Abstract

In a nozzle tube for an oxygen-blown converter, the nozzle passes inert gas regulated by shaped incorporated obstacles. The nozzle tube may be extremely long with an extremely small flow cross-section in relation to its dia. and may be used for passage of any gases or liqs. and may comprise bottom-blowing nozzles or nozzles fitted in any shape, position and arrangement.

Description

Stand der TechnikState of the art

Bekannt sind Schlitz-, Rohr-, Poren-, Lamellen- und sonstige dem Stand der Technik entsprechende Düsen. (Fundstellen: Zeitschriften des VDEh).Slit, tube, pore, lamella and other are known state of the art nozzles. (Locations: VDEh magazines).

Der Nachteil der bekannten Düsen ist, daß die Düsen z. T. nicht in den gewünschten Längen hergestellt werden können und zu große Gasdurchflußmengen zur Überwindung des ferrostatischen Druckes des flüssigen Stahles benötigt werden.The disadvantage of the known nozzles is that the nozzles z. T. cannot be produced in the desired lengths and Excessive gas flow rates to overcome the ferrostatic Pressure of the molten steel.

Problemproblem

Der in den Patentansprüchen 1 bis 4 angegebenen Erfindung nebst Varianten liegt das Problem zugrunde, daß einerseits zu hoher Gas- bzw. Flüssigkeitsverbrauch kostenungünstig ist und andererseits die bisher bekannten Düsen nur mit hohem handwerklichem Aufwand hergestellt werden können.The invention specified in claims 1 to 4 besides variants, the problem is based on the one hand that high gas or liquid consumption is inexpensive and on the other hand, the previously known nozzles only with a high level of craftsmanship Effort can be produced.

Lösungsolution

Diese Probleme werden durch die in den Patentansprüchen 1 bis 4 aufgeführten Merkmale gelöst.These problems are solved by the in claims 1 to 4 listed features solved.

Erreichte VorteileAchieved advantages

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Herstellung der Düse vereinfacht ist und dabei von ihrer Nutzungsanwendung her rohstoffsparende (Gase bzw. Flüssigkeiten) Auswirkungen mit sich bringt.The advantages achieved with the invention are in particular in that the manufacture of the nozzle is simplified and Thereby, raw material-saving (gases or liquids) has effects.

Beschreibung von AusführungsbeispielenDescription of exemplary embodiments

Die Beispiels-Zeichnungen unterscheiden zwischen 5 Varianten:The example drawings distinguish between 5 variants:

Fig. 1 zeigt ein Drahtbündelrohr; d. h. ein Rohr, welches mit gebündelten Drähten gefüllt ist, die durch z. B. Pressen, Klammern, Verkleben, Verschmelzen oder andere dem Stand der Technik entsprechende Befestigungsverfahren verbunden sind. Fig. 1 shows a wire bundle tube; ie a tube which is filled with bundled wires which by z. B. pressing, staples, gluing, fusing or other fastening methods corresponding to the prior art.

Fig. 2 zeigt ein Drahtbündelrohr in Abwandlung zu Fig. 1, in welchem die eingebrachten Drähte beliebig unterschiedliche Querschnitte haben können. Die Seele besteht aus Vollmaterial (Fig. 2a) oder Rohr (Fig. 2b) mit frei wählbarer Wandstärke. Fig. 2 shows a wire bundle tube in a modification of Fig. 1, in which the wires introduced can have any cross-section. The core consists of solid material ( Fig. 2a) or tube ( Fig. 2b) with freely selectable wall thickness.

Fig. 3 zeigt ein Düsenrohr in Abwandlung bzw. Ergänzung zu den Fig. 1 und 2, bei dem die Form der Düse selbst sowie die einbringbaren Hindernisse in beliebigen Rohr- oder Stabformen, beliebigen Materialien in symmetrischen und asymmetrischen Formen gewählt werden können. Fig. 3 shows a nozzle tube in a modification or addition to FIGS. 1 and 2, in which the shape of the nozzle itself and the obstacles that can be introduced can be selected in any tube or rod shape, any materials in symmetrical and asymmetrical shapes.

Fig. 4 zeigt ein Düsenrohr mit einem Einsatz in spiralenförmiger Ausführung. Fig. 4 shows a nozzle tube with a spiral-shaped insert.
