Description
Die Erfindung betrifft eine Vorrichtung zum schwebenden Führen von metallischen Bändern mittels eines Gases mit einer Mehrzahl von Wärmebehandlungseinheiten mit jeweilseinem unteren und oberen Düsenherd, einem unteren und oberen Strömungskanalsystem, wenigstens einem Ventilator und mehreren Strahlrohren wobei jedes Strömungskanalsystem quer zur Bandrichtung wenigstens eine Vertiefung in Richtung der Düsenherde zur Aufnahme wenigstens eines Strahlrohres aufweist sowie ein Verfahren zum Betreiben einer solchen Vorrichtung.The invention relates to a device for the floating guiding of metal strips by means of a gas having a plurality of heat treatment units each having a lower and upper nozzle hearth, a lower and upper flow channel system, at least one fan and a plurality of jet pipes, wherein each flow channel system at least one depression in the direction of the belt direction Having nozzle herd for receiving at least one jet pipe and a method for operating such a device.
Vorrichtungen zum schwebenden Führen von metallischen Bändern dienen dazu, breitere Metallbänder durch Beaufschlagung mit Gas von oben und unten in der Schwebe zu halten und zur gleichzeitigen Temperierung. Als Gas kann, je nach Anwendung, Schutzgas oder auch Luft zum Einsatz kommen. Die Temperierung kann sowohl die Erwärmung auf Glühtemperatur und Halten dieser Temperatur mit einem anschließenden Abkühlen aus metallurgischen Gründen beinhalten als auch zum Zweck der reinen Oberflächenbehandlung der Bänder, wie beispielsweise der Trocknung von beschichteten Bändern, erfolgen.Devices for floatingly guiding metallic strips serve to hold wider metal strips suspended from above and below by the application of gas and for simultaneous tempering. Depending on the application, inert gas or even air can be used as the gas. The tempering may include both heating to annealing temperature and maintaining that temperature followed by cooling for metallurgical reasons, as well as for the purpose of pure surface treatment of the ribbons, such as drying coated ribbons.
Dabei wird das strahlrohrerwärmte Gas mittels der Ventilatoren angesaugt und den unteren und oberen Strömungskanalsystemen zugeführt, welche das Gas durch untere und obere Düsenherde in Richtung auf das Metallband laden, das dadurch in der Schwebe gehalten wird. Die Anpassung an das Bandgewicht wird durch Auslegung der verwendeten Ventilatoren bzw. deren Drehzahlen bestimmt.In this case, the radiant tube-heated gas is sucked by means of the fans and supplied to the lower and upper flow channel systems, which load the gas through the lower and upper nozzle stoves in the direction of the metal strip, which is thereby held in suspension. The adaptation to the band weight is determined by the design of the fans used or their speeds.

Die auf die Anmelderin der vorliegenden Patentanmeldung zurückgehende
Eine andere gattungsgemäße Vorrichtung ist in der
Vor diesem Hintergrund liegt der vorliegenden Erfindung die Aufgabe zu Grunde, die eingangs genannte und zuvor näher beschriebene Vorrichtung und ein entsprechendes Verfahren zum Betreiben einer solchen Vorrichtung so auszugestalten und weiterzubilden, dass die Energieeffizienz, die Wärmeübertragung und damit die Durchsatzleistung sowie die Produktqualität der Vorrichtung verbessert wird. Darüber hinaus ist es erwünscht, die Vorrichtung für die Wartungs- und Instandhaltungsmaßnahmen zu optimieren. Insbesondere sollen auch Bänder von unterschiedlicher Breite bzw. Stärke und damit unterschiedlichem Gewichts von der Vorrichtung verwendet werden können.Against this background, the object of the present invention is to design and further develop the device described above and described in greater detail and a corresponding method for operating such a device, that improves the energy efficiency, the heat transfer and thus the throughput and the product quality of the device becomes. In addition, it is desirable to optimize the device for maintenance and servicing. In particular, also bands of different width or thickness and thus different weights should be used by the device.
Dazu ist bei einer Vorrichtung nach dem Oberbegriff von Anspruch 1 zur Lösung der Aufgabe vorgesehen, dass die Vertiefung jedes Strömungskanalsystems im Längsschnitt Bogen- oder parabelförmig ausgebildet ist. Hierbei werden bevorzugt große Radien verwendet und notwendige Leitbleche und Versteifungsbleche verleihen der Konstruktion eine hohe Stabilität. Die gebogene Vertiefung sorgt auch für eine „sanfte” Umlenkung und Führung der Strömung und minimiert daher Strömungsverluste.For this purpose, in a device according to the preamble of
Verfahrensmäßig erfolgt die Lösung der Aufgabe dadurch, dass der Druck- und Volumenstrom und/oder Temperatur des unteren Düsenherdes unabhängig vom oberen Düsenherd geregelt werden kann.In terms of method, the object is achieved in that the pressure and flow rate and / or temperature of the lower nozzle hearth can be controlled independently of the upper nozzle hearth.
