GLASS MELTING DEVICE, DEVICE FOR FORMING FIBERGLASS, AND METHOD FOR FORMING FIBERGLASS

摘要

In the present invention, the clarification and homogenization of molten glass are performed effectively in the case of having performed high-temperature melting. In the present invention, the inside of a glass melting furnace (11), which is provided with a side wall (13) and a bottom wall (12) to which an electric heating member that performs resistive heating by means of electrification is formed, a molten glass outlet (15) being formed to the bottom wall (12), is provided with: an upper partition plate (16) that allows the passage of molten glass only from the furnace inner bottom of the glass melting furnace (11); and a thin-film-forming member (25) that is disposed between the upper partition plate (16) and the outlet (15), holds back the molten glass, forms a passage with the upper partition plate (16) through which molten glass flows from below to above, and to which a thin-film-forming surface (25b) is formed that allows the overflowing molten glass to drop downwards and thus be formed into a thin film.
