Abstract

Die Erfindung liegt in einem Verfahren und einer Be­ schickungsvorrichtung für Lichtbogen-Schmelzöfen, die ei­ nen Schutz der durch Wärmestrahlung im Inneren des Licht­ bogen-Schmelzofens besonders beanspruchten Wandbe­ reiche ermöglichen, wobei verfahrensgemäß die Zu­ schlagstoffe räumlich von dem übrigen Beschichtungsmate­ rial getrennt dem Lichtbogen-Schmelzofen gezielt an den im Inneren des Schmelzofens den Elektroden am nächsten liegenden Wandbereichen zugeführt werden. Entsprechend ist die Beschickungsvorrichtung in ihrem Inneren mit min­ destens zwei Kammern ausgerüstet, jeweils mit einer obe­ ren Öffnung zum Füllen der Kammern und mit einer unteren verschließbaren Öffnung zum Entleeren der Kammern. The invention lies in a method and a loading Feeding device for arc melting furnaces, the egg Protection from heat radiation inside the light arc melting furnace particularly stressed wall enable rich, according to the procedure the Zu Impact spatially from the rest of the coating material targeted to the arc melting furnace closest to the electrodes inside the furnace lying wall areas are supplied. Corresponding is the loading device inside with min at least two chambers equipped, each with an upper ren opening for filling the chambers and with a lower one lockable opening for emptying the chambers.
