Abstract

Ein Elektrolichtbogenofen mit einem Untergefäß (2) und einem Obergefäß (3), das im Betrieb mittels eines Ofendeckels (4) abgeschlossen ist, ferner mit einem Abgaskrümmer (5), der über ein für die Luftzuführung zwecks Nachverbrennung der Ofengase im Abstand (13) einstellbares Klappstück (6) oder eine Schiebemuffe mit einer Brennkammer (7) oder einer stationären Abgasleitung in Verbindung steht, löst die Aufgabe, bei kontrollierter Führung der Luftmengen im Bereich der Elektroden eine gleichmäßigere Wärmeverteilung im Ofen zu erzielen, dadurch, dass der Abgaskrümmer (5) auf der Seite des Ofengefäßes (1) als sich zur Ansaug-öffnung (5b) hin verbreiternde Abgashaube (5a) ausgebildet und das Deckelloch (4a) um die Elektrode (10) oder die Elektroden (10) abdeckend ausgebildet ist.

Figure 00000001
An electric arc furnace with a lower vessel (2) and an upper vessel (3), which is closed during operation by means of an oven lid (4), furthermore with an exhaust manifold (5), which is at a distance (13) for the air supply for post-combustion of the furnace gases. adjustable folding piece (6) or a sliding sleeve is connected to a combustion chamber (7) or a stationary flue gas pipe, solves the task of achieving a more uniform heat distribution in the furnace with controlled flow of air in the area of the electrodes, in that the exhaust manifold (5 ) on the side of the furnace vessel (1) as an exhaust hood (5a) widening towards the suction opening (5b) and the cover hole (4a) around the electrode (10) or the electrodes (10) is designed to cover.
