Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Behandlung von metallischem Stranggut, insbesondere zum Beizen von Walzband, das durch einen Behandlungskana transportierbar und mit Behandlungsflüssigkeit aus Düsen turbulent bestrahlbar ist, wobei die Flüssigkeitsstrahlen am Kanaleingang in Strangtransportrichtung eingestellt sind und am Kanalausgang entgegengesetzt zur Strangtransportrichtung gerichtet sind, um ein schnelles Abfließen der Behandlungsflüssigkeit zu hemmen.The invention relates to a device for treating metallic extrudates, in particular for pickling rolled strip that can be transported through a treatment channel and can be turbulently irradiated with treatment liquid from nozzles, wherein the liquid jets at the channel entrance are set in the strand transport direction and at the channel exit are opposite to the strand transport direction, to prevent the treatment liquid from draining off quickly.
Eine derartige Vorrichtung ist aus der DE-OS 29 11 701 bekannt. Diese Bauweise strebt an, die Schwierigkeiten beim Einsatz von Quetschrollen und damit eine Übertragung von Behandlungsflüssigkeit zwischen einzelnen Tanks zu vermeiden. Dabei sollen Stütz- oder Führungswalzen durch andere Elemente ersetzt werden. Zum einen geht diese Bauweise von länglich rechteckigen Behandlungskammern aus und zum anderen sind parallel und senkrecht zur Strangtransportrichtung Behandlungsdüsen angeordnet. Zusätzlich zu den Behandlungsdüsen sind sog. Deflektoren über und unter dem Stranggut angeordnet, die eine bessere Besprühung des Stranggutes bewirken sollen. Die aufgezeigten Maßnahmen richten sich jedoch ausschließlich auf eine weitere Verwirbelung und Steigerung der Turbulenz und stellen rein mechanische Vorgehensweisen dar. Eine weitergehende chemische Wirkung ist weder vorgesehen noch beabsichtigt. Such a device is known from DE-OS 29 11 701. This design aims at the difficulties with the use of pinch rollers and thus a transfer to avoid treatment liquid between individual tanks. there support or guide rollers are to be replaced by other elements. On the one hand this construction is based on elongated rectangular treatment chambers and on the other hand, treatment nozzles are parallel and perpendicular to the strand transport direction arranged. In addition to the treatment nozzles, so-called deflectors are over and arranged under the strand material, which is a better spraying of the strand material should effect. However, the measures outlined are exclusively aimed at a further turbulence and turbulence and represent purely mechanical Procedures. A further chemical effect is not intended still intended.
Der Erfindung liegt die Aufgabe zugrunde, neben den physikalischen Wirkungen der Turbulenz die chemischen Wirkungen der Behandlungsflüssigkeit und ggfs. sogar schon den Oberflächenzustand des Stranggutes zu verbessern im Sinn einer Durchsatzerhöhung und der Ausdehnung der Behandlung auf kritische Stahlsorten.The invention is based, in addition to the physical effects of the task Turbulence the chemical effects of the treatment liquid and possibly even to improve the surface condition of the strand material in the sense of increasing the throughput and extending treatment to critical steel grades.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Behandlungskanal an der Oberseite mittels aneinandergereihten Schwimmkörpern gebildet ist, die dem Stranggut zugewandt, jeweils mit einzelnen oder mehreren, flächenverteilten Wärmetauschern versehen sind, deren Wärmeenergie auf die Behandlungsflüssigkeit und / oder das Stranggut übertragbar ist. Ein zusätzlicher thermischer Eintrag erhöht die chemischen Wirkungen, indem die Behandlungsflüssigkeit schneller auf die gewünschte Reaktionstemperatur gebracht wird und damit früher und intensiver reagiert. Die Erfindung ist deshalb vorteilhaft u.a. auch auf Stranggut 1 aus IF-Stählen anwendbar (IF = Interstitial Free Steel).The object is achieved according to the invention in that the treatment channel is formed on the top by means of lined up floating bodies that facing the continuous material, each with one or more, distributed area Heat exchangers are provided, whose thermal energy on the treatment liquid and / or the continuous material is transferable. An additional thermal entry increases the chemical effects by making the treatment liquid on faster the desired reaction temperature is brought and thus earlier and more intensely responding. The invention is therefore advantageous i.a. also on extrusion 1 made of IF steels applicable (IF = Interstitial Free Steel).
Eine weitere Verbesserung des Wirkungsgrades solcher Vorrichtungen wird in Kombination mit chemischen Reaktionen dadurch erzielt, dass den flächenverteilten Wärmetauschern Strömungsleitbleche zugeordnet sind, die nach unten vorstehend zur Vermischung der Behandlungsflüssigkeits-Strömung dienen.A further improvement in the efficiency of such devices is combined achieved with chemical reactions in that the area-distributed Heat exchangers are assigned flow baffles that protrude downward serve to mix the treatment liquid flow.
Vorteilhafterweise sind die Strömungsleitbleche zwischen zwei Wärmetauschern, seitlich von einem Wärmetauscher und / oder vor einem oder vor einem Paar von Wärmetauschern angeordnet. Dadurch wird eine besonders intensive Durchwirbelung der Behandlungsflüssigkeit erzielt.The flow baffles between two heat exchangers are advantageously to the side of a heat exchanger and / or in front of or in front of a pair of Heat exchangers arranged. This creates a particularly intensive vortex the treatment liquid achieved.
Die Übertragung der Wärmeenergie auf das Stranggut und / oder die Behandlungsflüssigkeit erfolgt besonders intensiv, indem die Wärmetauscher jeweils aus an der Unterseite der Schwimmkörper verlegten Heizrohren oder Heizplatten bestehen.The transfer of the thermal energy to the extrudate and / or the treatment liquid is carried out particularly intensively by turning the heat exchanger off at the There are heating pipes or heating plates laid on the underside of the float.
Weitere Merkmale ergeben sich dadurch, dass die Heizrohre schlangenförmig zu Heizwaben verlegt sind. Damit ist eine hohe Flächenausnutzung und eine hohe Wärmebelegung der zur Verfügung stehenden Grundfläche verbunden. Further characteristics result from the fact that the heating pipes are serpentine Heating combs are installed. This means a high use of space and a high one Heat allocation of the available base area connected.
Eine weitere Ausgestaltung sieht vor, dass die Heizrohre aus PVDF oder aus PTFE hergestellt und mit Wasserdampf von ca. 130 - 135 °C betrieben sind. Diese Ausbildung sichert eine gute Wärmebelastbarkeit bei relativ hohen Temperaturen.Another embodiment provides that the heating pipes made of PVDF or PTFE manufactured and operated with water vapor at approx. 130 - 135 ° C. This training ensures good heat resistance at relatively high temperatures.
Für die Gestaltung und Handhabung der Wärmetauscher ist es weiter vorteilhaft, dass die Schwimmkörper mit den Wärmetauschern jeweils mit Abstand zu einem umgebenden, dem Schwimmkörper zugewandt offenen Deckelgehäuse befestigt sind.For the design and handling of the heat exchanger, it is also advantageous that the floating bodies with the heat exchangers are each at a distance from one surrounding, open lid housing facing the floating body attached are.
Dazu ist vorgesehen, dass das Deckelgehäuse mittels mehreren Abstandshaltern mit dem Schwimmkörper verbunden ist.For this purpose, it is provided that the cover housing with several spacers the floating body is connected.
Die Handhabung des Schwimmkörpers, des Wärmetauschers und des Deckelgehäuses wird ferner dadurch erleichtert, dass das Deckelgehäuse zusammen mit dem Schwimmkörper mittels eines Hebegeschirrs oder einer Hydraulikeinrichtung heraushebbar oder auf die Behandlungskammer aufsetzbar ist. Dadurch kann der Wärmetauscher außerhalb der Vorrichtung leicht und schnell ausgetauscht oder repariert werden.The handling of the float, the heat exchanger and the cover housing is further facilitated in that the lid housing together with the Float can be lifted out using lifting gear or a hydraulic device or can be placed on the treatment chamber. This allows the heat exchanger easily and quickly replaced or repaired outside the device become.
Schließlich ist vorgesehen, dass der Schwimmkörper aus Kunststoff hergestellt ist, wodurch eine erheblich leichte Bauweise geschaffen werden kann.Finally, it is provided that the floating body is made of plastic, whereby a considerably light construction can be created.

