摘要： An energy-efficient device for refining a glass melt to produce a glass and/or a glass ceramic is provided. The device includes a refining crucible defined at least by lateral walls with a metallic lining as a melt contact surface, so that a melt refining volume is defined by a base surface, a top surface and a circumferential surface; at least one heating device that conductively heats the lining by an electric current in the lining, so that the melt is heated through the lining, the heating device and the lining are connected to one another by a feeding device. The feeding device establishes contact with the lining so that an electric current runs from the top surface to the base surface or from the base surface to the top surface, at least in sections of the lining.

摘要： A hot forming unit or debiteuse for plate glass production, with a noble metal box or frame encompassed by and contained in a highly heat-resistant ceramic frame and having a drawing slot matched to a cross section of a plate glass sheet to be produced. The dimensional integrity of the drawing slot of the noble metal frame is assured because the ceramic frame is constructed of longitudinal components and lateral components, where the longitudinal components of the ceramic frame and the longitudinal legs of the noble metal box rest against one another and are held so that they can still move axially against each other in a limited fashion. The longitudinal legs of the noble metal box are held in a stretched position by tension springs.

摘要： The invention relates to a method and a device for refining a glass melt, using negative-pressure apparatus. According to the invention, the glass melt is fed to a refining bench by means of an uptake pipe and is discharged from the refining bench by means of a downpipe, a negative pressure being created over the flow of glass in the refining bench. The invention is characterised in that the uptake pipe and/or the downpipe and/or the refining bench has/have at least one component consisting of at least one refractory metal and/or of a refractory metal alloy as the glass contact material.

摘要： The apparatus for reduced-pressure refining of a glass melt includes a refining bank formed so that a reduced pressure is generated by a glass flow in it. The refining bank has a component, which is made from a refractory metal or refractory alloy acting as glass-contact material. The refractory metal or alloy contains molybdenum, tungsten, tantalum, and/or hafnium. The device of the present invention includes a protective gas reservoir for a protective gas and an automatically operating valve connecting the reservoir with the refining bank so that an inner side of the component that would otherwise be exposed when a pressure rise or a falling glass melt column occurs is protected from oxidation by the protective gas. A process for using the device during refining of the glass melt is also part of the invention.
