Description

Verfahren und Vorrichtung zum Absaugen von Ablaufwasser im Innenbogen von Trägervorprofil-GießmaschinenMethod and device for extracting waste water in the inner arch of beam pre-profile casting machines
Die Erfindung betrifft ein Verfahren zum Auffangen und Abführen von Ablaufwasser aus dem Innenbogen der Strangführung einer Beam Blank- Gießmaschine, bei welcher der vergossene Strang zur Erstarrung gebracht und die erforderliche Wärmeabfuhr unter anderem über Spritzwasser erzielt wird, wobei sich gegebenenfalls auf dem Innenbogen des Stranges Ablaufwasser sammelt. Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for collecting and discharging waste water from the inner curve of the strand guide of a beam blank casting machine, in which the cast strand is solidified and the required heat dissipation is achieved, inter alia, by spray water, with drain water possibly being located on the inner curve of the strand collects. The invention also relates to an apparatus for performing the method.
Bei Trägervorprofil- oder Schienenvorprofil-Gießmaschinen, sogenannten Beam Blank-Gießmaschinen wird das vergossene Format innerhalb der Strangführung zur Erstarrung gebracht. Die Erstarrung einer äußeren, festen Strangschale erfolgt bereits in der Kokille durch Wärmeleitung an wassergekühlte Kupferplatten. Das Beam Blank-Vorprofil wird in einem Gießradius erzeugt.In beam pre-profile or rail pre-profile casting machines, so-called beam blank casting machines, the cast format is solidified within the strand guide. An outer, solid strand shell solidifies already in the mold by heat conduction on water-cooled copper plates. The beam blank pre-profile is created in a casting radius.
Weitere Wärmeabfuhr wird innerhalb der Strangführung durch Rollenkontakt, Überspritzwasser und Wärmestrahlung erzielt. Prinzipbedingt sammelt sich auf dem Innenbogen des Stranges Überschuß- bzw. Ablaufwasser. Dieses addiert sich in Strangabzugsrichtung von Düsenreihe zu Düsenreihe.Further heat dissipation is achieved within the strand guide through roller contact, over-splash water and heat radiation. In principle, excess or drain water collects on the inner arch of the strand. This adds up in the strand withdrawal direction from the nozzle row to the nozzle row.
Das angesammelte Wasser behindert einerseits den Wärmeübergang durch Spritzkühlung und würde andererseits zu einer Wasseransammlung vor der Brennschneidmaschine führen, wenn es nicht aus dem Steg des Stranges bzw. aus dem Steg des Beam Blanks entfernt werden würde.The accumulated water on the one hand hinders the heat transfer by spray cooling and on the other hand would lead to water accumulation in front of the flame cutting machine if it were not removed from the web of the strand or from the web of the beam blank.
Der derzeitige Stand der Technik ist charakterisiert beispielsweise durch Ausblasen des Wassers aus dem Innenbogen des Stranges mittels Druckluft. Dieses Ausblasen erfolgt unter hohem Energieeinsatz und mit erheblichem In- Standhaltungsaufwand für Kompressoren, die erforderlich sind, um die benötigten Druckluftmengen zu erzeugen. Des weiteren schädigt das unkontrollierte über die Flanschkanten des Beam Blank-Vorprofils geblasene Wasser die Qualität des erzeugten Profils, wodurch Materialverluste verursacht werden können.The current state of the art is characterized, for example, by blowing the water out of the inner bow of the strand using compressed air. This blow-out takes place with high energy input and with considerable maintenance expenditure for compressors, which are necessary to generate the required compressed air quantities. Furthermore, the uncontrolled damages Water blown over the flange edges of the beam blank pre-profile ensures the quality of the profile created, which can result in material losses.
