Definitions
- the invention relates to a horizontal continuous casting device with a storage vessel to which the horizontal continuous casting mold is interchangeably attached by means of a sealing nozzle block, the horizontal continuous casting mold adjacent to the nozzle block having a length section of a mold tube made of a heat-conducting material, to which a mold tube length section made of the less heat-conducting material is connected , which is arranged in a guide tube made of steel, which is surrounded by coolant on the outside.
- Such a horizontal continuous casting device is known from DE-OS 20 25 764.
- the guide tube has the task of keeping the insert from the heat less highly conductive material, to secure it and to enable the heat transfer from the cast strand surface through the material to the cooling water.
- the less heat-conducting material mostly consists of graphite.
- the heat is therefore removed from the cast strand through the graphite and through the guide tube to the coolant, such as cooling water.
- Graphite which is in contact with a cast strand made of metal, in particular steel, is used because of the "self-lubrication" and other advantageous properties. These characteristic values are particularly important for a steel guide tube.
- the mold tube length section following the nozzle block and upstream of the guide tube usually consists of copper and is referred to as a copper module.
- the cast strand shell is formed with every drawing process and intermittently welded to the cast strand.
- strong cooling as guaranteed by copper, must initially be achieved.
- the growing cast strand shell forms in itself an increasing resistance to the heat transfer, so that viewed in the casting direction, a material with a lower thermal conductivity, such as graphite, is sufficient for cooling.
- Such a graphite tube is now pressed into the guide tube in order to provide sufficient stability and cooling options.
- the guide tube is cooled with water from the outside.
- the guide tube was made from copper or from structural steel (unalloyed or low-alloy structural steel). However, problems arise with both copper and structural steel.
- Copper is disadvantageous because of the high thermal conductivity with low material properties and the high elasticity.
- the high thermal conductivity means that structural steel is cooled very abruptly, which can lead to stresses in the thin cast shell and thus to internal cracks.
- the high elasticity and the low strength of the material copper is disadvantageous because a guide tube made of it deforms, which also causes qualitative disadvantages for the cast strand.
- the material price for copper is very high.
- Structural steel is usually used in thinner wall thicknesses than copper in order to compensate for the low thermal conductivity.
- the stability of the guide tube suffers if the wall thickness is too small.
- a major disadvantage of structural steel guide tubes is the corrosion resistance of the material. As a result, the properties relating to cooling can change locally.
- Corrosion also causes sealing problems, since wear of the guide tube also occurs at the sealing points. Such signs of wear can require a replacement of the guide tube within a short time, so that due to the considerably shorter service life there are hardly any cost advantages compared to a guide tube made of copper.
- the low strength of the material, like copper, can also lead to disadvantageous deformations of the guide tube.
- the invention is therefore based on the object of improving the properties of the guide tube with respect to shape, durability, economy with sufficient thermal conductivity.
- the stated object is achieved according to the invention at the outset by virtue of the fact that the length of the mold tube made of less heat-conducting material is arranged within such a guide tube which is made of corrosion-resistant, heat-resistant steel with a thermal conductivity of 20 to 40 W / mK.
- the correspondingly more expensive production compared to a guide tube made of structural steel is more than offset by the significantly increased durability, which is included in the total costs, as has been shown by extensive tests.
- the wall thickness of the guide tube is 5 to 20 mm.
- the horizontal continuous casting device has a storage vessel (1) with an outlet (2).
- the outlet (2) is essentially formed by a nozzle block (3).
- the horizontal continuous casting mold (5) adjoining the nozzle block (3) in the continuous casting direction (4) is connected in a sealed manner to the outlet (2) via the nozzle block (3).
- the horizontal continuous casting mold (5) has a mold tube (6) which consists of a heat-conducting first mold tube length section (7) (e.g. made of copper) and a heat-less conductive second mold tube length section (8) (e.g. made of graphite).
- the length of the mold tube sections (7 and 8) are sealed together at their joint (9).
- the mold tube length section (8) (e.g. made of graphite) is pressed into a guide tube (10).