Die gebogene Vertiefung des Druckraumes wurde gewählt, um ein oder mehrere Strahlrohr/e aufnehmen zu können, die sich auf diese Weise im strömungsaktiven Teil des Saugraumes, längs in Strömungsrichtung positioniert anordnen lassen. Sie sind an einer Seite der Wärmebehandlungseinheit befestigt und auf der anderen Seite auf einer stabilen Stütze bzw. auf stabilen Aufhängungen abgelegt, die eine freie Wärmeausdehnung über ein Abrollgelenk erlauben.The curved depression of the pressure chamber has been selected in order to be able to receive one or more jet tubes, which can be arranged in this way in the flow-active part of the suction chamber, positioned longitudinally in the flow direction. They are attached to one side of the heat treatment unit and placed on the other side on a stable support or on stable suspensions that allow free thermal expansion via a unwinding.
Aufgrund dieser Geometrie des Saugraumes können die Ventilatoren über die gesamte Strahlrohrlänge frei ansaugen. Die in der Vertiefung des Druckraums im dadurch vergrößerten Saugraum angeordneten Strahlrohre bestrahlen die Strömungskanalsysteme gleichmäßig, so dass eine bessere Wärme- und Spannungsverteilung erreicht und der Wärmeübergang durch Konvektion wesentlich verbessert wird. Bedingt durch die spezielle Form und Symmetrie des erfindungsgemäßen Strömungskanalsystems hat dieser eine hohe Eigenstabilität.Due to this geometry of the suction chamber, the fans can suck in freely over the entire length of the jet pipe. The jet pipes arranged in the recess of the pressure chamber in the enlarged suction space thereby enlarged uniformly irradiate the flow channel systems, so that a better heat and stress distribution is achieved and the heat transfer by convection is substantially improved. Due to the special shape and Symmetry of the flow channel system according to the invention this has a high intrinsic stability.
Der Druckraum „umschließt” die Strahlrohre im Saugraum, so dass die Wärme effektiver übertragen werden kann. Dies erfolgt insbesondere durch die bogen- oder parabelförmige Vertiefung, die die Strahlung von den Strahlrohren im Saugraum annimmt und sie gleichmäßig im Druckraum verteilt und weitergibt. Zudem wird durch die gebogene Vertiefung die Wärme wieder abgestrahlt und auf die konzentrierte Strömung im Saugraum fokussiert. Da die gebogene Vertiefung eine größere Fläche als ein durchgehend rechteckiger Kanal aufweist, findet hier ein intensiverer Wärmeübergang durch Konvektion statt. Neben einer bogen- oder parabelförmigen Vertiefung ist es im Rahmen der Erfindung auch möglich, die Vertiefung U-förmig auszubilden.The pressure chamber "encloses" the jet pipes in the suction chamber, so that the heat can be transmitted more effectively. This is done in particular by the arcuate or parabolic depression, which accepts the radiation from the jet tubes in the suction chamber and distributes them evenly in the pressure chamber and passes them on. In addition, the heat is radiated through the curved depression and focused on the concentrated flow in the suction chamber. Since the curved recess has a larger area than a continuous rectangular channel, a more intense heat transfer by convection takes place here. In addition to a curved or parabolic depression, it is also possible within the scope of the invention to form the depression in a U-shape.
Auch die Spannungen im Material des Strömungskanalsystems durch Eigengewicht und Wärmebelastung verteilen sich gleichmäßig, so dass die Lebensdauer der verwendeten Bauteile signifikant erhöht werden konnte.The stresses in the material of the flow channel system by weight and heat load are distributed evenly, so that the life of the components used could be significantly increased.
Eine weitere, bevorzugte Lehre der Erfindung sieht vor, dass jedes Strömungskanalsystem einer Wärmebehandlungseinheit drei untere und drei obere Strahlrohre aufweist, die so angeordnet sind, dass sie der Geometrie der Vertiefung angepasst sind. Bei der Verwendung von drei Strahlrohren lässt sich das mittlere Strahlrohr an der tiefsten Stelle der Vertiefung anordnen, um einen besonders guten Wärmeübergang zu gewährleisten.A further, preferred teaching of the invention provides that each flow channel system of a heat treatment unit has three lower and three upper jet tubes, which are arranged so that they are adapted to the geometry of the depression. When using three radiant tubes, the central jet tube can be arranged at the lowest point of the depression in order to ensure particularly good heat transfer.