Durch das Dokument JP 58 15 7559 A1 ist das Absaugen von Stegwasser bei Beam Blanks im Prinzip bekannt. Gemäß diesem Dokument wird überschüssi- ges Kühlwasser durch ein messerartig geformtes Eingangs-Saugrohr aufgenommen und mittels Unterdruck am Ende eines mit rundem Querschnitt gebildeten Ausgangsrohrs abgesaugt. Der Unterdruck wird durch ein konzentrisches Mantelrohr erzeugt, mittels welchem Luft unter Druck am Ende des Ausgangsrohres vorbeiströmt und im Zusammenwirken mit diesem den Unterdruck er- zeugt. Der Druckunterschied ist jedoch relativ gering und erlaubt nur, Reste des Kühlwassers aufzusaugen. Dabei ist über dem Eingangs-Saugrohr noch eine schräge Fläche zum Abweisen von Überschuss-Kühlwasser angeordnet, die sich über dem Eingangs-Saugrohr in entgegengesetzte Querrichtungen teilt, so dass Kühlwasserreste zu beiden Seiten des Gießstranges ablaufen und geson- dert aufgefangen werden müssen.From JP 58 15 7559 A1, the extraction of web water from beam blanks is known in principle. According to this document, excess cooling water is taken up through a knife-shaped inlet suction pipe and sucked off by means of negative pressure at the end of an outlet pipe formed with a round cross section. The negative pressure is generated by a concentric casing tube, by means of which air flows past the end of the outlet tube under pressure and, in cooperation with it, generates the negative pressure. However, the pressure difference is relatively small and only allows residues of the cooling water to be sucked up. In this case, an inclined surface for repelling excess cooling water is arranged above the inlet suction pipe, which divides in opposite transverse directions above the inlet suction pipe, so that cooling water residues run off on both sides of the casting strand and have to be collected separately.
Prinzipiell sind Beam Blank-Profile bzw. Vorprofilstränge wie Trägervorprofile oder Schienenvorprofile so geformt, dass Restwassermengen nicht selbstständig über die seitlichen Flanschkanten austreten können. Weil die Platz- und Raumverhältnisse schon durch die Bedingungen in der Kühlkammer sowie innerhalb der Strangführung sehr beengt sind, fehlt es an ausreichendem Raum, um aufwendige Vorrichtungen zur Entfernung des Stegwassers installieren zu können. Ein Umleiten des Wassers durch entsprechende Vorrichtungen zur Zuführung in Saugrohre gestaltet sich durch die sich ständig bewegende raue Strangoberfläche äußerst schwierig. Deshalb sind praktizierte Verfahren zum einfachen Ausblasen des Wassers relativ energieaufwendig und schädigen das Produkt.In principle, beam blank profiles or pre-profile strands, such as beam pre-profiles or rail pre-profiles, are shaped in such a way that residual water cannot escape through the side flange edges. Because the space and space conditions are already very cramped by the conditions in the cooling chamber and within the strand guide, there is insufficient space to install complex devices for removing the web water. Redirecting the water through appropriate devices for feeding into suction pipes is extremely difficult due to the constantly moving rough strand surface. Therefore, practiced methods for simply blowing out the water are relatively energy-intensive and damage the product.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Auf- gäbe zugrunde, ein Verfahren und eine Vorrichtung anzugeben, welche die folgenden Kriterien erfüllen sollen: - Ein möglichst vollständiges Sammeln und Auffangen von Ablaufwasser im Dauerbetrieb unter Bedingungen des Stranggießens von Stahl sowie Abfördern von Ablaufwasser, ohne die Materialqualität des Gießstranges negativ zu beeinflussen. - Vermeidung einer Kollision des Gießstranges mit Wasserleiteinrichtungen.Starting from the aforementioned prior art, the invention is based on the object of specifying a method and a device which are intended to meet the following criteria: - The most complete possible collection and collection of waste water in continuous operation under the conditions of continuous casting of steel and removal of waste water without negatively affecting the material quality of the casting strand. - Avoiding a collision of the casting strand with water guiding devices.
- Unkomplizierte, raumsparende Bauart und geringer Installationsaufwand in der Stranggießanlage.- Uncomplicated, space-saving design and low installation effort in the continuous caster.
- Wartungsarme bzw. energiesparende Saugeinrichtung zum Ableiten von Ablaufwasser im Innenbogen einer Stranggießmaschine. - Verwendung einfacher Mittel zur Anpassung der Saugein ichtung auf unterschiedliche Strangformate.- Low-maintenance or energy-saving suction device for draining waste water in the inner bend of a continuous casting machine. - Use of simple means for adapting the suction device to different strand formats.
