摘要： A process is disclosed for melting scrap metal. Threephase current is rectified to direct current by thyristors and is led through a cathode, through the material contained in a metallurgical vessel and through a bottom electrode designed as an anode. In order to actively influence the combustion by the electric arc and to attain the metallurgically highest possible power input by simple means, the power current is led through a group of at least two thyristors controlled by individually adjustable control currents; the negatively polarized power current is fed back to the melt by a common electrode and the positively polarized power current is independently fed back to the melt from the bottom of the vessel through at least two anodes.

摘要： In order to reduce the ohmic and inductive losses associated to the high current between the transformer and the electrodes (4, 5) of an electric oven (1), there are used, instead of cables, rails (17, 21) supplied by the source and on which sliding contact elements (17, 21) are applied by springs. The contact elements are designed so as to allow a lifting motion of the electrodes and a slight tilting of the oven. A mechanical separation of the contact allows the rotation of the cover without any obstacle for reloading the oven.
