Definitions
- the present invention relates to the casting of metals into fusion, and more particularly to the vertical continuous casting of parts of metal, in particular of tubes, of cast iron. Although it applies to casting of different types of metal parts, it is particularly advantageous for casting thin cast iron tubes.
- thin tubes applies to a tube with a low thickness / diameter ratio, less than 10 percent, rather than the thickness considered in isolation.
- the invention relates more precisely to a casting machine vertical continuous, according to the preamble of claim 1, which is based on WO-A-94/26 444, along a vertical axis of extraction, of cast iron tubes, comprising a die block aligned along the vertical extraction axis and a liquid iron supply device feeding the die, machine in which at least one seal is disposed between the outlet of the device supply and entry of the sector.
- the present invention aims to overcome these various drawbacks by proposing a casting machine in which sealing against liquid metal is ensured both in the ramp-up phase and in the constant high temperature operating phase.
- the subject of the invention is a device for clamping a casting table of a vertical continuous casting machine, along an axis vertical extraction, of parts, in particular of tubes, in cast iron, the table casting comprising on the one hand a die block aligned along the vertical axis extraction, and secondly a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the liquid iron supply device and the die block, characterized in that it comprises constant force clamping means, in parallel to the vertical extraction axis, from the die block against the exit of the supply of liquid iron to tighten the seals.
- the invention also relates to a casting table of a vertical continuous casting machine, along a vertical axis (X-X) of extraction, of parts, in particular tubes, of cast iron, the casting table comprising on the one hand, a die block aligned along the vertical axis (X-X) of extraction, and secondly, a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the device for supplying liquid iron and the die block, characterized in that it includes a clamping device as defined above.
- Figure 1 a continuous casting table 1 vertical ascending of parts, in particular of T tubes, in cast iron.
- This table casting includes a device 3 for supplying liquid iron and a die block 5 powered by its lower end by this supply device 3.
- the tube T is extracted from the die block 5 by non-extracting means represented, upwards, along the vertical X-X extraction axis.
- the meaning of the extraction force is represented by an arrow F.
- the device 3 for supplying liquid iron is placed on a chassis 6 and secured against lateral and vertical displacement thereon by vertical tie rods 7 and horizontal crosspieces 8. It includes a siphon 9 in the shape of a U made of a single piece of molded refractory concrete.
- This siphon 9 includes a liquid iron supply channel 10 formed by a vertical downward portion 10A of entry of the molten iron, a horizontal part (not visible in the figures) and a vertical part 10B liquid iron outlet, directed upwards.
- a base heater 11 is interposed between the die block 5 and the outlet of the siphon 9. Sealing of molten metal is ensured by two seals annulars 12A and 12B, a first 12A disposed between the outlet of the siphon 9 and the underside of the heating base 11, and a second 12B disposed between the upper face of the heating base 11 and the lower face of the die block 5.
- the siphon 9 and the heating base 11 are surrounded a carcass 13 in the thickness of which are wound windings inductors 14. These inductor windings 14 are supplied with current electric by an external current generator not shown for maintain molten iron by induction heating.
- the die block 5 is fixedly mounted in a retractable support 15 tray-shaped.
- This die block includes a cooling block 17 connected to a coolant circuit by 17A inlet pipes and output 17B.
- Block 17 has an extension on its upper face of reduced diameter. It is received in a conjugate housing 15A of the support 15 with vertical axis Y-Y and is fixed to it by means of a crown of axial screws 15B ( Figure 2).
- the relative position of the support 15 relative to the chassis 6 is determined by two columns 18 directed downwards, fixed to the support 15 diametrically opposite with respect to the die block 5, as the shows figure 2.
- figure 3 shows that each baluster 18 is guided in an associated ball bushing 19 which is fixed to the chassis 6.
- the relative position of the support 15 relative to the chassis 6 and therefore the relative position of the die block 5 with respect to the chassis 6, are precisely defined in a plane perpendicular to the vertical axis X-X extraction, while the support-chassis distance can be adjusted parallel to the X-X axis.
- each cylinder 21 has a rod 22 of which the free end 23 is fixed by a pin 24 in a clevis 25 integral of the chassis 6.
- Each pin 24 is stopped in the yoke 25 by pins (not shown) so that the support 15 can easily be disassembled from the chassis 6.
- the body 21A of the jacks 21 is fixed by a flange 21B on the upper face of the plate 15 so as to be out of reach of the field induction generated by the inductor windings 14.
- each fluid cylinder 21 is connected by a pipe 26, 27 to a common pipe 29.
- This pipe common 29 is connected to a hydraulic unit 31 for regulating the clamping force of each cylinder, shown schematically.
- this hydraulic unit is also mounted on the chassis 6.
