| 摘要 |
The invention relates to a glass melting device comprising a furnace which includes electrodes that are in contact with the mass of vitrifiable materials, further includes a lateral opening that is connected to a duct distributing melted glass, and a removable barrier that penetrates into the glass in or upstream of the opening in such a way that a vertical plane extending along the upstream surface of the barrier touches the largest horizontal circle that can be drawn furthest downstream in the furnace without taking into account the barrier, said largest circle being at the level of the highest side of the bottom of the duct. The device provides good-quality glass that can be fed to a fiber-producing device. |
