Problems solved by technology

However, for the device, it is disadvantageous that the electrodes cause heat loss
Firstly, starting is thus difficult because the electrodes are arranged in the lower area
In addition, especially when starting the equipment, there are problems caused by flashover

Embodiment Construction

[0162] For the configuration of the interior of the container according to the device according to the invention, rod-shaped electrodes or plate-shaped electrodes can be used in particular. exist figure 1 , a schematic selection of these electrodes 4 is shown. Rod electrodes can have a round shape ( figure 1 A), rectangle ( figure 1 B) or a polygon ( figure 1 C) Cross section. The geometry of the plate electrodes can also be varied. For example, when flow influence is required, a shape suitable for flow can be selected ( figure 1 D). Likewise, it is possible to use simple plate electrodes with bulk geometry ( figure 1 E). To influence the flow, very different shapes can be chosen, e.g. electrodes can also have curved cross-sections ( figure 1 F).

[0163] Regardless of the shape and geometry chosen for the electrodes 4 , the electrodes can have openings 41 inside them, through which a fluid for cooling the electrodes 4 can be piped. exist figure 2 In , an example ...

Abstract

A method and device are disclosed for temperature manipulation of a melt even with conductivity below 10<-1> O <-1>cm<-1>, thus permitting refining of the melt at temperatures above 1700 DEG C. According to the method for temperature manipulation of a melt (16), in particular, in a refiner unit, the melt (16) is heated at least by ohmic resistance heating, at least two electrodes (4) are arranged in the melt (16) and at least a part of the melt (16) is cooled. The device (1) for temperature manipulation and/or refining and/or purification and/or 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), wherein the electrodes (4) project into the inner chamber of the arrangement in particular of the vessel (2).

Description

technical field [0001] The invention relates to a method for temperature manipulation of a melt and to a method for clarifying and / or purifying a melt according to the preamble of claim 1 . Furthermore, the invention relates to a device for the temperature manipulation of a melt and / or for the clarification and / or purification of a melt according to the preamble of claim 62 and also to a product, in particular a glass product, according to The method of the invention carries out the melting and / or clarification and / or purification and / or preparation and / or the preparation is carried out in the apparatus according to the invention. Background technique [0002] In the first process step for producing glass, the starting substances, so-called glass mixes, are melted. Melting is performed in a tank kiln and is generally limited to melting temperatures of up to 1650°C due to the heat capacity of the wall material. When the mixture becomes fluid with increasing temperature, the...
