Abstract
Description
Die Erfindung betrifft eine Anlage für die Oberflächenbehandlung eines Metallstrangs, insbesondere zum Beizen eines Stahlbandes, mit einem für den in Längsrichtung bewegten Metallstrang gebildeten Behandlungskanal und mit zur Oberfläche des Metallstranges einstellbaren Spritzdüsen, die an ein Düsenrohr für die Zufuhr der Behandlungsflüssigkeit angeschlossen sind.The invention relates to a plant for the surface treatment of a metal strand, in particular for pickling a steel strip, with one for in the longitudinal direction moving metal strand formed treatment channel and with the surface of the metal strand adjustable spray nozzles connected to a nozzle tube for the Treatment fluid supply are connected.
Eine solche Anlage ist im wesentlichen aus der DE 36 29 894 C2 bekannt, wobei der Behandlungskanal durch einen Deckel nach oben abgeschlossen ist. Der Behandlungskanal soll insofern optimiert werden, um die Beiz- bzw. Behandlungszeit weiter zu verkürzen und die Beiz- bzw. Reinigungsqualität des Behandlungsgutes zu verbessern. Dieses Ziel wird dort durch Ablaufrinnen angestrebt, denen das ein- und / oder auslaufseitig eingedüste Behandlungsmedium über eine im Zentrum des Behandlungskanals vorgesehenen Ablauf zuleitbar ist, wobei Sammelräume verbunden sind, von denen das Behandlungsmedium einem Vorratsbehälter zugeleitet wird. Such a system is essentially known from DE 36 29 894 C2, wherein the treatment channel is closed at the top by a cover. The treatment channel should be optimized to the extent of the pickling or treatment time further shorten and the pickling or cleaning quality of the material to be treated to improve. This goal is sought there through drainage channels, to which the treatment medium injected on the inlet and / or outlet side via a in the center of the treatment channel provided drain can be fed, collecting rooms are connected, of which the treatment medium is a reservoir is forwarded.
Es ist ferner eine Vorrichtung zur Oberflächenbehandlung von bandförmigem Behandlungsgut bekannt ( DE 40 31 234 C2), die einen Behandlungskanal mit Spritzdüsen aufweist, bei dem die Neigung der Spritzdüsen in Laufrichtung des Behandlungsgutes einstellbar ist. Das Behandlungsmedium wird von den Breitseiten entgegengesetzt gerichtet unter einem spitzen Winkel gegen das Behandlungsgut gefördert.It is also a device for the surface treatment of band-shaped material to be treated known (DE 40 31 234 C2), which has a treatment channel Has spray nozzles, in which the inclination of the spray nozzles in the running direction of the Good to be treated is adjustable. The treatment medium is from the broad sides oppositely directed against the material to be treated at an acute angle promoted.
Der Erfindung liegt die Aufgabe zugrunde, zum Beizen, Spülen, Reinigen oder Entfetten die kinetische Energie an den Spritzdüsen in Abhängigkeit einer Dichtwirkung am Ausgang des Behandlungskanals zu regulieren bzw. die kinetische Energie am Einlauf zu erhöhen oder reduzieren.The invention has for its object to pickling, rinsing, cleaning or Degreasing the kinetic energy at the spray nozzles depending on a sealing effect regulate at the exit of the treatment channel or the kinetic Increase or decrease energy at the inlet.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der durch eine Bodenausmauerung und Seitenwände gebildete Behandlungskanal-Querschnitt an der Oberseite mittels eines Schwimmkörpers begrenzt ist und dass die Spritzdüsen jeweils von einer nach unten auf den Metallstrang gerichteten, steilen Stellung bis in einen zwischen dem Metallstrang und dem Schwimmkörper gebildeten Behandlungskanal unter einem spitzen, flachen Winkel mit Spritzrichtung entgegen der Bewegungsrichtung des Metallstrangs einstellbar ist. Dadurch kann die kinetische Energie beim Auftreffen auf den Metallstrang reguliert werden und gleichzeitig kann eine gewisse Dichtwirkung am Ausgang des Behandlungskanals erzielt werden, wobei die Geschwindigkeit des abfließenden Behandlungsmediums beeinflusst werden kann.The object is achieved in that the by Floor lining and side walls formed treatment channel cross-section is limited at the top by means of a float and that the spray nozzles in each case from a steep position directed downwards onto the metal strand up into one formed between the metal strand and the floating body Treatment channel at an acute, flat angle with the spray direction the direction of movement of the metal strand is adjustable. This allows the kinetic energy can be regulated when hitting the metal strand and at the same time there can be a certain sealing effect at the exit of the treatment channel can be achieved, the speed of the effluent treatment medium can be influenced.