- Cooling channels (12 and 13) are formed between the housing (11) and the guide tube (10), so that the coolant flow from the coolant inlet (14) around a sleeve (15) is circulated through a coolant outlet (16), whereby the coolant flows are separated by an annular wall (17).
- the guide tube (10) is resiliently held in the axial direction by means of a housing cover (18). Here the guide tube (10) against a collar (7a) of the mold tube length section (7), which itself is connected to the housing (11).
- the guide tube (10) consists of corrosion-resistant steel, so that the cooling water does no damage from the outside.
- the heat-resistant property of the guide tube (10) makes it possible to absorb a significant temperature jump from the cast strand shell temperature (approx. 1300 to 1500 degrees C) to the coolant temperature. With a thickness of 5 to 20 mm, a thermal conductivity of 20 to 40 W / m.K is favorable. Given the given values, it is advantageously possible to reduce the length of the horizontal continuous casting mold (9) to approximately 700 mm.

Abstract
Description
Die Erfindung betrifft eine Horizontalstranggießvorrichtung mit einem Vorratsgefäß, an das die Horizontalstranggießkokille mittels eines abdichtenden Düsensteins auswechselbar angesetzt ist, wobei die Horizontalstranggießkokille an den Düsenstein angrenzend einen Längenabschnitt eines Kokillenrohrs aus einem Wärme hochleitenden Werkstoff aufweist, auf den ein Kokillenrohrlängenabschnitt aus die Wärme weniger hochleitendem Werkstoff anschließt, der in einem Führungsrohr aus Stahl angeordnet ist, das außen von Kühlmittel umströmt ist.The invention relates to a horizontal continuous casting device with a storage vessel to which the horizontal continuous casting mold is interchangeably attached by means of a sealing nozzle block, the horizontal continuous casting mold adjacent to the nozzle block having a length section of a mold tube made of a heat-conducting material, to which a mold tube length section made of the less heat-conducting material is connected , which is arranged in a guide tube made of steel, which is surrounded by coolant on the outside.
Eine derartige Horizontalstranggießvorrichtung ist aus der DE-OS 20 25 764 bekannt.Such a horizontal continuous casting device is known from DE-OS 20 25 764.
In der Horizontalstranggießvorrichtung bzw. in der Horizontalstranggießkokille hat das Führungsrohr die Aufgabe, den Einsatz aus die Wärme weniger hochleitendem Werkstoff zu halten, zu sichern und die Wärmeabfuhr von der Gußstrangoberfläche durch den Werkstoff an das Kühlwasser zu ermöglichen. Der die Wärme weniger hochleitende Werkstoff besteht meistens aus Graphit. Die Wärmeabfuhr erfolgt daher von dem Gußstrang durch den Graphit und durch das Führungsrohr hindurch an das Kühlmittel, wie z.B. Kühlwasser. Graphit, der im Kontakt mit einem Gußstrang aus Metall, insbesondere aus Stahl, steht, wird wegen der "Selbstschmierung" und anderer vorteilhafter Eigenschaften verwendet. Diese Kennwerte sind bei einem Führungsrohr aus Stahl besonders wichtig. Der dem Düsenstein nachfolgende, dem Führungsrohr vorgeordnete Kokillenrohrlängenabschnitt besteht meist aus Kupfer und wird als Kupfermodul bezeichnet. In diesem Kupfermodul wird die Gußstrangschale bei jedem Ziehvorgang gebildet und intermittierend mit dem Gußstrang verschweißt. Zur Stabilität der Strangschale muß anfangs eine starke Kühlung, wie sie Kupfer gewährleistet, erreicht werden. Die wachsende Gußstrangschale bildet in sich selbst einen größerwerdenden Widerstand gegen den Wärmedurchgang, so daß in Gießrichtung gesehen zur Kühlung ein Werkstoff mit geringerer Wärmeleitfähigkeit, wie z.B. Graphit, ausreicht. Ein solches Graphitrohr ist nunmehr in das Führungsrohr eingepreßt, um eine ausreichende Stabilität und Kühlungsmöglichkeit zu schaffen. Außerdem wird das Führungsrohr von außen mit Wasser gekühlt. In der Vergangenheit wurde das Führungsrohr aus Kupfer oder auch aus Baustahl (unlegierter oder niedriglegierter Baustahl) hergestellt. Sowohl bei dem Werkstoff Kupfer als auch bei dem Werkstoff Baustahl treten jedoch Probleme auf. Kupfer ist nachteilig wegen der hohen Wärmeleitfähigkeit bei niedrigen