Zur Lösung der Aufgabe wird mit der Erfindung bei einem Verfahren zum Auffangen und Abführen von Ablaufwasser aus dem Innenbogen der Strangfüh- rung einer Beam Blank-Gießmaschine gemäß den Merkmalen des Oberbegriffs von Anspruch 1 vorgeschlagen, das Ablaufwasser unter Verwendung eines Saugkopfes aufzufangen und das im Saugkopf aufgefangene Ablaufwasser unter Verwendung von Fluidisatoren bzw. Impulshemmern zu fluidisieren und das fluidisierte Ablaufwasser abzusaugen und das Wasser-Luft-Gemisch in Wasser und Luft aufzutrennen. Mit diesen Maßnahmen wird innerhalb des Saugkopfes das Ablaufwasser fluidisiert und pneumatisch förderfähig gemacht. Infolge des Fluidisierens des Ablaufwassers kann dieses mit geringem energetischem Aufwand abgesaugt werden und anschließend einer Trennvorrichtung für Wasser und Luft zugeführt werden. Die Ausbildung eines Saugkopfes be- deutet eine unkomplizierte und raumsparende Bauart, die mit geringem Aufwand in der Beam Blank-Gießmaschine installiert werden kann.To achieve the object, the invention proposes in a method for collecting and discharging drain water from the inner curve of the strand guide of a beam blank casting machine according to the features of the preamble of claim 1 to collect the drain water using a suction head and that in the suction head fluidize collected drain water using fluidizers or pulse inhibitors and suck off the fluidized drain water and separate the water-air mixture into water and air. With these measures, the drain water is fluidized within the suction head and made pneumatically eligible. As a result of the fluidization of the drain water, it can be sucked off with little energy expenditure and then fed to a separating device for water and air. The design of a suction head means an uncomplicated and space-saving design that can be installed in the Beam Blank casting machine with little effort.
In Ausgestaltung des Verfahrens wird vorgeschlagen, dass Fluidisatoren mit einer Vielzahl im Saugkopf verteilt angeordneter Luftdüsen ausgebildet werden und der Saugkopf in der Weise geformt wird, dass ein Fluidisierungsraum zurIn an embodiment of the method, it is proposed that fluidizers are formed with a plurality of air nozzles distributed in the suction head and the suction head is shaped in such a way that a fluidization chamber is provided
Expansion des aufzunehmenden Wassers gebildet wird. Bei einer zweckmäßi- gen Ausgestaltung ist auch vorgesehen, dass als Fluidisatoren lose Metallteile oder Ketten im Aufnahmeraum des Saugkopfes angeordnet sein können.Expansion of the water to be absorbed is formed. With an expedient Gen embodiment is also provided that loose metal parts or chains can be arranged as fluidizers in the receiving space of the suction head.
In Fortbildung des Verfahrens wird erfindungsgemäß vorgeschlagen, dass der Saugkopf mittels eines Manipulators im bzw. am Strang geführt und/oder posi- tioniert wird, wodurch ermöglicht ist, dass der Saugkopf aus größerer Entfernung und von einer Bedienungswarte aus für einen optimalen Einsatz angesteuert wird.In a development of the method, it is proposed according to the invention that the suction head is guided and / or positioned in or on the strand by means of a manipulator, which makes it possible for the suction head to be actuated from a greater distance and from an operator control room for optimum use.
Um den Saugkopf gegenüber dem Strang- bzw. dem Beam Blank-Vorprofil ab- zudichten, werden zweckmäßigerweise Abdichtmittel wie Bürsten oder gummielastische Abdichtleisten vorgeschlagen.In order to seal the suction head with respect to the strand or the beam blank pre-profile, sealing means such as brushes or rubber-elastic sealing strips are expediently proposed.
Da Beam Blank-Gießmaschinen für unterschiedliche Strangformate einsetzbar sind, ist es nach einem weiteren Vorschlag der Erfindung zweckmäßig, dass der Saugkopf an die unterschiedlichen Strangformate anpassbar ausgebildet ist und unter Verwendung von Schnelltrenn- oder Verbindungsmitteln zum Anschließen an eine Absaugeinrichtung montierbar ist.Since beam blank casting machines can be used for different strand formats, it is expedient according to a further proposal of the invention that the suction head is designed to be adaptable to the different strand formats and can be installed using quick disconnect or connecting means for connection to a suction device.
Besonders vorteilhaft ist ein weiterer Vorschlag, wonach das Ablaufwasser mittels des Saugkopfes an einer oder an mehreren Stellen entlang der metallurgischen Länge des Gießstranges bzw. des Beam Blank unterhalb der Kokille abgesaugt wird.A further proposal is particularly advantageous, according to which the drain water is sucked off at one or more points along the metallurgical length of the casting strand or the beam blank below the mold by means of the suction head.
