Definitions
- the invention relates to a strand guide of a steel continuous casting plant for producing a directly rollable strand, the strand guide having guide rails extending in the strand running direction with an interchangeable part facing the strand.
- the casting heat present in the cast strand is to be optimally used. Many efforts have been made to feed the strand emerging from a continuous casting plant directly or after it has been cut, to direct deformation or rolling.
- GB-PS 1188816 It is also known (GB-PS 1188816) to guide and extend the strand in the secondary cooling zone by means of metallic guide rails, the so-called “walking bars”. This achieves a support which prevents the strand from bulging, in particular from slabs, such guide rails resting on the surface of the strand, walking along a certain distance with the strand and then returning to their starting position.

- a guide rail is also known, in which a metallic part of the rail facing the strand is detachably fastened to a support part of the rail by means of bolts.
- the replaceable, metallic part has water channels for circulating cooling water. This should both cool the strand without the need for spray cooling and also protect the support part of the rail from heat.
- the strand guide according to the invention with guide rails, which have a ceramic, insulating part facing the strand surface, makes it possible, on the one hand, to guide or support the strand safely and, at the same time, to prevent undesired heat emission.
- Safe guiding and supporting is understood to mean that no harmful bulges occur on the strand, which still has a liquid core, as a result of the ferrostatic pressure. As is known, such bulges have negative effects on the cast product. The undesired heat emission is prevented due to the insulating effect of the ceramic part.
- the mean strand temperature i.e. H.
- the mean temperature above the strand thickness in the middle of the strand width is raised to normal rolling temperature, so that the strand can be heated without further heating, with the exception of the edges, i.e. Heat supply from the outside, which can be fed directly to further shaping, in particular by rolling. In exceptional cases, e.g. B. with wide slabs, an external heating of the edges may be appropriate.

- the necessary length of the insulating strand guide is approximately a quarter of the total strand guide length, which is known to have to extend from the lower mold end to the final solidification of the strand to prevent bulges.
- the insulating design of the strand guide achieves both an increase in the strand surface temperature and a reduction in the difference between this strand surface temperature and the core temperature of the strand. It is also important that the solidification time and thus the position of the bottom of the swamp, i. the location of the solidification of the strand is not significantly affected by the insulating effect of the ceramic part of the guide rail.
- the ceramic parts are advantageously connected to the support parts by means of metallic bolts, both the necessary counterpressure for ferrostatic pressure can be applied and the amount of heat dissipated can be predetermined within certain limits by the ratio of the ceramic surface on the strand to the metallic surface of the retaining bolts. Furthermore, the ceramic parts can be easily replaced by fastening with retaining bolts.

Abstract
Description
Die Erfindung betrifft eine Strangführung einer Stahlstranggiessanlage zur Herstellung eines direktwalzbaren Stranges, wobei die Strangführung in Stranglaufrichtung sich erstreckende Führungsschienen mit einem, dem Strang zugewandten, auswechselbaren Teil besitzt.The invention relates to a strand guide of a steel continuous casting plant for producing a directly rollable strand, the strand guide having guide rails extending in the strand running direction with an interchangeable part facing the strand.
Aufgrund wirtschaftlicher Überlegungen will man die im gegossenen Strang vorhandene Giesswärme optimal ausnützen. Viele Bestrebungen gingen dahin, den aus einer Stranggiessanlage austretenden Strang unmittelbar oder nach dem Trennen, einer direkten Verformung bzw. Verwalzung zuzuführen.Due to economic considerations, the casting heat present in the cast strand is to be optimally used. Many efforts have been made to feed the strand emerging from a continuous casting plant directly or after it has been cut, to direct deformation or rolling.
Es ist allgemein bekannt, den Strang zur Vermeidung von Wärmeverlusten in der Strangführung ganz oder teilweise zu isolieren oder ihn durch zusätzliche Heizelemente aufzuwärmen, um entweder eine bestimmte Walztemperatur zu erhalten oder einen gewünschten Temperaturausgleich herbeizuführen.It is generally known to completely or partially isolate the strand in order to avoid heat losses in the strand guide or to heat it up by means of additional heating elements in order either to maintain a specific rolling temperature or to bring about a desired temperature compensation.
