Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Stranggießvorrichtung zum Rundstranggießen von flüssigem Metall, insbesondere von flüssigem Stahl, in mehrsträngigen Stranggießvorrichtungen, wobei jeweils auf eine Stranggießkokille ein Stützrollengerüst folgt und mehrere Strangadern untereinander parallel verlaufen und wobei die Stranggießkokille aus einem vorgeschalteten Verteilergefäß mit Schmelze gespeist wird.The invention relates to a method and a continuous casting device for continuous casting of liquid metal, especially liquid steel, in multi-strand Continuous casting devices, with a supporting roller frame on each continuous casting mold follows and several strand veins run parallel to each other and the Continuous casting mold fed with melt from an upstream distributor vessel becomes.
Derartige Mehrstranggießmaschinen werden für 2, 3, 4, 5, 6 oder mehr Stränge gebaut und betrieben. Jeder Stranggießkokille ist eine Oszillationseinrichtung mit einem Hubtisch zugeordnet. Einer Mehrzahl von Stranggießkokillen ist ferner ein Verteilergefäß vorgeschaltet. Es können auch mehrere Verteilergefäße für Gruppen von Stranggießkokillen zugeteilt sein. Die Verteilergefäße werden von einer Gießpfanne entsprechend großen Fassungsvermögens gespeist. Jedoch treten dabei schon Temperaturunterschiede in der Schmelze bei außen liegenden Gießsträngen und / oder bei mehreren Verteilergefäßen auf. Man ist daher bestrebt, die Anzahl der Strangadern zu begrenzen. Diesem Bestreben steht jedoch eine für Mehrstranggießanlagen vorgesehene Produktionsleistung entgegen. Hinzu kommen unterschiedlich große Strangdurchmesser, die sich aus wechselnden Marktforderungen ergeben.Such multi-strand casting machines are built for 2, 3, 4, 5, 6 or more strands and operated. Each continuous casting mold is an oscillation device with one Assigned lifting table. A plurality of continuous casting molds is also a distribution vessel upstream. There can also be several distribution vessels for groups of Continuous casting molds are assigned. The distribution vessels are from a ladle fed according to large capacity. However, it already occurs Temperature differences in the melt in the case of external casting strands and / or with several distribution vessels. One therefore strives to increase the number of Limit strand veins. However, this endeavor stands for multi-strand casting plants planned production output. In addition there are different large strand diameters resulting from changing market demands result.
Den bekannten Mehrstranggießanlagen haften daher Nachteile einer mangelhaften Koordinierung der Produktionsleistung und der Durchmesserverteilung mit der Anzahl der Stränge an. Ebenso sind die Temperaturführung, die Verteilergrößen, die Anzahl der Hubtische mit Oszillationseinrichtungen und Stranggießkokillen besser aufeinander abzustimmen.The known multi-strand caster therefore have disadvantages of an inadequate one Coordination of production performance and diameter distribution with the number of strands. Likewise, the temperature control, the distributor sizes, the Better number of lifting tables with oscillation devices and continuous casting molds to coordinate with each other.
Der Erfindung liegt die Aufgabe zugrunde, die Produktionsleistung einer Mehrstranggießanlage in Abhängigkeit der Durchmesserverteilung auf die Anzahl von Gießlinien abzustimmen.The invention has for its object the production performance of a multi-strand caster depending on the diameter distribution on the number of casting lines vote.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass aus einer kundenspezifischen Durchmesserreihe relativ kleine Strangdurchmesser jeweils in Twin-Kokillen und relativ größere Strangdurchmesser jeweils in Single-Kokillen innerhalb einer einheitlichen Stranggießvorrichtung vergossen werden. Dadurch ist eine hohe Produktionsleistung mit einer kleinstmöglichen Anzahl von Gießlinien möglich, d.h. die relative Produktionsleistung wird erheblich gesteigert. Dabei kann eine höhere Produktionsleistung mit einer geringeren Anzahl von Strangadern erzielt werden.The object is achieved according to the invention in that a customer-specific Row of diameters relatively small strand diameters, each in twin molds and relatively larger strand diameters in single molds within be cast in a uniform continuous casting device. This makes it high Production output possible with the smallest possible number of casting lines, i.e. the relative production output is increased considerably. It can be a higher Production output can be achieved with a smaller number of strand wires.
Gemessen an den bekannten Verfahrensabläufen wird weiter vorgeschlagen, dass mehrere unabhängige Mehrstranggießanlagen mit einer summierten Produktionsleistung in die einheitliche Stranggießvorrichtung mit virtueller Stranganzahl umgerechnet werden und dass für die summierte Produktionsleistung die Anzahl der Stränge auf eine volle Zahl reduziert wird. Dabei kann eine konventionelle Mehrstranggießanlage mit z.B. sechs Strängen durch vier Stränge bei gleich großer Produktionsleistung ersetzt werden.Based on the known procedures, it is further proposed that several independent multi-strand casting plants with a total production output converted into the uniform continuous caster with a virtual number of strands and that for the total production output the number of strands is reduced to a full number. A conventional multi-strand caster can be used with e.g. six strands through four strands with the same production output be replaced.