- the clamping force exerted on the seals 12A and 12B corresponds to the clamping force exerted by the jacks 21 to pull the yokes 25 in the direction of the support 15. Thanks to the fact that two cylinders connected to the hydraulic unit 31 by a common pipe 29, the applied clamping force is identical for each cylinder. In addition, once regulated, it is constant despite expansion phenomena which occur at the level of the heating base 11, and despite the phenomena of creep of the joints and adhesion of the tube T to the die, this thanks to the principle hydraulic operation.
- the clamping arrangement by hydraulic cylinders also acts as a "safety fuse". Indeed, when the extraction force of the tube T becomes greater than the force applied by the jacks, the elements of the die block tend to dissociate in the direction of extraction of the tube T. This results in loosening of the seals and a leakage of the liquid metal towards outside, and the machine stops without damage for the installation of tube production.
Description
La présente invention est relative à la coulée des métaux en fusion, et plus particulièrement à la coulée continue verticale de pièces métalliques, notamment de tubes, en fonte. Bien qu'elle s'applique à la coulée de différents types de pièces métalliques, elle est particulièrement avantageuse pour la coulée de tubes minces en fonte. L'expression "tubes minces" s'applique à un tube dont le rapport épaisseur/diamètre est faible, inférieur à 10 pour cent, plutôt qu'à l'épaisseur considérée isolément en soi.The present invention relates to the casting of metals into fusion, and more particularly to the vertical continuous casting of parts of metal, in particular of tubes, of cast iron. Although it applies to casting of different types of metal parts, it is particularly advantageous for casting thin cast iron tubes. The expression "thin tubes" applies to a tube with a low thickness / diameter ratio, less than 10 percent, rather than the thickness considered in isolation.
L'invention concerne plus précisément une machine de coulée
continue verticale, suivant le préambule de la revendication 1, qui est basé sur WO-A-94/26 444, suivant un axe vertical d'extraction, de tubes en fonte,
comprenant un bloc-filière aligné suivant l'axe vertical d'extraction et un
dispositif de fourniture de fonte liquide alimentant la filière, machine dans
laquelle au moins un joint d'étanchéité est disposé entre la sortie du dispositif
d'alimentation et l'entrée de la filière.The invention relates more precisely to a casting machine
vertical continuous, according to the preamble of
Pour assurer une bonne étanchéité au niveau du ou des joints, il est nécessaire d'appliquer une certaine force de serrage sur ceux-ci parallèlement à l'axe d'extraction des tubes. Cette force doit agir à l'encontre de la force d'extraction des tubes afin de comprimer les joints d'étanchéité et assurer ainsi l'étanchéité de l'ensemble.To ensure a good seal at the joint (s), it it is necessary to apply a certain clamping force on these parallel to the axis of extraction of the tubes. This force must act against of the extraction force of the tubes in order to compress the seals and thus ensuring the tightness of the assembly.
Lors de la montée en régime de la machine de coulée, les différents matériaux en contact avec le métal liquide se dilatent suivant des proportions différentes selon le matériau. Cette dilatation affecte le serrage des joints d'étanchéité, de telle sorte que les joints peuvent être endommagés et/ou l'étanchéité au métal liquide peut être perdue.When the casting machine rises, the different materials in contact with the liquid metal expand according to different proportions depending on the material. This expansion affects the tightening seals, so that the seals can be damaged and / or the liquid metal seal may be lost.
Des difficultés du même ordre peuvent résulter du fluage des joints au cours du temps, et également des phénomènes d'adhérence à la filière du tube en cours de fabrication.Similar difficulties may result from creep of joints over time, and also phenomena of adhesion to the tube industry during manufacture.
La présente invention vise à pallier ces divers inconvénients en proposant une machine de coulée dans laquelle l'étanchéité au métal liquide soit assurée aussi bien dans la phase de montée en régime que dans la phase de fonctionnement à température élevée constante.The present invention aims to overcome these various drawbacks by proposing a casting machine in which sealing against liquid metal is ensured both in the ramp-up phase and in the constant high temperature operating phase.
A cet effet, l'invention a pour objet un dispositif de bridage d'une table de coulée d'une machine de coulée continue verticale, suivant un axe vertical d'extraction, de pièces, en particulier de tubes, en fonte, la table de coulée comprenant d'une part un bloc-filière aligné suivant l'axe vertical d'extraction, et d'autre part un dispositif de fourniture de fonte liquide alimentant le bloc-filière, au moins un joint d'étanchéité étant disposé entre la sortie du dispositif de fourniture de fonte liquide et le bloc-filière, caractérisé en ce qu'il comprend des moyens de serrage à force constante, parallèlement à l'axe vertical d'extraction, du bloc-filière contre la sortie du dispositif de fourniture de fonte liquide pour serrer les joints d'étanchéité.To this end, the subject of the invention is a device for clamping a casting table of a vertical continuous casting machine, along an axis vertical extraction, of parts, in particular of tubes, in cast iron, the table casting comprising on the one hand a die block aligned along the vertical axis extraction, and secondly a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the liquid iron supply device and the die block, characterized in that it comprises constant force clamping means, in parallel to the vertical extraction axis, from the die block against the exit of the supply of liquid iron to tighten the seals.