Es ist ebenfalls bekannt (GB-PS 1188816), den Strang mittels metallischer Führungsschienen, den sog. «walking bars», in der Sekundärkühlzone zu führen und auszuziehen. Damit erreicht man eine, das Ausbauchen des Stranges, insbesondere von Brammen, verhindernde Abstützung, wobei solche Führungsschienen an der Strangoberfläche anliegen, mit dem Strang eine bestimmte Wegstrecke mitgehen und hernach wieder in ihre Ausgangsposition zurückkehren. Die metallischen Führungsschienen weisen Kühlkanäle in der Nähe ihrer Arbeitsflächen auf, um sowohl dem Strang Wärme zu entziehen, als-auch die Schienen selbst zu kühlen.It is also known (GB-PS 1188816) to guide and extend the strand in the secondary cooling zone by means of metallic guide rails, the so-called “walking bars”. This achieves a support which prevents the strand from bulging, in particular from slabs, such guide rails resting on the surface of the strand, walking along a certain distance with the strand and then returning to their starting position. The metallic guide rails have cooling channels in the vicinity of their work surfaces in order to both extract heat from the strand and also to cool the rails themselves.
Es ist aus der US-A-3688833, welche den Oberbegriff des Anspruchs 1 bildet, auch eine Führungsschiene bekannt, bei der ein dem Strang zugewandter metallischer Teil der Schiene mittels Bolzen lösbar an einem Trägerteil der Schiene befestigt ist. Dabei weist der auswechselbare, metallische Teil Wasserführungen für zirkulierendes Kühlwasser auf. Dadurch sollte sowohl der Strang ohne weitere Notwendigkeit einer Sprühkühlung gekühlt als auch der Trägerteil der Schiene vor Wärme geschützt werden.From US-A-3688833, which forms the preamble of claim 1, a guide rail is also known, in which a metallic part of the rail facing the strand is detachably fastened to a support part of the rail by means of bolts. The replaceable, metallic part has water channels for circulating cooling water. This should both cool the strand without the need for spray cooling and also protect the support part of the rail from heat.
Es ist Aufgabe der Erfindung, eine Strangführung, insbesondere für Brammenstränge, zu schaffen, die ein sicheres Führen eines Stranges mit noch flüssigem Kern unter möglichst geringen Wärmeverlusten erlaubt, um ein direktes Weiterverwalzen bei entsprechender Walztemperatur, ohne zusätzliche Aufheizung durch Wärmequellen von aussen zu ermöglichen. Weiter soll eine Verzunderung des Stranges in der Strangführung vermieden sowie eventuell bereits entstandener Zunder vor Eintritt in diesen Teil der Strangführung entfernt werden.It is an object of the invention to provide a strand guide, in particular for slab strands, which allows a strand with a still liquid core to be guided safely with as little heat loss as possible, in order to enable direct rolling at the appropriate rolling temperature without additional heating from outside by heat sources. Furthermore, scaling of the strand in the strand guide is to be avoided and any scale that has already formed should be removed before entering this part of the strand guide.
Gelöst wird diese Aufgabe erfindungsgemäss durch die in dem Patentanspruch 1 genannten kennzeichnenden Merkmale.This object is achieved according to the invention by the characterizing features mentioned in patent claim 1.
Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen genannt.Advantageous further developments and refinements of the invention are mentioned in the further claims.
