摘要 |
The arc furnace supplying device has a rectifier (1) whose alternating current side is connected with an electrical alternating current network (2). An inverter (4) is formed to apply a rectangular alternating current to the arc furnace electrode (5). The frequency of the rectangular alternating current corresponds to the frequency of the alternating current of the electrical alternating current network. An independent claim is also included for the electric arc furnace having electric arc furnace supplying device. |
