Description

Die Erfindung betrifft eine Anlage zur kontinuierlichen Behandlung von Stahlbändern, insbesondere zum Beizen, mit einem Behandlungsbehälter, der aus Kunststoff, vorzugsweise aus Polypropylen (PP) besteht und mit Abquetschwalzen an den Enden des Behandlungsbehälters.The invention relates to a system for the continuous treatment of Steel strips, in particular for pickling, with a treatment container, made of plastic, preferably made of polypropylene (PP) and with Squeezing rollers at the ends of the treatment tank.

Derartige Anlagen sind z.B. aus der US 5,566,694 bekannt. Hier wird zwischen zwei Endkammern mit Abquetschwalzen ein Beizbehälter eingehängt. Bei Ausführung in Kunststoff kann dabei durch das große Gewicht der Beizsäure und die verwendeten Temperaturen ein Durchhang des Beizbehälters auftreten. Wird die Endkammer ebenfalls aus Kunststoff gefertigt, kann es bei der Aufhängung zu Verformungen und damit zu Problemen speziell der Abdichtung kommen. Ein Aufstauen der Beizflüssigkeit ist praktisch nicht möglich, da in diesem Fall unter anderem der Flüssigkeitsspiegel über der Labyrinthdichtung zwischen Beizbehälter und Endkammer liegen würde.Such systems are e.g. from US 5,566,694. Here is suspended between two end chambers with squeeze rollers a pickling tank. When running in plastic can thereby by the large Weight of the pickling acid and the temperatures used a slack of the pickling tank occur. If the end chamber also made of plastic made, it can be used in the suspension to deformations and thus Problems especially of sealing come. A damming up of the pickling liquid is practically impossible, because in this case, among others, the Liquid level above the labyrinth seal between pickling tank and Endkammer would lie.

Die Erfindung ist daher dadurch gekennzeichnet, daß die Abquetschwalzen in einem vom Behandlungsbehälter getrennten und mit Abstand davon angeordneten Behälter vorgesehen sind dass der Behandlungsbehälter und der Behälter der Abquetschwalzen mit einem mit einem das Band vollständig umschließenden und den Abstand von Behandlungsbehälter und weiteren Behälter überbrückenden Verbindungsschacht verbunden sind. Dadurch kann der Hauptstrom des Säurekreislaufes im Behandlungsbehälter erfolgen und eine Abdichtung ist nur gegenüber geringen Flüssigkeitsmengen erforderlich und es kann definiert ein Dehnungsausgleich erreicht werden. Weiters kann sich der Behandlungsbehälter frei ausdehnen, da keine festen Verbindungen zu anderen Bauteilen bestehen. Auch sind keine komplizierten Dichtungen erforderlich.The invention is therefore characterized in that the squeeze rolls in a separate from the treatment tank and at a distance arranged container are provided that the treatment tank and the container of squeeze rolls with one with a Band completely surrounding and the distance from Treatment tank and other container bridging connection shaft are connected. This allows the main stream of the Acid cycle in the treatment tank and a seal is only necessary for small amounts of liquid and it can defines a strain compensation can be achieved. Furthermore, the Expand treatment container freely, as no firm connections to consist of other components. Also, no complicated seals required.

Eine vorteilhafte Weiterbildung der Erfindung der Erfindung ist dadurch gekennzeichnet, dass der Verbindungsschacht als Teleskopschacht ausgeführt ist. Damit können die unterschiedlichen Dehnungen von Behandlungsbehälter und Behälter mit Abquetschwalzen besonders günstig beherrscht werden.An advantageous development of the invention of the invention is characterized in that the connection shaft is designed as a telescopic shaft is. Thus, the different strains of Treatment tank and container with squeeze rollers especially be controlled low.

Eine günstige Weiterbildung der Erfindung ist dadurch gekennzeichnet, daß an mindestens einem Ende des Behandlungsbehälters ein Ablauf vorgesehen ist.