Durch die erfindungsgemässe Strangführung mit Führungsschienen, die einen, der Strangoberfläche zugewandten keramischen, isolierenden Teil aufweisen, ist es möglich, den Strang einerseits sicher zu führen bzw. zu stützen und gleichzeitig eine unerwünschte Wärmeabgabe zu verhindern. Unter sicherem Führen und Stützen wird verstanden, dass an dem, noch einen flüssigen Kern aufweisenden Strang keine schädlichen Ausbauchungen infolge des ferrostatischen Druckes auftreten. Solche Ausbauchungen haben, wie bekannt, negative Auswirkungen auf das Gussprodukt. Die unerwünschte Wärmeabgabe wird wegen der isolierenden Wirkung des keramischen Teils verhindert. Durch diese Isolierung des Stranges innerhalb der Strangführung wird die mittlere Strangtemperatur, d. h. die mittlere Temperatur über die Strangdicke in der Mitte der Strangbreite auf normale Walztemperatur angehoben, so dass der Strang ohne weitere Erwärmung, mit Ausnahme an den Kanten, durch Aufwärmöfen, d.h. Wärmezufuhr von aussen, der direkten Weiterverformung, insbesondere durch Walzen, zugeführt werden kann. In Ausnahmefällen, z. B. bei breiten Brammen, kann eine äusserliche Aufwärmung der Kanten angebracht sein. Vor seiner Verwalzung kann der Strang mittels üblicher Trennaggregate, z. B. durch Brenner, nach seiner vollständigen Erstarrung getrennt werden.The strand guide according to the invention with guide rails, which have a ceramic, insulating part facing the strand surface, makes it possible, on the one hand, to guide or support the strand safely and, at the same time, to prevent undesired heat emission. Safe guiding and supporting is understood to mean that no harmful bulges occur on the strand, which still has a liquid core, as a result of the ferrostatic pressure. As is known, such bulges have negative effects on the cast product. The undesired heat emission is prevented due to the insulating effect of the ceramic part. By isolating the strand within the strand guide, the mean strand temperature, i.e. H. the mean temperature above the strand thickness in the middle of the strand width is raised to normal rolling temperature, so that the strand can be heated without further heating, with the exception of the edges, i.e. Heat supply from the outside, which can be fed directly to further shaping, in particular by rolling. In exceptional cases, e.g. B. with wide slabs, an external heating of the edges may be appropriate. Before it is rolled, the strand can be separated using conventional separation units, e.g. B. by burner, after its complete solidification.
Die notwendige Länge der isolierenden Strangführung beträgt etwa ein Viertel der gesamten Strangführungslänge, die bekanntlich zur Verhinderung der Ausbauchungen vom unteren Kokillenende bis zur Enderstarrung des Stranges reichen muss.The necessary length of the insulating strand guide is approximately a quarter of the total strand guide length, which is known to have to extend from the lower mold end to the final solidification of the strand to prevent bulges.
Es hat sich gezeigt, dass durch die isolierende Ausgestaltung der Strangführung sowohl eine Erhöhung der Strangoberflächentemperatur als auch eine Verringerung des Unterschiedes dieser Strangoberflächentemperatur zur Kerntemperatur des Stranges erzielt wird. Wesentlich ist dabei auch, dass die Erstarrungszeit und damit die Lage der Sumpfspitze, d. i. der Ort der Durcherstarrung des Stranges, durch die isolierende Wirkung des keramischen Teils der Führungsschiene nicht wesentlich beeinträchtigt wird.It has been shown that the insulating design of the strand guide achieves both an increase in the strand surface temperature and a reduction in the difference between this strand surface temperature and the core temperature of the strand. It is also important that the solidification time and thus the position of the bottom of the swamp, i. the location of the solidification of the strand is not significantly affected by the insulating effect of the ceramic part of the guide rail.
Da die keramischen Teile mit den Stützteilen vorteilhaft über metallische Bolzen verbunden sind, kann sowohl der notwendige Gegendruck zum ferrostatischen Druck aufgebracht werden, als auch die abgeführte Wärmemenge durch das Verhältnis der am Strang anliegenden keramischen Oberfläche zur metallischen Oberfläche der Haltebolzen in gewissen Grenzen vorbestimmt werden. Ferner ist durch die Befestigung mit Haltebolzen eine leichte Auswechselbarkeit der Keramikteile gegeben. Gegebenenfalls kann der metallische Stützkörper wassergekühlt sein, wodurch die Wärmeabfuhr ebenfalls beeinflusst werden kann.Since the ceramic parts are advantageously connected to the support parts by means of metallic bolts, both the necessary counterpressure for ferrostatic pressure can be applied and the amount of heat dissipated can be predetermined within certain limits by the ratio of the ceramic surface on the strand to the metallic surface of the retaining bolts. Furthermore, the ceramic parts can be easily replaced by fastening with retaining bolts. If necessary, the metallic support body can be water-cooled, whereby the heat dissipation can also be influenced.
