Description
Die Erfindung betrifft eine Sprühdüseneinrichtung insbesondere zum Besprühen eines Giessstrangs, mit einem eine diffusorartig wirkende Mischkammer aufweisenden Mischkörper, der mit einem Lufteinlass, einem Wassereinlass und einer auf der zum Lufteinlass gegenüberliegenden Seite angeordneten Düsenauslass versehen ist, durch welchen ein Luft/Wassergemisch austritt.The invention relates to a spray nozzle device, in particular for spraying a casting strand, comprising a mixing body having a diffuser-like mixing chamber, which is provided with an air inlet, a water inlet and a nozzle outlet arranged on the side opposite the air inlet, through which an air / water mixture emerges.
Sprühdüsen dieser Art werden bekanntlich zum Kühlen eines Giessstranges während des Abgiessens eingesetzt. Hierbei wird eine möglichst gleichmässige Kühlwirkung angestrebt, um zu verhindern, dass beim Kühlvorgang Risse im heissen Glessstrang entstehen können. Daher die Bemühungen, die Sprühdüse so zu konstruieren, dass der abgegebene Kühlstrahl strukturell homogen ist. Die jeweils erforderliche Kühlwirkung ist allerdings von Fall zu Fall unterschiedlich, sowohl aus verfahrenstechnischen Gründen als auch aufgrund der Abmessungen und/oder der Geometrie des abzugiessenden Formats. Dadurch sind die Einsatzbedingungen der Sprühdüse hinsichtlich des Luft- und/oder Wasserdrucks bzw. der Luft- undloder Wasserströmung variabel.Spray nozzles of this type are known to be used for cooling a casting strand during casting. In this case, the aim is to achieve as uniform a cooling effect as possible in order to prevent cracks in the hot glasstrack during the cooling process. Hence the efforts to construct the spray nozzle so that the discharged cooling jet is structurally homogeneous. However, the required cooling effect is different from case to case, both for procedural reasons as well as due to the dimensions and / or the geometry of the deducted format. Thus, the conditions of use of the spray nozzle with respect to the air and / or water pressure or the air andlor water flow are variable.
Die bisher bekannten Sprühdüsen dieser Art haben den Nachteil, dass bei ihnen beide Grössen sich im Betrieb gegenseitig beeinflussen. Das führt zu einer ungleichmässigen Beaufschlagung des Giesstrangs mit sich punktuell bildenden Wassertropfenansammlungen, die örtlich die Kühlwirkung des Sprühstrahls in unzulässigem Mass beeinträchtigen.The previously known spray nozzles of this type have the disadvantage that in both sizes affect each other in operation. This leads to an uneven loading of Gießstrangs with punctiform water droplets accumulation, locally affect the cooling effect of the spray to an inadmissible degree.
Eine Sprühdüsenanordnung dieser Art ist in der
Der Erfindung liegt die Aufgabe zugrunde, eine Sprühdüse der eingangs genannten Art zu schaffen, die einen hohen Vernebelungsgrad und eine hohe Gleichmässigkeit des Sprühstrahls unabhängig vom Giessverfahren oder Format des abzukühlenden Produktes sicherstellt. Ferner soll dies auch unabhängig von den eingestellten Mediendrücken gewährleistet sein.The invention has for its object to provide a spray nozzle of the type mentioned, which ensures a high degree of nebulization and high uniformity of the spray regardless of the casting process or format of the product to be cooled. Furthermore, this should also be ensured regardless of the set media pressures.
Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Lufteinlass einen in die Mischkammer ragenden Bereich aufweist und dort mit mindestens einer annähernd quer zur deren Längsachse gerichteten Luftaustrittsbohrung versehen ist, während der Wassereinlass durch mindestens eine nahe der Spitze des Lufteinlasses annähernd quer zur Längsachse gerichtete Bohrung erfolgt.This object is achieved according to the invention in that the air inlet has a region projecting into the mixing chamber and is provided there with at least one air outlet bore directed approximately transversely to the longitudinal axis, while the water inlet is through at least one near the tip of the air inlet approximately transverse to the longitudinal axis directed bore ,
Wie entsprechende Versuche ergeben haben, hat diese Anordnung den Vorteil, dass sich bei ihr die Luftströmung bzw. der Luftdruck und die Wasserströmung bzw, der Wasserdruck nicht in nennenswertem Masse gegenseitig beeinflussen, so dass bei verfahrenstechnisch oder formatbedingten Veränderungen dieser Grössen der von der Sprühdüse abgegebene Kühlstrahl hinsichtlich des Vernebelungsgrades und der Gleichmässigkeit des Kühlstrahls stabil bleibt.As corresponding tests have shown, this arrangement has the advantage that in her the air flow or the air pressure and the water flow or the water pressure do not influence each other to any appreciable extent, so that in procedural or format-related changes of these sizes of votes from the spray nozzle Cooling beam remains stable with respect to the degree of atomization and the uniformity of the cooling jet.
