Abstract
A d.c. arc furnace for metallurgical purposes includes two or more electrodes arranged on the furnace vessel and projecting into the furnace vessel. To avoid actions of forces departing from the magnetic fields derived form the currents conducted to the electrodes and effecting deflections of the electric arcs, the electric supply means provided for each of the electrodes are each arranged in the immediate vicinity of the electrode to be supplied, the electric supply means of one electrode being arranged so as to be spacially separated from the electric supply means of the remaining electrodes, viewed in the peripheral direction of the furnace vessel.
Claims10
A d.c. arc furnace for metallurgical purposes comprising a furnace vessel having a vertical axis, a periphery around the axis and the periphery defining an interior of the vessel;
- at least two electrodes arranged on the furnace vessel and projecting into the interior of the furnace vessel;
- a respective electric supply provided for each of the electrodes, each supply comprising an electrical device and a high current line from the device to the electrode, each electrical device being arranged in the immediate vicinity of the respective electrode to be supplied by the device through the respective high current line, the electrical device for each electrode being arranged so as to be spatially separated from the electric devices of the electric supplies for the other electrodes around the periphery of the furnace vessel.
