    摘要: Methods and apparatus for controlling glass flow in, for example, a downdraw glass manufacturing process (e.g., the fusion downdraw process) are provided. In certain aspects, the mass, thickness, and/or the temperature distribution of molten glass (40) on the surface of forming apparatus (60) is managed by: (A) constructing a stream-tube mapping between (i) regions (510; FIG. 5A) of a cross-section of a conduit (400) that supplies molten glass (40) to the forming apparatus (60) and (ii) regions (510; FIG. 5B) on the exterior surface of the forming apparatus (60); (B) using the stream-tube mapping to select a temperature distribution for the cross-section that results in a desired mass, thickness, and/or temperature distribution of molten glass (40) on the surface of the forming apparatus (60); and (C) heating and/or insulating the conduit (400) so as to produce a temperature distribution for the cross-section which equals or at least approximates the distribution selected in step (B).

    摘要: An apparatus for forming a glass sheet with reduced thermal coupling between upper and lower regions of the apparatus is disclosed. The apparatus allows for temperature changes near the lower regions of the enclosure without a large temperature impact on the upper regions of the enclosure, thereby providing for greater flexibility in setting a temperature profile for a forming body located within the enclosure.

    摘要: In the formation of sheet material from molten glass, a cooling tube is positioned in the forming area for directing a flow of cooling gas on discrete portions of the molten glass proximate a draw line or root to control local thickness variations in the sheet and thereby provide a uniform glass sheet thickness across the width of the sheet. The cooling tube is disposed in a pivot member configured to rotate about at least one axis, thereby causing an end of the cooling tube to direct the cooling gas over a wide range of angular positions across a portion of the width of the molten glass flowing over and from a forming body.

    摘要: Disclosed is an apparatus for producing a glass sheet comprising lower thermal shields positioned below cooling doors for minimizing radiative heat loss from a forming body used to form a ribbon of molten glass from which a glass sheet is cut, and upper thermal shields positioned between the cooling doors and a root of the forming body for minimizing radiative heat loss from the forming body. The thermal shields are typically arranged as pairs and positioned on horizontally opposite sides of a flow of molten glass descending as a continuous ribbon from the forming body. Each thermal shield of the lower and upper thermal shield pairs may comprise a plurality of segments, including end segments and a central segment, wherein the end segments may be separately movable relative to the central segment, allowing an edge of the thermal shield adjacent the ribbon to be varied.
