    摘要: For permitting temperature manipulation of a melt even at a conductivity below 10−1 Ω−1 cm−1 and thus permitting refining of the melt at temperatures about 1700° C., the invention provides a method and a device for temperature manipulation of a melt (16), in particular in a refiner unit. The melt (16) is heated at least by ohmic resistance heating with at least two electrodes (4) that are arranged in the melt (16). At least a part of the melt (16) is cooled. The device (1) for temperature manipulation, refining, purification and homogenisation of a melt (16) comprises at least one arrangement for accommodating melt material (36, 16), defining an inner chamber, and at least two electrodes (4) for ohmic resistance heating of the melt (16). The electrodes (4) project into the inner chamber of the arrangement, in particular of a vessel (2).

    摘要: An electrode holder for use in a furnace for melting a batch material to form molten glass is disclosed comprising a refractory coated nose member presented to and in contact with a molten glass material contained within the furnace. The refractory coating is preferably a flame- or plasma-sprayed ceramic such as alumina or zirconia. That protects the nose member from corrosion from the hot molten glass.