Die Strömungsverhältnisse am Eingang bzw. Ausgang des Behandlungskanals können noch dahingehend verbessert werden, dass der Schwimmkörper auf der Seite der Spritzdüsenreihe eine von oben nach unten zurückspringende Schräge bildet. The flow conditions at the entrance or exit of the treatment channel can still be improved in that the float on the On the side of the spray nozzle row, a slope that recesses from top to bottom forms.
Diese Maßnahme erlaubt nach weiteren Merkmalen, dass das Düsenrohr etwa unterhalb der schräge des Schwimmkörpers verläuft.According to further features, this measure allows the nozzle tube to be approximately runs below the slope of the float.
Die Schwenkbarkeit der Spritzdüsen, die Bestandteil des Düsenrohres sind, kann gemäß einer Ausgestaltung dadurch erreicht werden, dass das Düsenrohr über eine Drehdichtung an eine Druckleitung für die Zufuhr der Behandlungsflüssigkeit angeschlossen ist.The swiveling of the spray nozzles, which are part of the nozzle tube, can According to one embodiment can be achieved in that the nozzle tube over a rotary seal to a pressure line for the supply of the treatment liquid connected.
Sodann wird gemäß einer Weiterentwicklung die Schwenkbarkeit des Düsenrohres derart gestaltet, dass die Drehdichtung zwischen einem ersten Flansch der Druckleitung und einem zweiten Flansch eines Behälters mittels eines mittleren dritten Flansches des Düsenrohrs gebildet ist.Then, according to a further development, the pivotability of the nozzle tube designed such that the rotary seal between a first flange of the Pressure line and a second flange of a container by means of a middle third flange of the nozzle tube is formed.
Die eigentliche austauschbare Dichtung entsteht dabei dadurch, dass in dem mittleren, dritten Flansch des Düsenrohres zumindest zwei konzentrische Ringdichtungen beidseitig zu dem ersten Flansch und zu dem zweiten Flansch angeordnet sind.The actual replaceable seal is created by the fact that in the middle, third flange of the nozzle tube at least two concentric ring seals arranged on both sides of the first flange and the second flange are.
Die Dichtwirkung kann ferner dahingehend eingestellt werden, dass der erste Flansch der Druckleitung und der zweite Flansch des Behälters mittels den ersten Flansch und den zweiten Flansch verbindenden Zugelementen zueinander einstellbar sind. Bei nachlassender Dichtkraft wegen eines eintretenden Verschleißes können die Zugelemente nachjustiert werden.The sealing effect can also be adjusted so that the first Flange of the pressure line and the second flange of the container by means of the first Flange and the second flange connecting tension elements to each other adjustable are. If the sealing force decreases due to wear the tension elements can be readjusted.
Die Schwenkbarkeit des Düsenrohres erhält man nach einer Ausgestaltung, indem das Düsenrohr mittels eines verbundenen Schwenkhebels neben dem Behälter an eine Kolben-Zylinder-Einheit angelenkt und für die Schwenkbewegungen antreibbar ist. The pivotability of the nozzle tube is obtained in one embodiment by the nozzle pipe by means of a connected swivel lever next to the container hinged to a piston-cylinder unit and for the swivel movements is drivable.
Eine andere Verbesserung ergibt sich daraus, dass der Metallstrang im Bereich der schräge des Schwimmkörpers auf einem quer zur Bewegungsrichtung des Metallstrangs in die Bodenausmauerung eingelassenen Gleitstein aufstützbar ist.Another improvement stems from the fact that the metal strand is in the area the slant of the float on a cross to the direction of movement Metal strand embedded in the floor brick sliding block is supported.
Die Spritzdüsen können einzeln oder in kleineren Gruppen vorgesehen sein. Vorteilhaft ist dabei, dass an dem Düsenrohr in in Längsrichtung beabstandeten Radialebenen jeweils zwei oder mehr Spritzdüsen in einem Winkelabstand fest angeordnet sind.The spray nozzles can be provided individually or in smaller groups. Advantageous is that on the nozzle tube in the longitudinally spaced radial planes two or more spray nozzles each arranged at an angular distance are.