Die Erfindung sieht ferner vor, dass der Lufteinlass des Mischkörpers durch eine in die Mischkammer ragende Blende gebildet ist, die in einer Ebene quer zu deren Längsachse mit mindestens einer umfänglich verteilt angeordneten Radialaustrittsbohrungen versehen ist. Dadurch wird die Fertigung, Zusammenbau und Wartung der Sprühdüse vereinfacht.The invention further provides that the air inlet of the mixing body is formed by a diaphragm projecting into the mixing chamber, which is provided in a plane transverse to its longitudinal axis with at least one circumferentially distributed radial outlet holes. This simplifies the manufacture, assembly and maintenance of the spray nozzle.
Es ist hierbei zweckmässig, wenn der in die Mischkammer ragende Bereich der Lufteinlassdüse einen Aussendurchmesser von weniger als die Hälfte des Innendurchmessers der Mischkammer aufweist.It is expedient here if the region of the air inlet nozzle projecting into the mixing chamber has an outer diameter of less than half the inner diameter of the mixing chamber.
Es ist für die angestrebten Wirkungsweise des Mischkörpers vorteilhaft, wenn die Radialaustrittsbohrungen quer zur Längsachse der Mischkammer einen Winkel von 90° +/- max. 15° aufweisen.It is advantageous for the desired mode of action of the mixing body when the radial outlet holes transverse to the longitudinal axis of the mixing chamber an angle of 90 ° +/- max. 15 °.
Die Lufteinlassdüse kann auch zusätzlich mit einer in Achsrichtung der Mischkammer gerichteten Luftaustrittsbohrung versehen sein.The air inlet nozzle can also be provided with a directed in the axial direction of the mixing chamber air outlet bore.
Es ist auch für die Wirkungsweise der Sprühdüse von Vorteil, wenn ihre Mischkammer zylindrisch ausgebildet ist und eine Länge von vorzugsweise zweimal der Innendurchmesser aufweist.It is also for the operation of the spray nozzle advantageous if its mixing chamber is cylindrical and has a length of preferably twice the inner diameter.
Die Erfindung sieht ebenfalls vor, dass der Mischkörper einen auswechselbaren Düsenkopf mit einer Austrittsöffnung für das Luft/Wassergemisch aufweist, deren Geometrie nach dem jeweils erforderlichen Sprühbild festlegbar ist. Auf diese Weise lässt sich die Düse leicht an variable Einsatzbedingungen anpassen.The invention also provides that the mixing body has a replaceable nozzle head with an outlet opening for the air / water mixture, the geometry of which can be fixed according to the respectively required spray pattern. In this way, the nozzle can be easily adapted to variable operating conditions.

Die Sprühdüseneinrichtung gemäss
Die Mischkammer 2 des Mischkörpers 1 ist zylindrisch ausgebildet. Ihre Länge beträgt ca. zweimal der Innendurchmesser der Mischkammer. Der Lufteinlass 3 ist in einer Lufteinlassdüse 6 angeordnet, deren Spitze 7 in den oberen Bereich der Mischkammer hineinragt. Die Lufteinlassdüse 6 ist koaxial zur Mischkammer 2 ausgerichtet, und ihr Aussendurchmesser ist dort kleiner als der halbe Innendurchmesser der Mischkammer. In diesem Bereich ist sie mit von dieser annähernd quer zur Längsachse der Mischkammer radial ausgehenden Luftaustrittsbohrungen 9 versehen, die umfänglich in einer Ebene quer zur Längsachse gleichmässig verteilt sind.The
Der Wassereinlass 4 mündet in die Mischkammer 2 nahe der Spitze 7 des Lufteinlasses 3 mit einer quer zu deren Längsachse gerichteten Wasseraustrittsbohrung 11, deren Abstand zur Spitze 7 so bemessen ist, dass der aus ihr strömende Wasserstrahl die Luftaustrittsbohrungen 9 nicht tangiert. Die beschriebene Sprühdüse ist mit nur einer Wasseraustrittsbohrung ausgestattet. Sie kann im Prinzip aber auch mit mehreren umfänglich verteilt angeordneten Wasseraustrittsbohrungen versehen sein.The
