough-shaped molten glass-supplying groove 10a of which the upper portion is opened, both sidewall top edges 10b as an overflow weir, and both sidewall external surfaces 10c terminated at a lower end 10d so as to have a cross sectional surface of substantially wedge shape, wherein the refractory molded product 10 for being mounted in a plate glass molding apparatus has a dimension of 1,500 mm or more in the long length direction of the refractory molded product 10. The method for molding a glass plate comprises supplying alkali-free glass into the refractory molded product 10, and adjusting heating and cooling conditions or the like so that the thickness dimension of the plate glass becomes a predetermined thickness of 0.7 mm or less, thereby molding the plate glass.;COPYRIGHT: (C)2007,JPO&INPIT
