GLASS MELTER, GLASS FIBER PRODUCTION APPARATUS, AND GLASS FIBER PRODUCTION METHOD

摘要

A glass melting furnace is heated to the melting point of silica or hotter and the melting time of glass material is reduced, and the amount of insufficiently melted glass material is reduced. A glass fiber production apparatus (1) is provided with: a glass melting furnace (11) provided with a floor (12) and a side wall (13) that are formed from an electrically heated member, and having a molten glass outlet (15) formed in the floor (12); an injection opening (19) that injects glass material into the glass melting furnace (11) and covers the glass melting furnace (11); and a casing (18) in which a discharge opening (23), for discharging molten glass emitted from the outlet (15) of the glass melting furnace (11), is formed. Therein, the inner surface of the side wall (13) and the floor (12) is coated with boron nitride. Additionally, electric current-caused resistance heating in the glass melting furnace (11) causes glass material injected into the glass melting furnace (11) to be melted.