Dadurch kann sich der Behandlungsbehälter nach beiden Seiten hin frei ausdehnen, ohne Probleme einer allfälligen Aufwölbung des Bodens.A favorable development of the invention is characterized in that that the treatment container is arranged in a cup of plastic and preferably in the middle with this firmly connected. This can the treatment container to expand freely on both sides, without problems of a possible bulging of the soil.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß der Verbindungsschacht bis an die Abquetschwalzen heranreicht, wobei der Verbindungsschacht an den Abquetschwalzen abgedichtet sein kann. Mit dieser Variante kann ein höherer Flüssigkeitsspiegel im Behandlungsbehälter eingesetzt werden, wodurch sich die Behandlungslänge des Bandes auf die Distanz zwischen den Abquetschwalzensätzen erhöht. Damit können bei sonst gleichbleibender Ausführung auch höhere Bandgeschwindigkeiten und damit eine höhere Produktion erreicht werden.An advantageous embodiment of the invention is characterized in that that the connection shaft reaches as far as the squeeze rolls, the connection shaft being sealed at the squeeze rolls can. With this variant, a higher liquid level in the Treatment tanks are used, thereby increasing the treatment length of the band to the distance between the squeegee sets elevated. This can also higher in otherwise constant execution Tape speeds and thus achieved a higher production become.

Das Stahlband 5 läuft in Richtung A innerhalb der Behandlungsflüssigkeit 6 mit einem Flüssigkeitsniveau 7. Am Ende des Behandlungsbehälters 1 ist ein Auslaufschacht 8 vorgesehen, in den die Flüssigkeit abrinnt und über ein seitlich angebrachtes Auslaufrohr 9 abgeführt wird. Zur besseren Einstellung des Flüssigkeitsniveaus 7 ist eine, vorteilhafterweise herausnehmbare, Schutzleiste 10 vorgesehen. Die Schutzleiste 10 ist so ausgeführt, daß das Band etwa oberhalb der Wand 11 des Auslaufschachtes 8 aus der Flüssigkeit austaucht. Die gegenüberliegende Wand 12 kann sich durch die Dehnung in Richtung des Pfeiles D in der Tasse 4 verschieben.The steel strip 5 runs in the direction A within the treatment liquid 6 with a liquid level 7. At the end of the treatment tank. 1 a discharge chute 8 is provided into which the liquid runs off and is discharged via a laterally mounted outlet pipe 9. For better Adjustment of the fluid level 7 is one, advantageously removable, Protection strip 10 is provided. The protective strip 10 is designed that the band approximately above the wall 11 of the outlet shaft. 8 emerges from the liquid. The opposite wall 12 may be by stretching in the direction of arrow D in the cup 4 move.

Getrennt vom Behandlungsbehälter 1 ist ein Behälter 13 vorgesehen, in dem sich die Abquetschwalzen 14, 14' befinden. Dieser Behälter kann auch oben geschlossen sein. Ein gleichartiger Behälter 13 samt Abquetschwalzen 14, 14' ist am anderen Ende des Behandlungsbehälters 1 vorgesehen. Die Verbindung von Behälter 1 und Behälter 13 wird durch einen Verbindungs- oder Zwischenschacht 15 hergestellt.Separated from the treatment tank 1, a container 13 is provided, in the squeezing rollers 14, 14 'are located. This container can also be closed at the top. A similar container 13 together Squeeze rolls 14, 14 'are at the other end of the treatment tank 1 provided. The connection of container 1 and container 13 is made by a connection or intermediate shaft 15.

Durch diesen Schacht 15 wird das Band 5 geführt. Bei der vorliegenden Variante gelangen nur geringe Flüssigkeitsmengen, wenn überhaupt, in den Verbindungsschacht 15. Die vom Band abtropfende Flüssigkeit wird dabei vom Verbindungsschacht 15 aufgefangen.Through this slot 15, the band 5 is guided. At the present Variant reach only small amounts of liquid, if any, in the connection shaft 15. The dripping liquid from the tape is thereby caught by the connection shaft 15.

