METHOD FOR OPERATING AN ELECTRIC ARC FURNACE AND ELECTRIC ARC FURNACE |
| 摘要 |
An electric arc furnace (2) and to a method for operating an electric arc furnace having at least one electrode (4a, 4b, 4c) for generating an electric arc (6a, 6b, 6c), in which the desired value of the current (I) guided to the electrode (4a, 4b, 4c) oscillates about a predetermined base value (I0). |

1. A method for operating an electric arc furnace comprising a furnace vessel for metal to be melted and having at least one electrode for generating an electric arc extending into the vessel;
an electric current supply to each of the electrodes, which supply is variable over time by at least one of variations of electric current and variations of frequency; and the method comprising oscillating of a target value of current fed to the electrode about a pre-determined base value (I0). |