liegend eine erste Behandlungskammer 3 und eine zweite Behandlungskammer
4 auf. Das Stranggut 1 wird mit Behandlungsflüssigkeit 5 aus Düsen 6 mit
Flüssigkeitsstrahlen 7 derart bestrahlt, dass eine turbulente Behandlungsflüssigkeits-Strömung
5a besteht. Die Flüssigkeitsstrahlen 7 sind am Kanaleingang 8 in Strangtransportrichtung
9 eingestellt und am Kanalausgang 10 zur Strangtransportrichtung

oder mehreren, flächenverteilten Wärmetauschern 12 bestückt sind, deren Wärmeenergie
auf die Behandlungsflüssigkeit 5 und / oder das Stranggut 1 übertragen wird.
Die mit der angestrebten Eintrittstemperatur eintretende Behandlungsflüssigkeit 5
intensiviert die chemische Reaktion zwischen der Oberfläche des Strangguts 1, insbesondere
von Walzband 1a, und führt zu intensiveren Reinigungsvorgängen und
damit zu einer Optimierung des Prozesses und zu einer größeren Durchsatzleistung.The
Die Turbulenz trägt zu diesen Vorgängen ebenfalls bei, so dass in Kombination mit
der erwärmt eingebrachten Behandlungsflüssigkeit 5 eine deutliche Verbesserung
des Prozesses stattfindet. Für diesen Effekt sorgen flächenverteilte Strömungsleitbleche

Wärmetauschern 12, seitlich von einem Wärmetauscher 12 und / oder vor einem
oder vor einem Paar von Wärmetauschern 12 in Strangtransportrichtung 9 angeordnet.As can also be seen from FIG. 2, the

geschlossenen Ausschnitten 11b der Schwimmkörper 11. Die Heizrohre sind aus
PVDF (Polyvinyli-denfluorid ) oder PTFE (Polytetrafluorethylen) hergestellt und führen

dem Schwimmkörper 11 und dem Deckelgehäuse 17 bestimmt. Das Deckelgehäuse
17 ist als Einheit zusammen mit dem Schwimmkörper 11 und den Wärmetauschern
12 mittels eines Hebegeschirrs 19 oder mittels einer Hydraulikeinrichtung
heraushebbar oder auf die Behandlungskammer 3 bzw. 4 wieder aufsetzbar. Der
Schwimmkörper 11 kann aus Kunststoff hergestellt sein, um ein nur geringes Gewicht
einzunehmen und etwaigen störenden Dämpfen aus der Behandlungsflüssigkeit
