Abstract
Description
Die Erfindung betrifft einen Verteilerrinnenwagen, insbesondere für Zweistrang-Gießanlagen, mit einem auf parallel beabstandeten Schienen verfahrbaren Fahrgestell zur Aufnahme einer heb- und senkbaren sowie quer zur Gießrichtung einstellbaren, mit zwei den beiden Strängen zuordenbaren Gießrohren ausgestatteten Verteilerrinne, durch welche die Stahleinleitung aus wenigstens einer Gießpfanne in zwei in Längsrichtung beabstandete, vergleichsweise schmale Parallel- oder Trichterkokillen erfolgt, wobei das Fahrgestell einen mit zwei Längsträgern und diese verbindenden Querträgern ausgebildeten Rahmen aufweist, dessen Ecken von je einem Fahrschemel mit einem Schienenrad und einem damit zusammenwirkenden Hubgetriebe aufgenommen sind und je einen Auflagepunkt für die Verteilerrinne bzw. für den sie aufnehmenden Rahmen aufweisen.The invention relates to a trough trolley, especially for two-strand casting plants, with one on Movable chassis for parallel spaced rails Inclusion of a liftable and lowerable as well as transverse to the casting direction adjustable, with two assignable to the two strands Casting pipes equipped distribution channel through which the Steel discharge from at least one ladle into two Longitudinally spaced, comparatively narrow parallel or Funnel molds are made, with the chassis having one two side members and cross members connecting them trained frame, the corners of each Subframe with a rail wheel and one with it interacting lifting gear are included and one each Point of contact for the distribution channel or for which it have receiving frame.
Bei herkömmlichen Verteilerrinnenwagen sind die Auflagepunkte der Verteilerrinne bzw. des sie aufnehmenden Rahmens jeweils an den Eckpunkten eines rechteckigen Fahrgestellrahmens symmetrisch zur Längsachse angeordnet. Beim Positionieren der beiden Gießrohre in den Kokillen von Brammenanlagen kann für den Zentriervorgang der beiden Gießrohre eine begrenzte Retativbewegung toleriert werden, weil zwischen Gießrohr und den Breitseiten-Kupferplattenwänden der Kokille genügend Freiraum vorhanden ist. Bei den vergleichsweise erheblich engeren Platzverhältnissen des Gießrohres für Dünnbrammen-Parallel- bzw. Trichterkokillen sind solche Relativbewegungen nicht tolerierbar. Bei einem Abstand der Breitseiten-Kupferplatten solcher Parallel- bzw. Trichterkokillen von beispielsweise 35 mm sind Relativbewegungen zwischen einem Gießrohr und den Kupferplatten der Kokille nicht zulässig.With conventional distribution trough trolleys the support points are the distribution channel or the frame receiving it in each case at the corner points of a rectangular chassis frame arranged symmetrically to the longitudinal axis. When positioning the Both pouring tubes in the molds of slab plants can be used for the centering process of the two pouring tubes is limited Retative movement can be tolerated because between the pouring tube and the broadside copper plate walls of the mold are sufficient There is free space. In the comparatively significant tighter space for the pouring tube for Thin slab parallel or funnel molds are such Relative movements cannot be tolerated. At a distance of Broadside copper plates of such parallel or Funnel molds of 35 mm, for example Relative movements between a pouring tube and the Copper plates of the mold are not permitted.
Die Verteilerrinne als erforderliches Element zwischen Pfanne und Kokille hat wesentlichen Anteil an der Qualität des Produktes. Eine Verschlechterung der Qualität des Stahls durch Aufnahme unliebsamer Elemente wie beispielsweise Sauerstoff und Stickstoff muss möglichst vermieden werden. Größe und Form der Rinne sind daher so zu wählen bzw. zu gestalten, dass infolge günstiger Strömungsverhältnisse in der Schmelze befindliche Verunreinigungen abgeschieden werden können. Die konstruktive Gestaltung muss so erfolgen, dass durch Lasteinwirkung und Krantransport geringstmögliche elastische Deformationen auftreten können, um Schäden am Feuerfestmaterial zu vermeiden. Bleibende Formänderungen, beispielsweise durch Temperaturbelastungen, insbesondere beim Vorheizen, sind nicht zulässig.The distribution channel as a required element between the pan and mold has a significant part in the quality of the Product. A deterioration in the quality of the steel Absorption of undesirable elements such as oxygen and nitrogen should be avoided if possible. Size and shape the gutter must therefore be selected or designed so that due to favorable flow conditions in the melt existing impurities can be separated. The constructive design must be done in such a way that Load and crane transport are the least elastic Deformations can occur to damage the Avoid refractories. Permanent changes in shape, for example, due to temperature loads, especially when Preheating is not permitted.
