Description
Windfrischverfahren zur Erzeugung von Flußeisen und Stahl Es ist bei Frischverfahren in der Birne bekannt: z. bei der Kleinbirne, bei der von unten Wind überhaupt nicht zugeführt wird, neben der üblichen eine zweite Düsenreihe anzuordnen, z. durch `die Winddüsen Zuschläge einzuführen, 3. durch besondere, seitlich und in der Nähe des Bodens angeordnete Öffnungen Zuschläge dem Bade zuzuführen, q.. besondere, seitlich und in der Nähe des Bodens angeordnete Düsen an die Luftzuführung anzuschließen, welche die Bodendüsen speist, und durch diese seitlichen Düsen Zuschläge in das Bad gelangen zu lassen, 5. dem für die Durchführung des Unterwindfrischverfahrens eingerichteten Frischgefäß eine von diesem getrennte Einbla.svorrichtung zuzuordnen zwecks Einblasens von Luft oder brennbarer Gase oder eines Luft-und Gasgemisches von oben in das Frischgefäß.Wind freshening process for the production of fluoro iron and steel It is at Fresh process in the pear known: z. with the small pear, with the wind from below is not fed at all, to arrange a second row of nozzles next to the usual one, z. by introducing surcharges through the tuyeres, 3. by special, lateral and Openings arranged near the bottom to feed aggregates into the bath, q .. special nozzles on the side and near the floor for the air supply to be connected, which feeds the bottom nozzles, and supplements through these side nozzles to get into the bath, 5. that for carrying out the under-wind freshening process assigned fresh vessel set up a separate blowing device from this for the purpose of blowing in air or flammable gases or an air and gas mixture from above into the fresh vessel.
Es wurde nun gefunden, daß zwecks Erhöhung der Temperatur des Bades und rascher Bildung einer leichtflüssigen Schlacke gleichzeitig von unten und dicht unterhalb der Oberfläche des Metallbades von der Seite Wind durch das Bad eingeführt wird. Hierdurch wird erreicht, daß eine möglichst rasche Oxydation und eine möglichst rasche Berührung der im Bade gebildeten Oxydationserzeugnisse mit der auf dem Metallbade ruhenden Kalk- bzw. Schlackendecke herbeigeführt wird. Durch die stärkere Verbrennung in der Nähe des Kalkzuschlages erfolgt eine raschere Erwärmung und Flüssigmachung des Kalkes, die- noch besonders durch die im Metallbad in der Nähe des Kalkes gebildeten, als Schmelzmittel wirkenden Oxyde gefördert wird.It has now been found that in order to increase the temperature of the bath and rapid formation of a light slag simultaneously from below and from below below the surface of the metal bath from the side wind introduced through the bath will. This ensures that oxidation is as rapid as possible and as possible rapid contact of the oxidation products formed in the bath with that on the metal bath static lime or slag cover is brought about. Because of the stronger combustion in the vicinity of the lime aggregate there is more rapid heating and liquefaction of the lime, which - especially due to those formed in the metal bath near the lime, Oxide acting as a flux is promoted.
Als technischer Erfolg ergibt sich eine Verbesserung - des Prozesses und eine bessere Wärmebilanz.As a technical success there is an improvement - the process and a better heat balance.
