摘要： A DC arc or resistance melting furnace has a current supply line and a coolant supply line located in the furnace heart in the connection is constructed so that a point of separation is provided between an attachment assembly for the current and cooling lines and the vessel. The attachment assembly is formed at the terminal and fastened to the furnace vessel at a contact point. When changing the contact electrodes, it is a simple matter to undo the point of separation of the electrodes from the assembly without removing the coolant lines or the whole assembly may be removed.

摘要： A direct-current electric arc furnace for melting metals, including a furnace vessel and at least a pair of electrodes, wherein a bottom electrode is mounted in the bottom of the furnace vessel. In order to be able to remove the bottom electrode, the cross-section of which tapers towards the interior of the furnace vessel, from the outside in the direction of the furnace vessel interior, the bottom electrode is provided with a molded body of a refractory material. The molded body envelopes the bottom electrode and in combination therewith forms an electrode unit. This electrode unit in turn has a cross-section which expands in the direction of the furnace vessel interior or at the most remains the same. In this way, extensive work can be saved by removing the bottom electrode from outside into the interior of the furnace. Removal of the bottom electrode is also facilitated by the fact that neither a connecting piece for applying power to the electrode and for cooling thereof nor the electric feedlines thereto need be removed.
摘要翻译：一种用于熔化金属的直流电弧炉，包括炉容器和至少一对电极，其中底部电极安装在炉容器的底部。为了能够去除其底部电极，其横截面朝向炉容器内部的外部沿着炉容器内部的方向从外部逐渐变细，底部电极设置有耐火材料的成型体材料。成型体包封底部电极并与其组合形成电极单元。该电极单元又具有在炉壳内部的方向上膨胀的截面或最多保持相同的横截面。以这种方式，通过将底部电极从外部移除到炉内部可以节省大量的工作。通过以下事实也可以去除底部电极，即，不需要去除用于向电极施加电力并用于其冷却的连接片，也不需要去除电动馈线。

摘要： There is disclosed a method of operating a metallurgical plant including a metallurgical vessel through the ceiling of which one or several hollow electrode(s) are guided in whose cavity a supply pipe is liftably and lowerably moveable. The plant may be operated as an electric arc furnace to melt down charge materials and fluxes, by retracting the pipe mouth to behind the mouth of the hollow electrode. Or, it may be operated as a plasma furnace to melt charge materials and fluxes upon increased energy supply, by displacing the mouth of the pipe to or slightly in front of the mouth of the hollow electrode and simultaneously supplying a plasma generating gas. And, finally, it may be operated as a refining converter, by displacing the pipe mouth to beyond the mouth of the hollow electrode and supplying oxygen-containing gas while interrupting the current supply.

摘要： This invention relates to a water-cooled arc furnace electrode comprising a double-walled tubular metal column the two walls being electrically insulated from one another and defining an annular channel between them. The inner wall is electrically connected to a conductive screw-threaded member from which graphite sections depend, and this inner tube defines a central channel constituting a water flow path connected in series with the annular channel via a "spider" in the aforesaid member. In accordance with this design the volume of water contained within the electrode column approaches the maximum, ensuring adequate cooling during electrode changes which hitherto has presented problems in other designs of this component.