Materialkennwerten und der hohen Elastizität. Durch die hohe Wärmeleitfähigkeit wird hingegen Baustahl sehr schroff gekühlt, was zu Spannungen in der dünnen Gußstrangschale und damit zu Innenrissen führen kann. Die hohe Elastizität sowie die geringe Festigkeit des Werkstoffes Kupfer ist nachteilig, weil sich ein daraus gefertigtes Führungsrohr verformt, was ebenfalls qualitative Nachteile für den Gußstrang bewirkt. Außerdem liegt der Materialpreis bei Kupfer sehr hoch. Baustahl wird üblicherweise zwar in dünneren Wandstärken als Kupfer eingesetzt, um die geringe Wärmeleitfähigkeit zu kompensieren. Jedoch leidet die Stabilität des Führungsrohres bei zu geringen Wandstärken. Ein wesentlicher Nachteil von Baustahl-Führungsrohren ist jedoch die Korrosionsfähigkeit des Werkstoffes. Dadurch können sich örtlich die Eigenschaften in bezug auf die Kühlung verändern. Ferner treten durch Korrosion auch Abdichtprobleme auf, da der Verschleiß des Führungsrohres auch an den Dichtstellen auftritt. Derartige Verschleißerscheinungen können innerhalb kurzer Zeit eine Auswechslung des Führungsrohres bedingen, so daß aufgrund der erheblich kürzeren Lebensdauer kaum noch Kostenvorteile gegenüber einem Führungsrohr aus Kupfer auftreten.In the horizontal continuous casting device or in the horizontal continuous casting mold, the guide tube has the task of keeping the insert from the heat less highly conductive material, to secure it and to enable the heat transfer from the cast strand surface through the material to the cooling water. The less heat-conducting material mostly consists of graphite. The heat is therefore removed from the cast strand through the graphite and through the guide tube to the coolant, such as cooling water. Graphite, which is in contact with a cast strand made of metal, in particular steel, is used because of the "self-lubrication" and other advantageous properties. These characteristic values are particularly important for a steel guide tube. The mold tube length section following the nozzle block and upstream of the guide tube usually consists of copper and is referred to as a copper module. In this copper module, the cast strand shell is formed with every drawing process and intermittently welded to the cast strand. To ensure the stability of the strand shell, strong cooling, as guaranteed by copper, must initially be achieved. The growing cast strand shell forms in itself an increasing resistance to the heat transfer, so that viewed in the casting direction, a material with a lower thermal conductivity, such as graphite, is sufficient for cooling. Such a graphite tube is now pressed into the guide tube in order to provide sufficient stability and cooling options. In addition, the guide tube is cooled with water from the outside. In the past, the guide tube was made from copper or from structural steel (unalloyed or low-alloy structural steel). However, problems arise with both copper and structural steel. Copper is disadvantageous because of the high thermal conductivity with low material properties and the high elasticity. On the other hand, the high thermal conductivity means that structural steel is cooled very abruptly, which can lead to stresses in the thin cast shell and thus to internal cracks. The high elasticity and the low strength of the material copper is disadvantageous because a guide tube made of it deforms, which also causes qualitative disadvantages for the cast strand. In addition, the material price for copper is very high. Structural steel is usually used in thinner wall thicknesses than copper in order to compensate for the low thermal conductivity. However, the stability of the guide tube suffers if the wall thickness is too small. A major disadvantage of structural steel guide tubes is the corrosion resistance of the material. As a result, the properties relating to cooling can change locally. Corrosion also causes sealing problems, since wear of the guide tube also occurs at the sealing points. Such signs of wear can require a replacement of the guide tube within a short time, so that due to the considerably shorter service life there are hardly any cost advantages compared to a guide tube made of copper.
