Description

Gegenstand des Patentes 81 1836 ist eine Kupolofen-Begichtungsanlage, bei der zwischen dem Kupolofen und dem Gichtaufzug ein durch die Gichtgase beheizter Vorwärmekanal mit eingebautem Transportmittel eingeschaltet ist. Dieser Vorwärmekanal kann zum Bedienen von zwei oder mehreren Kupolöfen @schwenkbar oder seitlich verstellbar angeordnet sein.The subject of patent 81 1 836 is a cupola furnace charging system in which a preheating channel heated by the furnace gases with a built-in means of transport is connected between the cupola furnace and the furnace top elevator. This preheating channel can be arranged pivotably or laterally adjustable to operate two or more cupolas.

Es hat sich als vorteilhaft erwiesen, zwischen den Kupolofen A, wie dies aus der Abbildung ersichtlich ist, und Vorwärmekanal C eine Verbrennungskammer E einzuschalten, in welcher die aufsteigenden Gichtgase nach Bedarf mit Frischluft gemischt, verbrannt «-erden. Durch Fremdzündung wird, bis eine genügend hohe Verbrennungstemperatur erreicht ist, die gleichmäßige Entzündung der C O-haltigen Gichtgase gesichert. Durch Vorschalten der Verbrennungskammer, welche gleichzeitig als Funkenfänger dient, wird das Transportmittel von der -direkten Flammeneinwirkung entlastet. Der Vorwärmekanal C wird als drehbare Trommel (s. Abbildung) ausgeführt. Diese Ausführung kommt dann in Frage, wenn ein einheitlicher, nicht gattierter Einsatz, wie Stahlschrott oder Roheisen, z. B. in Stahlwerkskupolöfen u. a. umgeschmolzen werden soll. Der Transport des Einsatzes erfolgt durch die Schräglage des Vorwärmekanals oder bei horizontaler Anordnung durch @in die Trommel eingebaute Führungszellen bzw. Führungsleisten.It has been found to be advantageous between the cupola A, such as this can be seen from the figure, and preheating duct C is a combustion chamber E to switch on, in which the rising furnace gases as required with fresh air mixed, burned "-ground. External ignition is used until a sufficiently high combustion temperature is achieved, the uniform inflammation of the CO-containing blast furnace gases is ensured. By connecting the combustion chamber, which also serves as a spark arrester, the means of transport is relieved of direct exposure to flames. The preheating channel C is designed as a rotating drum (see illustration). This execution then comes in question if a uniform, uncharged insert, such as steel scrap or Pig iron, e.g. B. in steel mill cupolas and others. is to be remelted. The transport The use takes place through the inclined position of the preheating duct or with horizontal Arrangement by means of guide cells or guide strips built into the drum.
