摘要： An electrode adjustment device and a vehicle positioning system for positioning the electrode adjustment device adjacent a furnace. The electrode adjustment device is utilized for adjusting the electrode during maintenance of the furnace (e.g., removal of the electrode for replacement or repair, repair of the refractory material, or other like furnace or electrode repair). When the electrode adjustment device is moved to a location adjacent the furnace, it is used to apply force under the bottom electrode to break the connection between the bottom electrode and the furnace. After the connection is broken the bottom electrode is pushed up into the furnace vessel by the electrode adjustment device until the electrode can be removed. After removing the bottom electrode, the electrode adjustment device is covered with debris and can be cleaned adjacent the furnace.

摘要： An electrode column and a method of determining the length of the electrode in it in an active furnace. The column is a Söderberg column including a mantel in which the electrode is movable in an axial direction by lower and upper slipping clamps which are movable relatively to each other by slipping cylinders. The method includes the steps of moving, with the slip clamps, the electrode in a downslip relatively to the mantel with the slipping cylinders and gravity and measuring the force required to move the electrode with only the upper slipping clamp against predetermined reaction forces acting against movement of the electrode and computing these parameters to determine the mass and so the length of the electrode relatively to the theoretical mass of the undamaged electrode at the time of movement.

摘要： A metallurgical vessel heated by direct current, particularly for the production of ferroalloys, including a metallic jacket lined with refractory material and a bottom electrode. A bottom electrode (22) is located within the interior of the vessel and arranged below a refractory side wall (12) of the metallurgical vessel (10). Bottom electrode (22) is constructed from electrically conducting refractory material. The periphery of the electrically conducting bottom (22) is surrounded by metallic plates (25), each of which is connected to current rods (31) which extend through a metallic jacket (11) and out from the vessel. Plates (25) and current rods (31) are separated from the metallic jacket (11) by electrical insulation (32). The electrode device in the bottom of the vessel ensures electrical contact over as large an area as possible. In addition, reliable current transfer between the melt and the electrode device in the bottom of the vessel is ensured in the case of a power supply lead which is independent of the thermal load on the refractory lining.

摘要： Process and apparatus for the continuous melting of scrap in an electric D.C. furnace, in which the D.C. source (23) supplies vault electrodes (4) and hearth electrodes (8) by means of respective feed conductors (7) and return conductors (9). The scrap is fed through an orifice (12). The vault electrode or electrodes (4) are arranged on the other side of the axis of the shaft (1) in relation to the orifice (12). The hearth electrode or electrodes (8) are offset towards the orifice (12), and the return conductor or conductors (9) connected to the hearth electrode or electrodes (8) are led under the bottom (2) of the shaft (1) and as near as possible to the latter, being directed towards the opposite zone of the furnace where the vault electrodes (4) are located, as to generate magnetic fields capable of deflecting the arc or arcs towards a zone set apart from the vault electrodes (4) and located substantially below the scrap feed orifice (12 ).
