    摘要: A glass-melting electrode has a cooling device. The glass-melting electrode has an electrode body with a blind hole, and the cooling device has a cooling tube which can be inserted into the blind hole in order to feed coolant into the blind hole. The cooling device has a flow distributor with at least three outlet openings. The flow distributor is arranged at an end of the cooling tube which has been inserted into the blind hole, such that coolant flows through the flow distributor into the blind hole.

    摘要: An electrode comprises a shaft extending from an electrode head. A cooling passage extends from an open end disposed at an attachment end of the shaft to a closed end, which is disposed within the electrode head. The electrode head is formed to have approximately a teardrop shape, which may be formed according to a radial profile rotated about a centerline of the shaft, where the radial profile has a center disposed within the electrode head and on the centerline. The radial profile may exhibit a single maximum within a middle portion of the radial profile. Alternatively, or in addition, the middle portion of the radial profile may be negatively curved.

    摘要: Methods and apparatus for producing display quality glass sheets are provided in which the batch materials for making the sheets are melted in a furnace whose glass-engaging surfaces comprise zirconia (ZrO2). By using molybdenum electrodes, instead of the conventional tin electrodes, to electrically heat the molten glass, the wear rate per unit area of the furnace's glass-engaging, zirconia-containing surfaces are reduced by more than 50%, thus reducing zirconia levels (solid+dissolved) in the finished glass by at least a similar amount. As a consequence of this reduction, rejection rates of finished glass sheets are lowered, which is of particular value in the production of glass sheets of large dimensions, as desired by display manufacturers and other users of such sheets.

    摘要: A flange (13) for use in direct resistance heating of a glass-carrying vessel (10), such as a finer, is provided. The flange comprises a plurality of electrically-conductive rings which include an innermost ring (140) which is joined to the vessel's exterior wall (12) during use of the flange and an outermost ring (150) which receives electrical current during use of the flange. The innermost ring (140) comprises a high-temperature metal which comprises at least 80% platinum and the outermost ring (150) comprises at least 99.0% nickel. This combination of materials both increases the reliability of the flange and reduces its cost. In certain embodiments, the flange can also include one or more rings (190) composed of a platinum-nickel alloy which has a lower thermal conductivity than platinum or nickel and thus can serve to reduce heat loss through the flange.

    摘要: A process for melting material to be treated includes placing material to be treated in a container that may include an insulating lining, heating the material to be treated and melting the material to be treated, preferably allowing the melted material to cool to form a vitrified and/or crystalline mass, and disposing of the mass. The mass is either disposed while contained in container or removed from container after cooling and disposed. Heat loss and melt-surface disruptions can be minimized with an engineered overburden material, which covers at least a portion of an exposed surface of the material to be treated.
