| 摘要 |
An electric reduction furnace with a furnace vessel having a refractory lining and electrodes which are connected to a three-phase current power supply unit and which extend into the furnace vessel. In the region between, in each case, two first electrodes (21-22, 22-23, 23-21) and the wall of the furnace vessel, additional second electrodes (31-33) ae provided which form with each two of the first electrodes substantially isosceles triangles. The additional second electrodes (30-33) extend substantially parallel to the first electrodes (21-23) and are electrically connected to the furnace lining (14).