Während Verteilerrinnen einer Zweistrang-Brammenanlage vor nunmehr 10 Jahren ein durchschnittliches Fassungsvermögen von 15 bis 20 Tonnen hatten, beträgt diese Größe heute 50 bis 70 Tonnen. Dabei wurde die Arbeits- und Badspiegelhöhe von früher 0,6 bis 0,8 m auf über 1 m, in letzter Entwicklung sogar bis 1,3 m angehoben. Dies ergibt größere Verweilzeiten der Stahlschmelze und geringere Strömungsgeschwindigkeiten und somit bessere Abscheidemöglichkeiten von Verunreinigungen an das Abdeckpulver.During distribution channels of a two-strand slab line an average capacity of 10 years now 15 to 20 tons, this size is now 50 to 70 tons Metric tons. The working and bathroom mirror height was from earlier 0.6 to 0.8 m to over 1 m, in the last development even up 1.3 m raised. This results in longer dwell times Melting steel and lower flow velocities and thus better possibilities for separating contaminants the covering powder.
Die Stahlausbringung wird beim Stand der Technik entweder über Schieberregelungen oder über Stopfenregelung eingestellt. Beide Systeme funktionieren zufriedenstellend. Für den Fall des automatischen Angießens, was für breite Brammen wegen der Verteilung des ersten in die Kokille fließenden Stahles zumeist mit Schwierigkeiten verbunden ist, hat die Schieberregelung wegen der besseren Regelcharakteristik erhebliche Vorteile. Nachteile sind geringere Haltbarkeit der Schieberplatten gegenüber dem Stopfen sowie ein geringerer Reinheitsgrad der Stahlschmelze, weil über die Schieberspalten Luft angesaugt werden kann.The steel output is either over in the prior art Slider controls or set via plug control. Both systems work satisfactorily. In the case of automatic casting, what wide slabs because of the Distribution of the first steel flowing into the mold is usually associated with difficulties Slider control because of the better control characteristics significant benefits. Disadvantages are lower durability Slider plates opposite the stopper and a smaller one Degree of purity of the molten steel because of the slider gaps Air can be sucked in.
Die japanische Offenlegungsschrift 61-119358 (Anm.-Nr. 59-238244) beschreibt eine Verteilerrinne für ein kontinuierliches Gießverfahren einer Zweistrang-Brammenanlage. Die daraus ersichtliche Erfindung besteht darin, dass die vergleichsweise breite Verteilerrinne quer zur Längsrichtung in zwei durch eine Längswand getrennte Rinnenteile unterteilt ist. Von diesen dient eine der Aufnahme der aus Gießpfannen einströmenden Stahlschmelze, während die andere mit beiden Strängen zuordenbaren Gießrohren ausgestattet ist. In der die beiden Rinnenteile trennenden Längswand ist in Bodennähe eine Durchströmöffnung angeordnet, die eine kommunizierende Verbindung für die Stahlschmelze ergibt, wobei unerwünschte Verunreinigungen zurückgehalten werden, wodurch die Produktqualität verbessert wird.Japanese Patent Application Laid-Open No. 61-119358 (note no. 59-238244) describes a distribution channel for a continuous casting process of a two-strand slab line. The apparent invention is that the comparatively wide distribution channel across the longitudinal direction divided into two channel parts separated by a longitudinal wall is. One of these is used to hold the ladle incoming molten steel, while the other with both Pipe-assignable pouring tubes is equipped. In the The longitudinal wall separating the two channel parts is one near the floor Flow opening arranged that communicating Connection for the molten steel results, being undesirable Impurities are retained, causing the Product quality is improved.
Der Erfindung liegt die Aufgabe zugrunde, einen Verteilerrinnenwagen zur Aufnahme einer Zweistrang-Verteilerrinne, insbesondere für Dünnbrammen-Anlagen, derart zu verbessern und weiter auszubilden, dass mit ihr ein äußerst exaktes Ausrichten eines jeden Gießrohres in der Kokille eines Stranges ohne Veränderung der Position des Gießrohres für den zweiten Strang, und umgekehrt, zügig und millimetergenau durchgeführt werden kann, um einerseits einer Beschädigung von Gießrohr und/oder Kokille bei engen Platzverhältnissen in der Kokille und andererseits ein Auskühlen des Gießrohres bei zu langsamem Ausrichtvorgang zu vermeiden. Insbesondere soll die Anordnung des Rahmens am Verteilerrinnenwagen auch so beschaffen sein, dass eine visuelle überwachung von Gießrohr und Kokille während der Einführung des Gießrohres erleichtert wird.The invention has for its object a Distribution trough trolley to accommodate one Two-strand distribution channel, especially for Thin slab plants to improve and continue train that with her an extremely precise alignment of a each pouring tube in the mold of a strand without Change the position of the pouring tube for the second Strand, and vice versa, carried out quickly and with millimeter precision can be on the one hand damage to the pouring tube and / or mold in tight spaces in the mold and on the other hand cooling of the pouring tube if it is too slow Avoid alignment process. In particular, the arrangement of the frame on the distribution channel trolley should also be such that visual monitoring of the pouring tube and mold is facilitated during the introduction of the pouring tube.
