Abstract
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).
Claims12
An electric reduction furnace for connection to a supply of electric current comprising a furnace vessel having a bottom and a wall lined with a refractory lining (14);
- a plurality of first electrodes (21, 22, 23) for connection to said electric current supply and extending into said furnace vessel;
- and a plurality of additional second electrodes (31-33) located in the region between every two of said first electrodes (21-22, 22-23, 23-21) and said wall (11) of said furnace vessel, said second electrodes (31-33) extending substantially parallel to said first electrode (21-23) and being electrically connected to said furnace lining (14).