Bei dünnen Wanddicken des Führungsrohres aus Baustahl kann es überdies durch die geringe Festigkeit des Werkstoffes ebenfalls wie bei Kupfer zu nachteiligen Verformungen des Führungsrohres kommen.In the case of thin wall thicknesses of the guide tube made of structural steel, the low strength of the material, like copper, can also lead to disadvantageous deformations of the guide tube.
Der Erfindung liegt daher die Aufgabe zugrunde, die Eigenschaften des Führungsrohres bezüglich Formtreue, Haltbarkeit, Wirtschaftlichkeit bei ausreichender Wärmeleitfähigkeit zu verbessern.The invention is therefore based on the object of improving the properties of the guide tube with respect to shape, durability, economy with sufficient thermal conductivity.
Die gestellte Aufgabe wird bei der eingangs bezeichneten Gattung erfindungsgemäß dadurch gelöst, daß der Kokillenrohrlängenabschnitt aus die Wärme weniger hochleitendem Werkstoff innerhalb eines solchen Führungsrohres angeordnet ist, das aus korrosionsbeständigem, warmfestem Stahl mit einer Wärmeleitfähigkeit von 20 bis 40 W/m.K hergestellt ist. Die entsprechend teurere Herstellung gegenüber einem Führungsrohr aus Baustahl wird durch die in die Gesamtkosten eingehende wesentlich erhöhte Haltbarkeit mehr als aufgefangen, wie sich durch eingehende Versuche gezeigt hat. Außerdem bestehen folgende Vorteile:
- höhere Warmfestigkeit (gleichmäßige Strangkühlung durch erhöhte Kokillenform-Stabilität),
- keine Korrosion an der Wasserseite (und damit Gewährleistung einer gesteuerten Kühlleistung über die gesamte Standzeit),
- höhere Kontakttemperatur des die Wärme weniger hochleitenden Werkstoffes - Graphit - und damit erhöhte Durchschnittstemperatur (keine übermäßige Strangschalenkühlung),
- Vergleichmäßigung der Strangoberflächenkühlung bzw. -temperaturen (weniger Spannungen und Fehler, wie z.B. Innenrisse),
- kein "Strangatmen",
- leichterer Wechsel des Graphiteinsatzes durch formstabiles und glatteres Führungsrohr,
- und qualitätsgerechte Verminderung der Kokillenbereichskühlung (geringere Wärmeleitfähigkeit des Führungsrohres).The stated object is achieved according to the invention at the outset by virtue of the fact that the length of the mold tube made of less heat-conducting material is arranged within such a guide tube which is made of corrosion-resistant, heat-resistant steel with a thermal conductivity of 20 to 40 W / mK. The correspondingly more expensive production compared to a guide tube made of structural steel is more than offset by the significantly increased durability, which is included in the total costs, as has been shown by extensive tests. There are also the following advantages:
- higher heat resistance (uniform strand cooling due to increased mold stability),
- no corrosion on the water side (and thus guarantee a controlled cooling capacity over the entire service life),
- higher contact temperature of the less heat-conducting material - graphite - and thus increased average temperature (no excessive strand shell cooling),
- equalization of the strand surface cooling or temperatures (less stresses and errors, such as internal cracks),
- no "strand breathing",
- easier replacement of the graphite insert due to the dimensionally stable and smoother guide tube,
- and quality-related reduction of the mold area cooling (lower thermal conductivity of the guide tube).
Von Vorteil ist außerdem, daß die Wanddicke des Führungsrohres 5 bis 20 mm beträgt.It is also advantageous that the wall thickness of the guide tube is 5 to 20 mm.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.
Die einzige Figur der Zeichnung zeigt einen Längsschnitt durch das Vorratsgefäß mit in Stranglaufrichtung folgender Horizontalstranggießkokille.The only figure in the drawing shows a longitudinal section through the storage vessel with the horizontal continuous casting mold following in the direction of the strand.