- les canalisations de fluide des vérins sont réunies en une canalisation commune de fluide, et cette canalisation commune est reliée à l'unité de régulation de la force de serrage,
- les vérins à fluide sont des vérins hydrauliques,
- les vérins à fluide sont des vérins pneumatiques,
- les corps des vérins sont entièrement disposés en-dehors de l'espace compris entre les deux plans horizontaux qui limitent les enroulements inducteurs.
- the clamping means comprise a support for the die block displaceable along an axis substantially parallel to the vertical extraction axis, a frame on which the liquid iron supply device is placed, and at least two fluid cylinders, regularly distributed around the die block, each cylinder being connected to both said support and said chassis, and each cylinder being connected via a fluid line to a unit for regulating the clamping force of each cylinder,
- the fluid lines of the cylinders are combined in a common fluid line, and this common line is connected to the clamping force regulation unit,
- the fluid cylinders are hydraulic cylinders,
- the fluid cylinders are pneumatic cylinders,
- the cylinders bodies are entirely disposed outside the space between the two horizontal planes which limit the inductor windings.
L'invention a également pour objet une table de coulée d'une machine de coulée continue verticale, suivant un axe vertical (X-X) d'extraction, de pièces, en particulier de tubes, en fonte, la table de coulée comprenant d'une part un bloc-filière aligné suivant l'axe vertical (X-X) d'extraction, et d'autre part un dispositif de fourniture de fonte liquide alimentant le bloc-filière, au moins un joint d'étanchéité étant disposé entre la sortie du dispositif de fourniture de fonte liquide et le bloc-filière, caractérisé en ce qu'elle comprend un dispositif de bridage tel que défini ci-dessus.The invention also relates to a casting table of a vertical continuous casting machine, along a vertical axis (X-X) of extraction, of parts, in particular tubes, of cast iron, the casting table comprising on the one hand, a die block aligned along the vertical axis (X-X) of extraction, and secondly, a device for supplying liquid iron supplying the die block, at least one seal being disposed between the outlet of the device for supplying liquid iron and the die block, characterized in that it includes a clamping device as defined above.
D'autres caractéristiques et avantages de l'invention ressortiront
de la description suivante donnée à titre d'exemple sans caractère limitatif, en
regard des dessins annexés sur lesquels :
Sur la figure 1 est représentée une table 1 de coulée continue
verticale ascendante de pièces, en particulier de tubes T, en fonte. Cette table
de coulée comprend un dispositif 3 de fourniture de fonte liquide et un bloc-filière
5 alimenté, par son extrémité inférieure, par ce dispositif de fourniture
3. Le tube T est extrait du bloc-filière 5 par des moyens d'extraction non
représentés, vers le haut, suivant l'axe vertical X-X d'extraction. Le sens de
la force d'extraction est représenté par une flèche F. In Figure 1 is shown a continuous casting table 1
vertical ascending of parts, in particular of T tubes, in cast iron. This table
casting includes a
Le dispositif 3 de fourniture de fonte liquide est posé sur un
châssis 6 et assuré contre un déplacement latéral et vertical sur celui-ci par
des tirants verticaux 7 et des traverses horizontales 8. Il comporte un siphon
9 en forme de U réalisé d'une seule pièce en béton réfractaire moulé.The
Ce siphon 9 comprend un canal 10 d'alimentation en fonte liquide
formé par une partie verticale descendante 10A d'entrée de la fonte en fusion,
une partie horizontale (non visible sur les figures) et une partie verticale 10B
de sortie de la fonte liquide, dirigée vers le haut.This
En se référant en particulier à la figure 3, on voit qu'une base
chauffante 11 est interposée entre le bloc-filière 5 et la sortie du siphon 9.
