    摘要: The apparatus for reduced-pressure refining of a glass melt includes a refining bank formed so that a reduced pressure is generated by a glass flow in it. The refining bank has a component, which is made from a refractory metal or refractory alloy acting as glass-contact material. The refractory metal or alloy contains molybdenum, tungsten, tantalum, and/or hafnium. The device of the present invention includes a protective gas reservoir for a protective gas and an automatically operating valve connecting the reservoir with the refining bank so that an inner side of the component that would otherwise be exposed when a pressure rise or a falling glass melt column occurs is protected from oxidation by the protective gas. A process for using the device during refining of the glass melt is also part of the invention.

    摘要: The suction feeder for glass processing includes a housing containing a material; a heatable noble metal or noble metal alloy feed line embedded in the housing in a thermally insulated fashion; a connection element at one end of the feed line for connection with a molten glass supply device and an outlet element for operative engagement with a suction device at the other end of the feed line. To prevent aspiration of bubbles through the feed line the material together with the housing surrounds the heatable feed line and has a composition and/or structure such that in operation a negative pressure can be produced on an outer side of the feed line. Preferably this negative pressure is lower than a minimum internal pressure within the feed line that is established during a suction process.