Die Erfindung betrifft auch eine Vorrichtung zur Durchführung des Verfahrens. Diese Vorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 7 ist gekennzeichnet durch wenigstens einen, entlang der Strangführung angeordneten oder führbar gehaltenen, an einer Absaugvorrichtung anschließbaren Saugkopf mit Fluidisatoren und mit Mitteln zum Führen des Saugkopfes entlang des Beam Blank-Vorprofils. Mit Hilfe derartig ausgebildeter Saugköpfe wird das Ablaufwasser pneumatisch förderfähig gemacht und das abgesaugte Wasser kann durch den Saugzug über geeignete Rohre oder Leitungen bis zu Wasser- abscheidern transportiert und von dort weitergeleitet bzw. nach entsprechender Reinigung in die Kühleinrichtung der Gießmaschine zurückgeführt werden.The invention also relates to an apparatus for performing the method. This device with the features of the preamble of claim 7 is characterized by at least one suction head arranged along the strand guide or held in a guidable manner and connectable to a suction device with fluidizers and with means for guiding the suction head along the beam blank pre-profile. With the help of suction heads designed in this way, the drainage water is made pneumatically conveyable and the extracted water can be sucked through suitable pipes or lines up to water. separators are transported and passed on from there or, after appropriate cleaning, are returned to the cooling device of the casting machine.
In Ausgestaltung der Vorrichtung ist der Saugkopf in der Art eines glockenförmigen Aufnahmeraumes ausgebildet, wobei der Aufnahmeraum die Fluidisato- ren wie Düsen, lose Metallteile oder Ketten zum Fluidisieren des aufgefangenen Wassers enthält. Diese Anordnung läßt eine sehr kompakte Bauart des Saugkopfes zu, so dass dieser raumsparend in der Strangführung untergebracht werden kann. Vorteilhaft ist, wenn in mehreren Bereichen der Stranggießanlage Saugköpfe angeordnet sind, die das Ablaufwasser frühzeitig aus dem Innenbogen des Beam Blanks absaugenIn an embodiment of the device, the suction head is designed in the manner of a bell-shaped receiving space, the receiving space containing the fluidizers such as nozzles, loose metal parts or chains for fluidizing the collected water. This arrangement allows a very compact design of the suction head, so that it can be accommodated in the strand guide in a space-saving manner. It is advantageous if suction heads are arranged in several areas of the continuous caster, which suck off the drain water at an early stage from the inner bend of the beam blank
Eine besonders vorteilhafte Ausgestaltung der Absaugvorrichtung sieht vor, dass der Saugkopf mittels Schnelltrenn- bzw. Verbindungsmittel als Wechselkopf zur Anpassung an andere Beam Blank-Formate ausgeführt ist. Da insbe- sondere bei der Walzung von Trägern auch unterschiedliche Beam Blank- Vorprofile gegossen werden, ist die hier vorgeschlagene Maßnahme zur Anpassung des Saugkopfes besonders interessant.A particularly advantageous embodiment of the suction device provides that the suction head is designed as a replaceable head by means of quick disconnect or connecting means for adapting to other beam blank formats. Since different beam blank pre-profiles are cast in particular when rolling beams, the measure proposed here for adapting the suction head is particularly interesting.
Ein optimierter Einsatz der Saugeinrichtung ergibt sich dann, wenn ein Mani- pulator zur Positionierung des Absaugkopfes vorgesehen ist, wobei der Saugkopf in einem Abstand von 0 bis 40 mm zur Oberfläche des Beam Blank- Formats positionierbar ist. Durch diese Maßnahme wird vermieden, dass der Saugkopf mit der in Einzelfällen sehr rauen Oberfläche des Beam Blanks in Berührung kommt und entweder der Beam Blank selber oder der Saugkopf be- schädigt wird.An optimized use of the suction device results if a manipulator is provided for positioning the suction head, the suction head being positionable at a distance of 0 to 40 mm from the surface of the beam blank format. This measure prevents the suction head from coming into contact with the very rough surface of the beam blank in individual cases and damage to either the beam blank itself or the suction head.
