| 摘要 |
A double furnace installation having two arc furnaces connected via a line, a power supply, a device for charging material, and an arrangement for extraction and purification of gas is operated by connecting a first one of the furnaces with the power supply for melting a charge located therein, isolating a second one of the furnaces from the power supply, charging the second furnace with charging material, and closing the second furnace with a cover. Flue gas generated during a melting phase of the first furnace is sucked therefrom and introduced into the second furnace through a first interior bay region of the second furnace. The flue gas entering the second furnace in this manner passes substantially horizontally through the charging material in the second furnace because it is sucked therefrom through a second interior bay region disposed diametrically opposite the first interior bay region.