Die Horizontalstranggießvorrichtung weist ein Vorratsgefäß (1) auf, mit einem Auslaß (2). Der Auslaß (2) wird im wesentlichen duch einen Düsenstein (3) gebildet. Die an den Düsenstein (3) in Stranggießrichtung (4) anschließende Horizontalstranggießkokille (5) ist über den Düsenstein (3) abgedichtet an den Auslaß (2) angeschlossen.The horizontal continuous casting device has a storage vessel (1) with an outlet (2). The outlet (2) is essentially formed by a nozzle block (3). The horizontal continuous casting mold (5) adjoining the nozzle block (3) in the continuous casting direction (4) is connected in a sealed manner to the outlet (2) via the nozzle block (3).
Die Horizontalstranggießkokille (5) weist ein Kokillenrohr (6) auf, das aus einem die Wärme hochleitenden ersten Kokillenrohrlängenabschnitt (7) (z.B. aus Kupfer hergestellt) und aus einem die Wärme weniger hochleitenden zweiten Kokillenrohrlängenabschnitt (8) (z.B. aus Graphit hergestellt) besteht. Die Kokillenrohrlängenabschnitte (7 und 8) sind an ihrer Stoßstelle (9) dichtend aneinandergesetzt. Der Kokillenrohrlängenabschnitt (8) (z.B. aus Graphit) ist in ein Führungsrohr (10) eingepreßt. Zwischen dem Gehäuse (11) und dem Führungsrohr (10) sind Kühlkanäle (12 bzw. 13) gebildet, so daß die Kühlmittelströmung vom Kühlmitteleintritt (14) um eine Hülse (15) herum durch einen Kühlmittelaustritt (16) im Kreislauf geführt wird, wobei die Kühlmittelströmungen durch eine Ringwand (17) getrennt sind.The horizontal continuous casting mold (5) has a mold tube (6) which consists of a heat-conducting first mold tube length section (7) (e.g. made of copper) and a heat-less conductive second mold tube length section (8) (e.g. made of graphite). The length of the mold tube sections (7 and 8) are sealed together at their joint (9). The mold tube length section (8) (e.g. made of graphite) is pressed into a guide tube (10). Cooling channels (12 and 13) are formed between the housing (11) and the guide tube (10), so that the coolant flow from the coolant inlet (14) around a sleeve (15) is circulated through a coolant outlet (16), whereby the coolant flows are separated by an annular wall (17).
Das Führungsrohr (10) ist in axialer Richtung mittels eines Gehäusedeckels (18) federnd gehalten. Hierbei liegt das Führungsrohr (10) gegen einen Bund (7a) des Kokillenrohrlängenabschnittes (7) an, der selbst mit dem Gehäuse (11) verbunden ist.The guide tube (10) is resiliently held in the axial direction by means of a housing cover (18). Here the guide tube (10) against a collar (7a) of the mold tube length section (7), which itself is connected to the housing (11).
Das Führungsrohr (10) besteht aus korrosionsbeständigem Stahl, so daß das Kühlwasser von außen keinen Schaden anrichtet. Das Auswechseln des Graphiteinsatzes, d.h. des Kokillenrohrlängenabschnittes (8), wird außerdem nicht durch korrodierte Oberflächen behindert. Die Warmfesteigenschaft des Führungsrohres (10) gestattet, einen erheblichen Temperatursprung von der Gußstrangschalentemperatur (ca. 1300 bis 1500 Grad C) bis zur Kühlmitteltemperatur aufzufangen. Bei einer Dicke von 5 bis 20 mm ist eine Wärmeleitfähigkeit von 20 bis 40 W/m.K günstig. Bei den gegebenen Werten ist es vorteilhafterweise möglich, die Länge der Horizontalstranggießkokille (9) bis auf ca. 700 mm zu vermindern.The guide tube (10) consists of corrosion-resistant steel, so that the cooling water does no damage from the outside. The replacement of the graphite insert, i.e. the mold tube length section (8), is also not hindered by corroded surfaces. The heat-resistant property of the guide tube (10) makes it possible to absorb a significant temperature jump from the cast strand shell temperature (approx. 1300 to 1500 degrees C) to the coolant temperature. With a thickness of 5 to 20 mm, a thermal conductivity of 20 to 40 W / m.K is favorable. Given the given values, it is advantageously possible to reduce the length of the horizontal continuous casting mold (9) to approximately 700 mm.