Für kleinere Strangdurchmesser wird das Twin-System eingesetzt und für größere Strangdurchmesser das Single-System, so dass die Gießleistung der Gießlinie, auf der im Twin-System gegossen wird, jeweils bestehend aus einem Hubtisch, einer Stranggießkokille und einer Oszillationseinrichtung, sich verdoppelt.The twin system is used for smaller strand diameters and for larger ones Strand diameter the single system, so the casting performance of the casting line, on which is cast in the twin system, each consisting of a lifting table, one Continuous casting mold and an oscillation device, doubled.
Eine vorteilhafte Verteilung der Gesamt-Produktionsleistung aus Strängen mit unterschiedlichen Durchmessern wird z.B. derart vorgenommen, dass für Strangdurchmesser von ca. 180 - 240 mm das Twin-System und für Strangdurchmesser von ca. 270 - 406 mm das Single-System eingesetzt wird.An advantageous distribution of the total production output from strands with different Diameters is e.g. made such that for strand diameter from 180 - 240 mm the twin system and for strand diameters of approx. 270 - 406 mm the single system is used.
Die Produktionsleistung kann an einer solchen Mehrfachstranggießanlage durch die vorhandenen Transportanlagen für die Schmelze begrenzt werden. Im Grunde ist daher möglich, dass der Verteiler aus einem Pfannengefäß mit maximal 300 t Fassungsvermögen gespeist wird.The production output of such a multi-strand caster can be achieved through the existing transport systems for the melt can be limited. Basically it is therefore possible that the distributor from a pan vessel with a maximum capacity of 300 t is fed.
Die Stranggießvorrichtung für flüssige Metalle, insbesondere für flüssigen Stahl, mit mehreren parallelen, nebeneinander angeordneten Strangadern, die jeweils durch Stranggießkokillen und anschließendem Stützrollengerüst mit geradem und / oder gebogenem Verlauf gebildet sind, ist vorrichtungstechnisch dahingehend gestaltet, dass das Stützrollengerüst der einheitlichen Stranggießvorrichtung entweder aus jeweils drei nebeneinander angeordneten Profilrollen-Bahnen und jeweils jeder Profilrollen-Bahn zugeordneter Stranggießkokille gebildet ist oder aus nur zwei Profilrollen-Bahnen und einer asymmetrisch aufgebauten Stranggießkokille, die jeweils einer der Profilrollen-Bahnen zugeordnet ist. Dadurch können temperaturbedingte Abstände zwischen den Strängen leicht eingehalten werden, wobei sowohl Stränge mit kleinem Durchmesser in Paaren als auch ein mittlerer Strang mit größerem Durchmesser auf der Anlage gegossen werden kann und nur die Hubtischeinheit anzupassen ist. The continuous casting device for liquid metals, especially for liquid steel, with several parallel, side-by-side strand wires, each through Continuous casting molds and subsequent support roller stand with straight and / or curved course is designed in terms of device technology in such a way that the support roller frame of the unitary continuous casting device either from each three profile roller tracks arranged next to each other and each profile roller track assigned continuous casting mold is formed or from only two profile roller tracks and an asymmetrically constructed continuous casting mold, each of which Profile roller tracks is assigned. This can result in temperature-related distances between the strands are easily maintained, both strands with small Diameter in pairs as well as a medium strand with a larger diameter the system can be cast and only the lifting table unit has to be adjusted.
Nach weiteren Merkmalen ist vorgesehen, dass zwei Profilrollen-Bahnen symmetrisch oder unsymmetrisch zu einer mittleren Profilrollen-Bahn angeordnet sind. Dabei kann das Twin-System eingesetzt werden.According to further features, it is provided that two profile roller tracks are symmetrical or are arranged asymmetrically to a central profile roller track. there the twin system can be used.
Die Größe der Mehrfachstranggießanlage kann sodann dahingehend bestimmt werden, dass bei einer vorgegebenen Anzahl der Gießstränge der Anteil der Produktion der einzelnen Strangdurchmesser an der Jahresproduktion als Richtwert für die Auslegung der Anzahl der Stränge dient. Der Vorteil ist die Berücksichtigung einer wechselnden Marktforderung von ausgewählten Strangdurchmessern, die mengenmäßige Schwerpunkte bilden.The size of the multiple-strand caster can then be determined by that for a given number of casting strands the proportion of production of the individual strand diameters on the annual production as a guideline for the Interpretation of the number of strands is used. The advantage is considering one changing market demand of selected strand diameters, the quantitative Focus on.
