    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a glass substrate which enables molten glass to be stirred homogeneously.SOLUTION: A stirring device 100 includes a chamber 1, and a stirrer 2 for stirring molten glass 7 in the chamber 1. The stirrer 2 includes a shaft 5, and blades 6a-6e arranged in a plurality of tires. In a stirring process, the stirrer 2 is rotated around the shaft 5 as the axis of rotation to transfer the molten glass 7 on an upper main surface of a main plate of the blade 6a arranged in the top to a shaft 5 side from the inner wall side of the chamber 1 thereby generating a circulating flow in the molten glass 7 between the blade 6a arranged in the top and the liquid surface of the molten glass 7, which flows upward along the shaft 5, toward the inner wall side of the chamber 1 from the shaft 5 side along the liquid surface of the molten glass 7, and toward the lower side of the chamber 1 along the inner wall of the chamber 1.
    • 要解决的问题:提供一种使熔融玻璃均匀搅拌的玻璃基板的制造方法。 解决方案:搅拌装置100包括腔室1和用于搅拌腔室1中的熔融玻璃7的搅拌器2.搅拌器2包括轴5和布置在多个轮胎中的叶片6a-6e。 在搅拌过程中,搅拌器2作为旋转轴围绕轴5旋转,以将熔融玻璃7转移到布置在顶部的叶片6a的主板的上主表面上, 从而在布置在顶部的叶片6a和沿着轴5向上流动的熔融玻璃7的液体表面之间的熔融玻璃7中朝向腔室的内壁侧产生循环流动 1,沿着熔融玻璃7的液面从轴5侧朝向腔室1的下侧朝向腔室1的下侧。版权所有(C)2012,JPO&INPIT