Der Verbindungsschacht 15 ist an seinem Ende 16 fest mit dem Behandlungsbehälter 1 verbunden. Die Verbindung kann eine Steck- oder auch Flanschverbindung sein. Eine freie Bewegung des Verbindungsschachtes 15 in Richtung zu den Abquetschwalzen 14, 14' ist möglich, so daß ein Längenausgleich in einfacher Weise erfolgen kann.The connection shaft 15 is fixed at its end 16 to the treatment tank 1 connected. The connection can be a plug-in or too Be flange connection. A free movement of the connection shaft 15 in the direction of the squeezing rollers 14, 14 'is possible, so that a Length compensation can be done in a simple manner.

Gleiche Bauteile weisen dieselben Bezugsziffern auf wie in Fig. 1. Anstelle des Verbindungsschachtes 15 der Fig. 1 ist hier ein Teleskopschacht 17 zur Verbindung des Behandlungsbehälters 1 mit dem Behälter 13 vorgesehen, wobei dieser an seinem Ende 18 an der Wand 12 des Behälters 1 angeflanscht ist. Der Teleskopschacht 17 wird an seinem anderen Ende in einem Dichtstück 19 angebrachten Schlitzen 20 geführt. So kann in einfacher Weise die Dehnung des Behälters 1 aufgefangen werden. Der Schlitz 20 wirkt dabei mit dem Ende des Teleskopschachtes 17 als Labyrinthdichtung. Statt des Teleskopschachtes 17 kann z.B. auch ein rechteckiger Faltenbalg verwendet werden, der die Dehnung aufnimmt. Durch teilweises oder vollständiges Absperren des Ablaufrohres 9 kann die Ablaufmenge verringert werden, wodurch ein Ansteigen des Flüssigkeitsspiegels im Behälter 1 von 7 auf 7' erfolgt. Um das maximale Flüssigkeitsniveau festzulegen, kann seitlich ein Sicherheitsüberlauf 21 vorgesehen sein. Durch diese Ausführung verlängert sich die Behandlungslänge des Bandes beidseitig von den Wänden 11 bis zu den Abquetschwalzen 14, 14', wodurch auch bei höheren Bandgeschwindigkeiten ausreichende Behandlungszeiten erreicht werden. Ein Teil der Behandlungsflüssigkeit, z.B. Beizsäure, wird hier durch den Teleskopschacht 17 in den Behälter 13 geführt, von wo die Flüssigkeit wieder in den Kreislauf zurückgeführt wird. Trotz des hohen Flüssigkeitsniveaus 7' ist nur eine Abdichtung des Behälters 13 gegen geringe Flüssigkeitsmengen erforderlich, da das Flüssigkeitsniveau im Behälter 13 wesentlich unterhalb des Bereiches der Dehnungsaufnahme liegt.Fig. 2 shows a variant of the invention, which also referred to as a dust trough can be. It is for high tape speeds, preferably from 150 m / min, suitable. The same components have the same reference numerals as in Fig. 1. Instead of the connection shaft 15 of Fig. 1 is here a telescopic shaft 17 for connecting the treatment tank 1 with the container 13 is provided, wherein this at its end 18 at the Wall 12 of the container 1 is flanged. The telescopic shaft 17 is at its other end in a sealing piece 19 attached slots 20 led. Thus, the elongation of the container 1 can be easily absorbed become. The slot 20 acts with the end of the telescopic shaft 17 as a labyrinth seal. Instead of the telescopic shaft 17 can e.g. Also, a rectangular bellows can be used, which the Elongation absorbs. By partially or completely shutting off the Drain pipe 9, the flow rate can be reduced, creating a Increase of the liquid level in the container 1 from 7 to 7 'takes place. Around set the maximum fluid level, can laterally Safety overflow 21 may be provided. Extended by this design the treatment length of the band on both sides of the Walls 11 to the squeezing rollers 14, 14 ', which also at higher belt speeds achieved sufficient treatment times become. A part of the treatment liquid, e.g. Pickling acid, will guided here by the telescopic shaft 17 in the container 13, from where the Liquid is returned to the circulation. Despite the high Liquid levels 7 'is only a seal of the container 13 against small amounts of liquid are required, as the liquid level in the Container 13 substantially below the range of strain absorption lies.
