Verfahren und Einrichtung zum Betreiben einer Zweiofenanlage

摘要

The invention relates to a steel works installation with a double-furnace plant and to a process for operating this installation. The process is intended for melting steel in an energy-saving manner without pollution of the environment. For this purpose, it is characterised by the following steps: one of the two furnaces is supplied with electric power for melting the charge present therein and the other is completely separated from the mains; the furnace which has been taken off from the power mains and tapped is charged with charge material; the furnace vessel is then sealed by a cover; subsequently the gas present in the vessel space is extracted above the column of charge; the flue gas from the furnace in electric operation is extracted from the furnace separated from the power mains via a connecting line provided between the two furnaces, the flue gas connection of the other furnace to the gas purification being broken during the extraction of the flue gas from the furnace separated from the power mains; and at the same time added air is taken up in the region of the cover of the furnace which is in electric operation. This double-furnace installation is designed according to the invention in a special manner.
