Apparatus for conveying molten glass includes an electrical flange attached to a metallic vessel and an electrical flange support apparatus coupled to an electrode portion of the electrical flange and configured to prevent distortion of the metallic vessel and misalignment between the metallic vessel and an adjacent metallic vessel. A bracing assembly is also disclosed.

Assembly for supporting an electrical flange in a glass manufacturing apparatus

Apparatuses for interfacing with an electrode provided with a melting furnace including a vessel and an electrode. In some embodiments, a support assembly () supports the electrode outside of the vessel, and includes a cart () or similar apparatus that permits or facilitates selective vertical movement of the electrode and selective transverse movement of the electrode. In some embodiments, a push assembly () interfaces with a rear face of the electrode outside of the vessel, and is operable to apply a pushing force onto the rear face. The push assembly can include one or more tracks (e.g., threaded screw) that supports a body between opposing arms of a fixed frame. The body can translate along the tracks to apply a pushing force onto the electrode.

Melting furnace electrode handling devices

Delivery apparatus include an electrical circuit configured to heat a linear conduit and an elbow conduit. A first electrode can be mounted to an upstream portion of the linear conduit, a second electrode can be mounted downstream of the upstream portion, and a third electrode can be mounted to a curved segment of the elbow conduit within a footprint extension of a first passage of the linear conduit. In further examples, a delivery apparatus includes an electrical circuit with a first electrode mounted to an upstream portion of a linear conduit, a second electrode mounted to a downstream portion of the linear conduit, and a third electrode mounted to an elbow conduit. In still further examples, methods of heating molten glass include application of an electrical current such that neither a current flux through a linear conduit nor a current flux through an elbow conduit exceeds 8 amps/mm.

Delivery apparatus for a glass manufacturing apparatus and methods

Melters for glass forming apparatuses and glass forming apparatuses comprising the same are disclosed. According to one embodiment, a melter for melting glass batch materials includes a base portion and a rigid exoskeleton rigidly attached to the base portion and comprising a plurality of upright members interconnected with a plurality of cross members defining an exoskeleton interior volume. Connection nodes formed at intersections of the plurality of cross members with upper ends of the plurality of upright members are constrained from movement relative to the base portion in a longitudinal direction, a transverse direction, and a vertical direction. A tank assembly is positioned on the base portion in the exoskeleton interior volume and coupled to the rigid exoskeleton. In some embodiments, the melter has a dynamic resistance greater than 0.3.

Melters for glass forming apparatuses

A glass making process comprising a step of fining the molten glass in a fining vessel comprising a top wall portion not in direct contact with the molten glass, and a side wall portion in direct contact with the molten glass, wherein the top wall portion has a temperature T(top), the side wall portion has a temperature T(side), and T(top)&#x2212;T(side)&#x2266;10&#xb0; C., and a glass fining system. The invention is particularly useful for glass fining systems comprising a metal fining vessel made of precious metals such as Pt and/or Pt&#x2014;Rh alloys.

Process and system for fining glass

An oblong conduit () for conditioning molten glass is disclosed. The wall () of the conduit is composed of a precious metal, e.g., a platinum-rhodium alloy, and can be equipped with precious metal tabs () for supporting the upper surface () of the wall so as to reduce sag of that surface at such times as the conduit is at an elevated temperature and is not filled with glass. The precious metal tabs () can be received in channels () formed in a refractory support structure (). The refractory support structure () can be a laminate of two layers (), where one of the layers () has a smaller grain structure than the other layer (), the layers being held together by an adhesive ().

Methods and apparatus for thermally conditioning molten glass

Method for thermally conditioning molten glass

The present invention is directed toward a method of reducing contamination of a glass melt by oxide particulates, such as particulates of platinum oxide, which may condense on the inside surfaces of a stir chamber, particularly the stir shaft, and fall back into the glass melt. The method includes causing a flow of gas through an annular space between the shaft and the chamber cover. In one embodiment, the flow of gas through the annular space is caused by drawing a vacuum in the chamber. An apparatus for practicing the method is also provided.

Method and apparatus for homogenizing a glass melt

A system and method are described herein that control the environment (e.g., oxygen, hydrogen, humidity, temperature, gas flow rate, pressure) around one or more vessels in a glass manufacturing system. In the preferred embodiment, the system includes a closed-loop control system and a capsule that are used to control the level of hydrogen around the exterior (non glass contact surface) of the vessel(s) so as to suppress the formation of gaseous inclusions and surface blisters in glass sheets. In addition, the closed-loop control system and capsule can be used to help cool molten glass while the molten glass travels from one vessel to another vessel in the glass manufacturing system. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel(s) so as to reduce the oxidation of precious metals on the vessel(s).