Die Lösung der Aufgabe gelingt bei einem Verteilerrinnenwagen der im Oberbegriff von Anspruch 1 genannten Art mit der Erfindung dadurch, dass der Rahmen mit unterschiedlichen Längen seiner beiden Längsträger trapezförmig und relativ zu seiner Längsachse unsymmetrisch ausgebildet ist, und dass die Fahrschemel an dem längeren Längsträger Verstellantriebe mit Verstellgetrieben aufweisen, die ein Ausrichten eines Gießrohres in der Kokille des einen Stranges ohne Veränderung der Position des Gießrohres für die Kokille des anderen Stranges ermöglichen und umgekehrt.The task is solved with a distribution trolley the type mentioned in the preamble of claim 1 with the Invention in that the frame with different Lengths of its two longitudinal beams are trapezoidal and relative to its longitudinal axis is asymmetrical, and that the Subframe on the longer side member with adjustment drives Have actuators that align an Pouring tube in the mold of one strand without change the position of the pouring tube for the mold of the other Enable strands and vice versa.
Ermöglicht wird dieses vorteilhafte Ergebnis infolge der unsymmetrischen Ausbildung des Fahrgestells mit der sich daraus ergebenden Schrägstellung der Querträger bzw. des Fahrgestell-Rahmens, weil z. B. bei einer Verstellung eines Fahrschemels quer zur Fahrtrichtung der die Längsträger verbindende Querträger lediglich mit einer geringfügigen Änderung seiner Winkelstellung reagiert, wobei die zugeordnete Seite der Verteilerrinne in ihrer Mittelachslage korrigiert wird, ohne die Lage des gegenüberliegenden Gießrohres zu verändern.This advantageous result is made possible by the asymmetrical design of the chassis with the resulting oblique position of the cross member or Chassis frame because z. B. with an adjustment Subframe transverse to the direction of travel of the side members connecting cross member only with a minor Changing its angular position responds, the associated Corrected side of the tundish in its central axis position without the position of the opposite pouring tube change.
Mit Vorteil ist dabei vorgesehen, dass die Querträger in einem Winkel zwischen 30° und 60° zu den Längsträgern angeordnet sind, bevorzugt in einem Winkel von 45°.It is advantageously provided that the cross member in one Angles between 30 ° and 60 ° to the side members are, preferably at an angle of 45 °.
In weiterer Ausgestaltung ist vorgesehen, dass die Verteilerrinne einen in eine Abweiserrinne mündenden Notüberlauf besitzt, der infolge der erfindungsgemäßen Konzeption bevorzugt in der Mitte der Verteilerrinne angeordnet ist.In a further embodiment it is provided that the Distribution channel one ending in a deflector channel Has emergency overflow due to the invention Concept preferred in the middle of the distribution channel is arranged.

Das Fahrgestell des in der Figur 1 dargestellten Verteilerrinnenwagens (1) ist auf parallel beabstandeten Schienen (20) verfahrbar. Es kann beispielsweise zwischen einer Heizposition und einer Gießposition auf den Schienen (20) längsverfahren werden. Während eines Verfahrvorganges ist die darauf gelagerte Verteilerrinne (4) mit ihren beiden Gießrohren (2) bzw. (3) in einer gehobenen Position so anordenbar, dass die Gießrohre (2, 3) genügend hoch aus der Kokille herausgehoben und mit Freigang verfahrbar sind. Weiterhin ist es erforderlich, dass die Gießrohre (2, 3) der Verteilerrinne zur Einstellung beim Eintauchen in eine vergleichsweise schmale Parallel- oder Trichterkokille (5, 6) exakt positionierbar sind, weil infolge der engen Platzverhältnisse dieser Kokillen Relativbewegungen nur in äußerst engen Grenzen tolerierbar sind (Parallelkokille nicht dargestellt). Die Verteilerrinne (4) besitzt einen in eine Abweiserrinne (15) mündenden Notüberlauf (16).The chassis of the shown in Figure 1 Distribution trough carriage (1) is on parallel spaced Rails (20) can be moved. For example, it can be between a heating position and a pouring position on the rails (20) longitudinal process. During a traversing process the distribution channel (4) with its two mounted on it Pouring pipes (2) or (3) in a raised position like this can be arranged so that the pouring tubes (2, 3) are sufficiently high The mold is lifted out and can be moved with free access. It is also necessary that the pouring tubes (2, 3) of the Distribution channel for adjustment when immersed in a comparatively narrow parallel or funnel mold (5, 6) can be positioned exactly because of the narrow Space conditions of these molds only relative movements extremely narrow limits are tolerable (parallel mold not shown). The distribution channel (4) has one in one Deflector channel (15) opening emergency overflow (16).
