Abstract

Die Erfindung bezieht sich auf das Gebiet der Metallurgie. Ziel der Erfindung ist die Verhinderung des Sauens im Bereich der Windduese. Das Ziel wird dadurch erreicht, dass die Windduese zum Durchblasen mit unten eintretendem Wind aus den konzentrisch angeordneten Rohren (1, 2) besteht, die Kanaele fuer die Zufuehrung von Sauerstoff und gasfoermigem Brennstoff bilden, und einen spiralfoermigen Fuehrungsteil (3), das im Kanal zur Brennstoffzufuehrung angebracht ist, wobei die Gesamtquerschnittsflaeche der Kanaele des Fuehrungsteils (3) 0,1 bis 0,5 der Querschnittsflaeche des Sauerstoffkanals der Windduese betraegt.