In weitere Ausgestaltung der Erfindung ist vorgesehen, dass jedes Strömungskanalsystem einen Ventilator, vorzugweise Radialventilator, zwei seitliche Druckkanäle und einen gemeinsamen Druckraum mit zwei äußeren Leitkanälen aufweist und dass die Druckkanäle in die Leitkanäle münden. Dies führt zu einer besonders kompakten Konstruktion und – verglichen mit dem Stand der Technik – zu einer signifikanten Verkürzung der Strömungsstrecke des Gases. Die kurze Strömungsstrecke und auch die Geometrie der Kanäle bewirken eine bessere Strömungs-, Druck- und Wärmeverteilung, so dass sich auch die Druckverluste durch Reibung und Verwirbelungen deutlich reduzieren.In a further embodiment of the invention, it is provided that each flow channel system has a fan, preferably a radial fan, two lateral pressure channels and a common pressure chamber with two outer guide channels and that the pressure channels open into the guide channels. This leads to a particularly compact construction and - compared to the prior art - to a significant shortening of the flow path of the gas. The short flow path and the geometry of the channels cause a better flow, pressure and heat distribution, so that the pressure losses due to friction and turbulence significantly reduced.
Eine weitere Lehre der Erfindung sieht vor, dass zwischen den Druckkanälen und Leitkanälen Ausdehnungskompensatoren angeordnet sind. Da bei der beschrieben Konstruktion die Druckkanäle der Ventilatoren beidseitig unmittelbar in die Leitkanäle des Druckraumes münden, sind je Strömungskanalsystem nur zwei Kompensatoren notwendig, so dass auch die Anzahl möglicher Leckagestellen minimiert ist.Another teaching of the invention provides that expansion compensators are arranged between the pressure channels and guide channels. Since in the construction described, the pressure channels of the fans open on both sides directly into the guide channels of the pressure chamber, only two compensators are necessary per flow channel system, so that the number of possible leakage points is minimized.
In einer bevorzugten Ausbildung der Erfindung sind die Ventilatoren unterschiedlich groß ausgeführt, wobei die Dimensionierung des unteren Ventilators größer gewählt wird als die des oberen Ventilators, um die Gewichtskraft des Metallbandes besser aufnehmen zu können. Bei einer solchen Wärmebehandlungseinheit erfolgt ein spiegelsymmetrischer Aufbau mit einer vertikalen Spiegelachse quer zur Bandlaufrichtung.In a preferred embodiment of the invention, the fans are designed differently sized, the dimensioning of the lower fan is chosen to be greater than that of the upper fan in order to better absorb the weight of the metal strip can. In such a heat treatment unit is a mirror-symmetrical structure with a vertical mirror axis transverse to the direction of tape travel.
Eine alternative Ausführung sieht vor, dass die Ventilatoren gleich groß ausgeführt sind. Dies führt dazu, dass jede Wärmebehandlungseinheit nicht nur vertikal sondern auch horizontal spiegelsymmetrisch aufgebaut ist, was unmittelbar zu einer drastischen Reduzierung der verwendeten Konstruktionsteile führt.An alternative embodiment provides that the fans are made the same size. As a result, each heat treatment unit is constructed not only vertically but also horizontally in a mirror-symmetrical manner, which leads directly to a drastic reduction of the construction parts used.
Nach einer weiteren Lehre der Erfindung ist jede Wärmebehandlungseinheit in einem wärmeisolierten Gehäuse angeordnet, um die Wärmeverluste so gut wie möglich zu reduzieren.According to another teaching of the invention, each heat treatment unit is arranged in a heat-insulated housing in order to reduce the heat losses as well as possible.
Schließlich ist vorgesehen, dass im Ansaugbereich jedes Ventilators Sperrbleche mit verstellbaren Öffnungen vorgesehen sind, die die Gasströmung im Strahlrohrbereich konzentriert und beschleunigt, um so zu bestimmten, wieviel an Volumenstrom an den Strahlrohren vorbei gehen soll. Durch eine permanente und intensive Umströmung der Strahlrohre in Längsrichtung wird mehr Wärme konvektiv übertragen und die thermische Belastung der Strahlrohre sowie des sie umgebenden Druckraumgehäuses durch Wärmestau reduziert.Finally, it is provided that in the intake of each fan locking plates are provided with adjustable openings, which concentrates and accelerates the flow of gas in the jet pipe area, so as to determine how much volume flow to go to the jet pipes over. By a permanent and intensive flow around the jet pipes in the longitudinal direction more heat is transferred convectively and reduces the thermal load of the jet pipes and the surrounding pressure chamber housing by heat accumulation.
