摘要:
Disclosed is an apparatus for conditioning molten glass. The apparatus includes a connecting tube assembly having a conduit for conveying the molten glass, the conduit (108) including at least two flanges (112, 114) and a sealing member (118) disposed between the at least two flanges (112, 114) around an outer peripheral region of the flanges, thereby forming an enclosed volume between an outer wall (110) of the conduit, the at least two flanges (112, 114) and the sealing member (118). An atmosphere within the volume may be controlled such that a predetermined partial pressure of hydrogen or a predetermined partial pressure of oxygen may be maintained within the volume. A current may be established between the at least two flanges to heat the conduit.

Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zum Homogenisieren eines fließfähigen Mediums, insbesondere einer Glasmasse. Um Schlieren zu beseitigen, die sich beispielsweise durch Verdampfung flüchtiger Bestandteile aus der Glasoberfläche bilden, wird gemäß der Erfindung vorgeschlagen, den Strom des fließfähigen Mediums umzulenken und zu beschleunigen.
摘要:
A glass forming apparatus for processing molten glass is disclosed comprising a delivery vessel for delivery molten glass to a forming body through a delivery conduit, the delivery conduit comprising a first portion have a circular cross-sectional shape, a second portion comprising a circular cross-sectional shape and a third portion comprising a non-circular cross-sectional shape. The delivery conduit further comprises a first transition portion coupling the second portion to the third portion, and a second transition portion coupling the third portion to an inlet of a trough in a forming body. Neither an inside bottom surface of the third portion, nor an inside bottom surface of the second transition portion, is lower than a bottom surface of the forming body trough. A method of processing molten glass is also described.
