Claims (1)

<Desc/Clms Page number 3> vergierend-divergierenden Teil, wobei vorzugsweise der Halsteil oder der divergierende Teil zwecks Erzielung eines zusammengefassten, tief eindringenden Strahles sehr lang ausgeführt ist, aufweist, dadurch gekennzeichnet, dass man, sobald eine Verbreiterung des Gasstrahles erwünscht ist, ihn mittels einer Anzahl von Sekundärgasstrahlen stört, deren Einführung in den Hauptstrahl in der Höhe des divergierenden Teiles der Lanze erfolgt. <Desc / Clms Page number 3> The verging-diverging part, wherein the neck part or the diverging part is preferably made very long in order to achieve a combined, deeply penetrating jet, characterized in that, as soon as a broadening of the gas jet is desired, it is disturbed by means of a number of secondary gas jets, whose introduction into the main beam takes place at the level of the diverging part of the lance. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass das Sekundärblasgas von jenem des Hauptstrahles verschieden ist. 2. The method according to claim 1, characterized in that the secondary blowing gas is different from that of the main jet. 3. Vorrichtung zur Durchführung des Verfahrens nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Blaslanze zwei konzentrische Leitungen aufweist, deren äussere, am unteren Ende geschlossene Leitung Gas durch Querkanäle in die Zentralleitung in solcher Weise abgibt, dass das durch diese Querkanäle durchtretende Gas den Zentralstrahl durchstösst und ihn verbreitert. 3. Apparatus for performing the method according to claim 1 or 2, characterized in that the lance has two concentric lines, the outer, closed at the lower end of the line releases gas through transverse channels into the central line in such a way that the gas passing through these transverse channels pierces the central ray and widens it. 4. Vorrichtung nach Anspruch 3, dadurch gekennzeichnet, dass die die periphere Leitung mit der Hauptleitung verbindenden Querkanäle in der Höhe des divergierenden Teiles der Zentraldüse angeordnet sind. 4. Apparatus according to claim 3, characterized in that the transverse channels connecting the peripheral line to the main line are arranged at the level of the diverging part of the central nozzle. 5. Vorrichtung nach Anspruch 3 oder 4, dadurch gekennzeichnet, dass die Querkanäle eine konvergierend-divergierende Form aufweisen. 5. Apparatus according to claim 3 or 4, characterized in that the transverse channels have a converging-diverging shape. 6. Vorrichtung nach den Ansprüchen 3 bis 5, dadurch gekennzeichnet, dass die Querkanäle in solcher Weise angeordnet sind, dass die Achsen der Sekundärstrahlen mit der Achse des Hauptstrahles im Sinne der Strömungsrichtung des Hauptstrahles einen spitzen Winkel, vorzugsweise von weniger als 700, bilden. 6. Device according to claims 3 to 5, characterized in that the transverse channels are arranged in such a way that the axes of the secondary jets form an acute angle, preferably less than 700, with the axis of the main jet in the sense of the direction of flow of the main jet. 7. Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, dass die Achsen der Sekundärstrahlen in einem Punkt der Achse der Zentraldüse zusammenlaufen. 7. Apparatus according to claim 6, characterized in that the axes of the secondary jets converge at a point on the axis of the central nozzle. 8. Vorrichtung nach Anspruch 6, dadurch gekennzeichnet, dass die Achsen der Querkanäle derart verlaufen, dass die Sekundärstrahlen tangential zum Hauptstrahl verlaufen. 8. The device according to claim 6, characterized in that the axes of the transverse channels run such that the secondary beams are tangential to the main beam.