Weitere Ausgestaltungen der erfindungsgemäßen Vorrichtung sind in weiteren Unteransprüchen beschrieben. Einzelheiten, Merkmale und weitere Vorteile der Erfindung ergeben sich aus der nachstehenden Erläuterung eines in den Zeichnungen schematisch dargestellten Ausführungsbeispiels. Es zeigen:Further refinements of the device according to the invention are described in further subclaims. Details, features and further advantages of the invention result from the following explanation of an exemplary embodiment schematically illustrated in the drawings. Show it:

In Figur 1 ist der Strangabschnitt für einen Beam Blank, im vorliegenden Fall ein Trägervorprofil zu sehen. Mit der Bezugsziffer 12 ist die Gießrichtung des Beam Blanks bezeichnet. Die seitlichen Randprofile des Beam Blanks sind mit den Bezugsziffern 11 und 11' versehen.1 shows the strand section for a beam blank, in the present case a carrier pre-profile. Reference number 12 denotes the casting direction of the beam blank. The side edge profiles of the beam blank are provided with the reference numbers 11 and 11 '.
In dem sich ergebenden knochenförmigen Strangprofil 9 befindet sich zwecks Absaugen des sich darin sammelnden Überschuss- bzw. Ablaufwassers der Saugkopf 1. Dieser ist mit Schnelltrenn- oder Verbindungsmitteln 3 an die Absaugeinrichtung 4 anschließbar. Diese besteht aus der Saugleitung 10 und einem Wasserabscheider 13. Durch die an den Saugkopf 1 anschließbare Sau- gleitung 10 wird das im Saugkopf erzeugte und pneumatisch förderbare Wasser-Luft-Gemisch abgeführt. Die Saugleitung 10 ist in - wie gesagt - an eine Trenneinrichtung angeschlossen, in welcher das aufgefangene Wasser-Luft- Gemisch in Wasser und Luft getrennt wird, wonach der Wasseranteil zwecks Wiederverwendung aufbereitet, d. h. von mitgeführten Feststoffen und anderen Stoffen getrennt und zur Wiederverwendung der Beam Blank-Gießmaschine zurückgeführt wird.The suction head 1 is located in the resulting bone-shaped extruded profile 9 for the purpose of sucking off the excess water or waste water collecting therein. This can be connected to the suction device 4 with quick disconnect or connecting means 3. This consists of the suction line 10 and a water separator 13. The suction line 1, which can be connected to the suction head 1, removes the pneumatically conveyable water-air mixture generated in the suction head. As already mentioned, the suction line 10 is connected to a separating device, in which the collected water-air mixture is separated into water and air, after which the water portion is treated for reuse, i. H. separated from entrained solids and other substances and returned to the Beam Blank casting machine for reuse.
Der Saugkopf 1 ist in Glockenform mit einer unteren Saugöffnung ausgebildet und umschließt einen Fluidisierungsraum zur Expansion des aufzunehmenden Wassers. Weiterhin enthält der Saugkopf 1 in seinem Innenraum zum Fluidisie- ren des im Saugkopf 1 aufgefangenen Ablaufwassers sogenannte Fluidisatoren bzw. Impulshemmer, wodurch das Ablaufwasser pneumatisch förderfähig gemacht wird. Die Fluidisierung des aufgefangenen Ablaufwassers wird bevorzugt dadurch verbessert, dass im Saugkopf verteilt angeordnete Luftdüsen innerhalb des glockenförmigen Fluidierungsraumes zwecks Expansion des aufzunehmenden Wassers vorhanden sind. Mit deren Hilfe wird das aufzufangende Wasser kräftig mit Luft durchwirbelt und wird dadurch pneumatisch förderfähig gemacht. Die Fluidisatoren können auch Ketten oder ähnliche mechanische Einrichtungen umfassen.The suction head 1 is designed in a bell shape with a lower suction opening and encloses a fluidization space for the expansion of the water to be absorbed. Furthermore, the suction head 1 contains so-called fluidisers in its interior for fluidizing the drain water collected in the suction head 1 or pulse inhibitor, which makes the drain water pneumatically eligible. The fluidization of the collected drain water is preferably improved in that air nozzles distributed in the suction head are present within the bell-shaped fluidization space for the purpose of expanding the water to be taken up. With their help, the water to be collected is swirled vigorously with air and is thereby made pneumatically eligible. The fluidizers can also include chains or similar mechanical devices.