Die direkte Verwalzung wird auch dadurch erleichtert, dass der Strang vor Eintritt in die Strangführung mit den Führungsschienen entzundert wird und im weiteren Strangverlauf der Zutritt von Luftsauerstoff durch Inertgas verhindert wird.Direct rolling is also facilitated by descaling the strand with the guide rails before entering the strand guide and preventing the entry of atmospheric oxygen by inert gas in the further course of the strand.
In den Zeichnungen ist die Erfindung beispielhaft dargestellt, es zeigt:
- Fig. 1 schematisch eine Stranggiessanlage, die die erfindungsgemässe Strangführung aufweist,
- Fig.2 einen Querschnitt nach der Linie 11-11 der Fig. sowie
- Fig. einen Längsschnitt nach der Linie 111-111 der Fig.1.
- 1 schematically shows a continuous casting installation which has the strand guide according to the invention,
- 2 shows a cross section along the line 11-11 of FIG
- Fig. A longitudinal section along the line 111-111 of Fig.1.
In Fig. ist, nachfolgend einer Kokille (1), einem aus Rollen (2, 2') bestehenden Teil einer Strangführung (3) und einem Treib-Richtaggregat (4) ein Strangführungsteil (5) bestehend aus Führungsschienen (6) angeordnet. Bei der dargestellten Bodenanlage zum Giessen von Brammen erstrecken sich diese ausförderseitig im horizontalen Strangführungsteil befindlichen Führungsschienen (6) in Längsrichtung des gegossenen Stranges (7) und sind, einander gegenüberliegend, jeweils der Stranginnen- bzw. Strangaussenseite zugeordnet. Je nach Strangbreite sind jeweils eine oder mehrere Schienen nebeneinander angeordnet, die, wie an sich bekannt, durch wechselweises Anliegen den einen flüssigen Kern aufweisenden Strang stützen und führen. Im gezeigten Beispiel, Fig.2, sind pro Strangseite sechs Schienen über die Breite der Bramme von 1600mm vorgesehen. Durch die in Längsrichtung über mehrere Meter verlaufende Abstützung sowie die enge Anordnung der Führungsschienen über die Strangbreite ist die Gefahr eines schädlichen Ausbauchens der Bramme nicht mehr gegeben. Im Beispiel sind zwei sich hintereinander folgende Zonen (5', 5") von Führungsschienen von je ca. 5m Länge vorgesehen.In Fig., A mold guide (5) consisting of guide rails (6) is arranged below a mold (1), a part of a strand guide (3) consisting of rollers (2, 2 ') and a drive-straightening unit (4). In the floor system for casting slabs shown, these guide rails (6) located on the discharge side in the horizontal strand guide part extend in the longitudinal direction of the cast strand (7) and are, opposite one another, assigned to the inside or outside of the strand. Depending on the strand width, one or more rails are arranged side by side, which, as is known per se, support and guide the strand which has a liquid core by alternating contact. In the example shown, Fig.2, six rails across the width of the slab of 1600mm are provided on each strand side. The support extending several meters in the longitudinal direction and the narrow arrangement of the guide rails across the strand width means that there is no longer any danger of the slab being bulged. In the example, two successive zones (5 ', 5 ") of guide rails, each about 5 m long, are provided.