Der Wassereinlass 4 ist durch eine annähernd parallel zur Längsachse des Mischkörpers 1 verlaufenden Bohrung 11' und durch diese quere Wasseraustrittsbohrung 11 gebildet. In der Bohrung 11' ist eingangs ein auswechselbarer Filter 19 und nachfolgend eine Blende 4' enthalten und zudem ist sie mit einer Überbohrung 11" versehen, die als Verlängerung ausgehend von der queren Wasseraustrittsbohrung 11 ausgebildet ist und für eine Beruhigung des in die Wasseraustrittsbohrung 11 geleiteten Wassers dient.The
Ferner sind die radialen Luftaustrittsbohrungen 9 mit einem leichten Winkel zur senkrechten Ebene ausgeführt, wobei der Neigungswinkel in einem Bereich von +/- max. 15° variieren kann. Darüberhinaus könnten sie auch statt radial zumindest annähernd tangential ausgerichtet sein, wodurch eine Verwirbelung des in die Mischkammer strömenden Wasserstrahls erzeugt wird, die eine gleichmässig feinstrukturierte Vernebelung des Luft/Wassergemisches mit sich bringt.Furthermore, the radial
Der zylindrisch ausgebildete Mischkörper 1 weist in Verlängerung der Mischkammer 2 einen ebenfalls zylindrischen Ansatz 14 auf, an dessen Ende ein auswechselbarer Düsenkopf 15 mit einer Luft/Wassergemisch-Austrittsöffnung 16 angebracht ist. Die Verbindung des Düsenkopfes 15 am Mischkörper 1 ist im Ansatz 14 des Mischkörpers angeordnet.The cylindrically shaped
Statt einer solchen einwandfrei funktionierenden Schraubverbindung könnte auch ein Bajonettverschluss oder eine ähnlich lösbare Verbindung verwendbar. Durch die Auswechselbarkeit des Düsenkopfes 15 kann das Sprühbild der Düse je nach Form der einen oder mehreren Austrittsöffnungen von Fall zu Fall leicht den jeweiligen Einsatzbedingungen angepasst werden.Instead of such a properly functioning screw and a bayonet closure or a similar detachable connection could be used. Due to the interchangeability of the
Gemäss
Beim Lufteinlass 3 und Wassereinlass 4 ist jeweils eine Blende 4' zur Drosselung der zugeführten Luft bzw. des Wassers vorgesehen.In the case of the
Die Vorteile der erfindungsgemässen Sprühdüse gelten selbstverständlich auch, wenn als Kühlmittel anstelle des Luft/Wassergemisches ein anderes vergleichbar geartetes Gas/Flüssigkeitsgemisch eingesetzt wird.Of course, the advantages of the spray nozzle according to the invention also apply if, as a coolant, another gas / liquid mixture of comparable type is used instead of the air / water mixture.
Sowohl die Luftaustrittsbohrungen als auch die Wassersaustrittsbohrungen können statt radial zumindest annähernd tangential ausgerichtet sein.Both the air outlet holes and the water outlet holes can be aligned instead of radially at least approximately tangentially.
Es könnte auch ein Verlängerungsrohr zwischen dem Mischkörper 1 und dem Düsenauslass 5 vorgesehen sein, wenn beispielsweise kleinere Formate von Strängen gegossen werden.An extension tube could also be provided between the mixing
Bei einem Betriebsunterbruch oder Giessstopp könnte auch nur Luft durch die Sprühdüseneinrichtung zugeführt werden, um eine ausreichende Kühlung derselben zu gewährleisten.In the event of a stoppage or cessation of casting, only air could be supplied through the spray nozzle device in order to ensure sufficient cooling thereof.
Zum Ermitteln der Sprühleistung der Düse wurden Versuche mit variablen Druck- und Strömungswerten durchgeführt. Wie aus dem Diagramm gemäss
Bei den Versuchen wurden folgende Druck- und Strömungswerte festgestellt:
Aus der Tabelle ist zu entnehmen, dass der Kurvenverlauf 1B-2B der Wasserströmung bei Steigerung des Luftdrucks von 2 auf 3 bar bzw. bei Anhebung der Luftströmung von 6,0 auf 7,8 m3/h konstant bleibt. Die erfindungsgemässe Sprühdüse gewährleistet damit eine gleichmässig homogene Beschaffenheit des Luft/Wassergemisches, unabhängig der jeweils geforderten Kühlwirkung. Es besteht somit eine gegenseitige Unabhängigkeit Ober einen grossen Druckbereich des Luft- bzw. Wasserdruckes.From the table it can be seen that the
