STRUCTURE, FLOAT SHEET GLASS MANUFACTURING APPARATUS, BUBBLE FLOATING SUPPRESSING METHOD, AND FLOAT SHEET GLASS MANUFACTURING METHOD

摘要

A structure, a float sheet glass manufacturing apparatus, a bubble floating suppressing method, and a float sheet glass manufacturing method. The porous structure (12) disposed in a bathtub (14) in the immersed state in a molten metal (16) filled therein and formed of a material non-affinity to the molten metal (16). A hollow passage (42) communicating with an atmosphere space is formed in the structure (12), and gases produced on the outer surfaces of the structure (12) in contact with the molten metal are led into the hollow passage (42) to suppress that the gases are floated in the form of air bubbles from the outer surfaces of the structure (12).
