PCT No. PCT/AT95/00237 Sec. 371 Date Jun. 2, 1997 Sec. 102(e) Date Jun. 2, 1997 PCT Filed Nov. 30, 1995 PCT Pub. No. WO96/17092 PCT Pub. Date Jun. 6, 1996A plant for producing metal includes a electricity supply system and a direct-current electric arc furnace connected thereto, where in order to make do with an electricity supply system possessing a relatively small short-circuit capacity, the direct-current electric arc furnace has at least two electrodes and the electricity supply system has a system short-circuit capacity Sk which is at least equal to wherein Si is the nominal power per electrode and i represents an index for the electrodes that varies from 1 up to the maximum number of electrodes in the direct-current electric arc furnace.