L'étanchéité au métal en fusion est assurée par deux joints d'étanchéité
annulaires 12A et 12B, un premier 12A disposé entre la sortie du siphon 9 et
la face inférieure de la base chauffante 11, et un deuxième 12B disposé entre
la face supérieure de la base chauffante 11 et la face inférieure du bloc-filière
5.With particular reference to FIG. 3, it can be seen that a
Par ailleurs, le siphon 9 et la base chauffante 11 sont entourés
d'une carcasse 13 dans l'épaisseur de laquelle sont noyés des enroulements
inducteurs 14. Ces enroulements inducteurs 14 sont alimentés en courant
électrique par un générateur de courant extérieur non représenté pour
maintenir la fonte en fusion par un chauffage par induction.Furthermore, the
Le bloc-filière 5 est monté fixe dans un support 15 escamotable
en forme de plateau. Ce bloc-filière comporte un bloc de refroidissement 17
relié à un circuit d'un fluide de refroidissement par des tuyaux 17A d'arrivée
et 17B de sortie. Le bloc 17 présente sur sa face supérieure un prolongement
de diamètre réduit. Il est reçu dans un logement conjugué 15A du support 15
d'axe vertical Y-Y et y est fixé au moyen d'une couronne de vis axiales 15B
(Figure 2).The die
La position relative du support 15 par rapport au châssis 6 est
déterminée par deux colonnettes 18 dirigées vers le bas, fixées au support
15 de façon diamétralement opposée par rapport au bloc-filière 5, comme le
montre la figure 2. La figure 3 montre que chaque colonnette 18 est guidée
dans une douille à billes 19 associée qui est fixée sur le châssis 6.The relative position of the
Du fait de l'utilisation de colonnettes 18 coopérant avec des
douilles à billes 19, la position relative du support 15 par rapport au châssis
6 et de ce fait, la position relative du bloc-filière 5 par rapport au châssis 6,
sont précisément définies dans un plan perpendiculaire à l'axe vertical
d'extraction X-X, tandis que la distance support-châssis peut être ajustée
parallèlement à l'axe X-X.Due to the use of
Pour bloquer la position du support 15 suivant l'axe X-X par
rapport au châssis 6, deux vérins à fluide 21, tels que par exemple des vérins
hydrauliques ou des vérins pneumatiques, sont fixés en des positions
diamétralement opposées sur le support 15 (figure 2). Ainsi que cela est
représenté sur la figure 3, chaque vérin 21 comporte une tige 22 dont
l'extrémité libre 23 est fixée par un tourillon 24 dans une chape 25 solidaire
du châssis 6. Chaque tourillon 24 est arrêté dans la chape 25 par des
goupilles (non représentées) afin que le support 15 puisse facilement être
démonté du châssis 6. Le corps 21A des vérins 21 est fixé par une collerette
21B sur la face supérieure du plateau 15 afin d'être hors portée du champ
d'induction généré par les enroulements inducteurs 14.To block the position of the
Comme on le voit sur la figure 1, chaque vérin à fluide 21 est relié
par une canalisation 26, 27 à une canalisation commune 29. Cette canalisation
commune 29 est reliée à une unité hydraulique 31 de régulation de la
force de serrage de chaque vérin, représentée schématiquement. Avantageusement,
cette unité hydraulique est également montée sur le châssis 6.As seen in Figure 1, each
Une fois que la position du support 15 par rapport au châssis 6 est
bloquée par les vérins 21, le support et le châssis, ainsi que le bloc-filière 5
et que le dispositif de fourniture 3, forment un ensemble monobloc rigide. Cet
ensemble monobloc rigide repose sur un socle 40 fixe.Once the position of the
Pour serrer les joints d'étanchéité 12A et 12B, on règle une
certaine force de serrage des vérins par l'intermédiaire de l'unité de régulation
31. La force de serrage exercée sur les joints d'étanchéité 12A et 12B
correspond à la force de serrage qu'exercent les vérins 21 pour tirer les
chapes 25 en direction du support 15. Grâce au fait que l'on utilise deux
vérins reliés à l'unité hydraulique 31 par une canalisation 29 commune, la
force de serrage appliquée est identique pour chaque vérin. De plus, une fois
réglée, elle est constante malgré des phénomènes de dilatation qui se
produisent au niveau de la base chauffante 11, et malgré les phénomènes de
fluage des joints et d'adhérence du tube T à la filière, ceci grâce au principe
hydraulique de fonctionnement.To tighten the
Par ailleurs, l'agencement de serrage par des vérins hydrauliques joue aussi un rôle de "fusible de sécurité". En effet, lorsque la force d'extraction du tube T devient supérieure à la force appliquée par les vérins, les éléments du bloc-filière tendent à se dissocier dans le sens d'extraction du tube T. Il en résulte un desserrage des joints et une fuite du métal liquide vers l'extérieur, et la machine s'arrête sans dommages pour l'installation de production de tubes.Furthermore, the clamping arrangement by hydraulic cylinders also acts as a "safety fuse". Indeed, when the extraction force of the tube T becomes greater than the force applied by the jacks, the elements of the die block tend to dissociate in the direction of extraction of the tube T. This results in loosening of the seals and a leakage of the liquid metal towards outside, and the machine stops without damage for the installation of tube production.