Wie aus den Figuren 2 und 3 ersichtlich ist, besteht eine Führungsschiene (6) im wesentlichen aus einem, dem Strang (7) zugewandten, keramischen Teil (10), der mittels metallischer Bolzen (11) oder dergleichen an einem metallischen Tragteil (12) befestigt ist. Die Schienen werden über einen nicht gezeichneten Mechanismus, entlang der Strangbreite gesehen, abwechselnd an den Strang gepresst, mit diesem in Stranglaufrichtung mitbewegt, abgehoben und zurückgeführt, worauf dieser Zyklus wieder von neuem beginnt. Vorrichtungen zur Durchführung dieser Bewegung sind aus dem Stand der Technik hinlänglich bekannt und sind nicht Gegenstand der vorliegenden Erfindung.As can be seen from FIGS. 2 and 3, a guide rail (6) essentially consists of a ceramic part (10) facing the strand (7), which is attached to a metal support part (12) by means of metallic bolts (11) or the like. is attached. The rails are alternately pressed against the strand by means of a mechanism (not shown), seen along the strand width, moved with it in the strand running direction, lifted and returned, whereupon this cycle starts again. Devices for performing this movement are well known from the prior art and are not the subject of the present invention.
Der keramische Teil (10) ist nach Abnützung bzw. bei Bedarf durch Lösen der Bolzen (11) auswechselbar.The ceramic part (10) can be replaced after wear or if necessary by loosening the bolts (11).
Während bei dem aus Rollen bestehenden Teil der Strangführung anfänglich eine möglichst starke Kühlung mittels Sprühdüsen (13), gegebenenfalls auch mittels Wasser-Luftdüsen, des Stranges (7) erfolgt, um die Sumpflänge möglichst klein zu halten, ist der keramische Teil (10) der Schienenführung wärmeisolierend und verhindert dadurch eine unerwünschte Abkühlung der Bramme und bewirkt einen Temperaturausgleich innerhalb der einzelnen Strangbereiche.While the part of the strand guide consisting of rollers is initially cooled as much as possible by means of spray nozzles (13), optionally also by means of water-air nozzles, of the strand (7) in order to keep the length of the sump as small as possible, the ceramic part (10) is the Rail guiding is heat-insulating and thus prevents the slab from cooling down undesirably and ensures temperature compensation within the individual strand areas.
Die erreichte Strangoberflächentemperatur ist mit ca. 1200 °C höher und die Strangschalenfestigkeit niedriger als bei herkömmlichen Stranggiessanlagen. Dies würde geringere Stützabstände erfordern, um Innenfehler im Strang zu vermeiden. Diese sind jedoch durch Rollen nicht erzielbar.The strand surface temperature reached is approx. 1200 ° C higher and the strand shell strength is lower than in conventional continuous casting plants. This would require smaller support spacings to avoid internal defects in the line. However, these cannot be achieved by rolling.
Der keramische Teil (10) kann aus einer gegossenen feuerfesten Masse bestehen. Der metallische Tragteil (12) ist durch Kühlkanäle (15) wassergekühlt.The ceramic part (10) can consist of a cast refractory mass. The metallic support part (12) is water-cooled by cooling channels (15).
Bekanntlich stört der durch Reaktion des Luftsauerstoffes mit der Stahloberfläche entstehende Zunder. Vor Eintritt in die erste Zone (5') der Führungsschienen (6) ist daher eine Entzunderungsstation (16) mit Hochdruckspritzdüsen vorgesehen. Wie in Fig. 2 nur für eine Seite des Stranges gezeichnet, wird im Bereich dieser Zonen (5', 5") durch Inertgas, das über die Leitung (17) zugeführt wird sowie über eine seitliche Abdichtung (20), der Zutritt von Luftsauerstoff unterbunden.As is well known, the scale caused by the reaction of atmospheric oxygen with the steel surface interferes. A descaling station (16) with high-pressure spray nozzles is therefore provided before entry into the first zone (5 ') of the guide rails (6). As shown in Fig. 2 for only one side of the strand, the entry of atmospheric oxygen is in the area of these zones (5 ', 5 ") by inert gas, which is supplied via the line (17) and via a lateral seal (20) prevented.
Nach dem Trennen des nun vollständig erstarrten Stranges in einer Schneidstation (18) können die Strangabschnitte direkt einem schematisch dargestellten Walzwerk (19) zugeführt werden.After the strand which has now completely solidified is cut in a cutting station (18), the strand sections can be fed directly to a schematically illustrated rolling mill (19).