Wie Figur 1 weiter zeigt, besitzt der Verteilerrinnenwagen (1) ein Fahrgestell mit einem Rahmen (9), der durch zwei Längsträger (7, 7') und diese verbindende Querträger (8, 8') ausgebildet ist, und dessen Ecken von je einem Fahrschemel (10) bzw. (11) mit je einem Schienenrad (12) und einem damit zusammenwirkenden Hubgetriebe (13) aufgenommen sind. Diese weisen je einen Auflagepunkt (17) für die Verteilerrinne (4) bzw. für den sie aufnehmenden Rahmen (9) auf.As FIG. 1 further shows, the distribution channel trolley (1) has a chassis with a frame (9) by two Side members (7, 7 ') and cross members (8, 8') connecting them is formed, and the corners of each of a subframe (10) or (11) each with a rail wheel (12) and one with it interacting lifting gear (13) are added. This each have a support point (17) for the distribution channel (4) or for the frame receiving them (9).
Erfindungsgemäß ist der Rahmen (9) mit unterschiedlichen Längen seiner beiden Längsträger (7, 7') trapezförmig und relativ zu seiner Längsachse (x-x) unsymmetrisch ausgebildet. Weiterhin weisen die Fahrschemel (10, 11) an dem längeren Längsträger (7) Verstellantriebe (14) mit Verstellgetrieben (18) auf, die ein Ausrichten eines Gießrohres (2) bzw.(3) in wenigstens einer Kokille (5) bzw. (6) eines Stranges ohne Veränderung der Position eines anderen Gießrohres (3) bzw. (2) für die Kokille (5) oder (6) des anderen Stranges ermöglichen und umgekehrt.According to the invention, the frame (9) is different Lengths of its two longitudinal beams (7, 7 ') and trapezoidal formed asymmetrically relative to its longitudinal axis (x-x). Furthermore, the subframes (10, 11) have the longer one Side member (7) adjustment drives (14) with adjustment gears (18) on the alignment of a pouring tube (2) or (3) in at least one mold (5) or (6) of a strand without Changing the position of another pouring tube (3) or (2) allow for the mold (5) or (6) of the other strand and vice versa.
Wie Figur 1 ferner zeigt, sind infolge der unsymmetrischen Anordnung die Querträger (8, 8') in einem Winkel zwischen 30° und 60° zu den Längsträgern (7) bzw. (7') angeordnet. Bevorzugt bilden die Querträger (8, 8') einen Winkel von 45° zu den Längsträgern (7, 7').As Figure 1 also shows, are due to the asymmetrical Arrange the crossbeams (8, 8 ') at an angle between 30 ° and 60 ° to the longitudinal beams (7) and (7 '). The cross members (8, 8 ') preferably form an angle of 45 ° to the side members (7, 7 ').
Figur 2 zeigt in perspektivischer Ansicht schräg- von oben einen Verteilerrinnenwagen (1) üblicher Bauart mit einem annähernd rechteckigen, symmetrisch zur Längsachse (x-x) ausgebildeten Rahmen (9). Dieser trägt, unterstützt durch vier Hubgetriebe (13), eine Verteilerrinne (4) mit zwei abfluss-geregelten Gießrohren. Der Verteilerrinnenwagen (1) ist auf parallelen Doppelschienen (20) in Richtung seiner Mittelachse (x-x) einerseits in eine Heizposition und andererseits in eine Gießposition verfahrbar. Bei der bekannten Konstruktion ist ein Ausrichten der Gießrohre relativ zur öffnung von Kokillen nicht möglich, weshalb die herkömmliche Bauart des Verteilerrinnenwagens nur mit Kokillen von Brammenanlagen toleriert werden kann, weil bei diesen genügend Freiraum zur Kompensation von größeren Positionstoleranzen vorhanden ist.Figure 2 shows a perspective view obliquely from above a distribution channel trolley (1) of conventional design with a approximately rectangular, symmetrical to the longitudinal axis (x-x) trained frame (9). Supported by four Hoist gear (13), a distributor channel (4) with two drain-regulated pouring pipes. The distribution channel wagon (1) is on parallel double rails (20) in the direction of Central axis (x-x) on the one hand in a heating position and on the other hand movable into a casting position. In the known construction is an alignment of the pouring tubes not possible relative to the opening of molds, which is why the Conventional design of the distribution trolley only with molds of slab plants can be tolerated because with these enough space to compensate for larger ones Positional tolerances exist.
