In order to reduce the length of the arm and permit transfer of the cages (stands) from the arm to an operational travelling crane and vice versa, outside the zone covered by the casting floor, the axis of rotation 24 of the said arm 20 is located at a distance from the ingot mould which is markedly shorter than the radius of curvature of the passage 15 formed by the rollers (rolls) of the cages (stands) 14, the fixed guides 22, 220 each include a lower part 22a, 220a perpendicular to the direction of the said passage 15 and an upper part 22b, 220b directed towards the said axis of rotation 24 and the pair of fixed guides 220 which is furthest from the ingot mould 12 is located in the zone serviced by the travelling crane 34.

Description

La brésente invention concerne les installations oe coulée continue comnortant une lingotière. une serle de caues à rouleaux disbosees côte-à-côte dour former deux ransees
Parallèles de rouleaux délimitant entre elles un passage pour le produit coule comprenant une portion courbe suivie d une oortion rectiligne, et un dispositif pour enlever et mettre en place les cages de rouleaux.
The present invention relates to continuous casting installations including an ingot mold. a serle of caues with rollers arranged side by side to form two ransees
Parallels of rollers delimiting between them a passage for the flowing product comprising a curved portion followed by a rectilinear oortion, and a device for removing and placing the roll cages.

Plus particulièrement, l'invention a pour objet un dispositif pour enlever et mettre en place le cage' de rouleaux dans une installation de coulée continue oui comprend des guides fixes disposés par paires ae part et d autre des caoes et dans lesquels sont engages des qeiets montes sur le flanc des cages un bras monte au-dessus des cages de façon à pouvoir plvoter autour d'un axe fige. More particularly, the subject of the invention is a device for removing and placing the roll cage in a continuous casting installation yes, includes fixed guides arranged in pairs on either side of the caoes and in which the qeiets are engaged mount on the side of the cages an arm rises above the cages so as to be able to float around a fixed axis.

horizontal et parallèle aux axes des pouleaux, et être plate bout - à-bout avec les guides de chaque cage et approximetlvement dans le prolongement de ceux-ci. des mo ens pour commander la rotation dudit bras et des movens de levage pour déolacer les segments le long des guides fixes et du bras.horizontal and parallel to the axes of the hens, and be flat end-to-end with the guides of each cage and approximately in the extension of these. means to control the rotation of said arm and lifting movens to deolace the segments along the fixed guides and the arm.

Dans les installations du type concerne, l axe de rotation du bras est géneralement confondu avec l'axe passant par le centre de courbure de la portion courbe du passage défini par les rouleaux ou situé au voisinage de celui-ci et une ouverture prévue dans le plancher de coulee permet de reprendre une cage chargée sur le bras et inversement de charger sur le bras une cage de remplacement, au moyen d un oont-roulant. Dans ces installations le bras a une orande longueur et, par conséquent, est lourd et nécessite des movens pulssants oour le faire tourner.Par ail 1 surs, le transfert des cages a travers une ouverture du plancher de coulée peut mener le travail du personnel de service notamment dans les installations à plusieurs files. In installations of the type concerned, the axis of rotation of the arm is generally coincident with the axis passing through the center of curvature of the curved portion of the passage defined by the rollers or located in the vicinity thereof and an opening provided in the pouring floor allows to take up a cage loaded on the arm and conversely to load on the arm a replacement cage, by means of a rolling oont. In these installations the arm has a long length and, therefore, is heavy and requires pulverizing movens to rotate it. By the way, the transfer of the cages through an opening of the casting floor can carry out the work of the personnel of service especially in multi-line installations.

Pour remédier a ces inconvénients, on a propose de monter le bras divotant sur un chariot déplaÇable sur des rails horizontaux disposés parallèlement a la direction d'évacuation du produit coulé ou perpendiculairement å celleci et permettant d'amener les cages das une zone o elles souvent etre reprises par un pont-roulant. Cette solution est coteuse et complique les opérations d'enlevement et de mise en olace des cages car elle nécessite un Positionnement précis du chariot. To overcome these drawbacks, it has been proposed to mount the divider arm on a movable trolley on horizontal rails arranged parallel to the direction of discharge of the cast product or perpendicular to it and making it possible to bring the cages to an area where they often be taken up by an overhead crane. This solution is expensive and complicates the operations of removing and setting up the cages because it requires precise positioning of the carriage.

Le but de la presente invention est de réduire la longueur du bras et de permettre le transfert des cages du bras au pont-roulant et vice-versa en dehors de la zone couverte par le plancher de coulée, sans compliquer la construction ni l'utilisation du dispositif. The object of the present invention is to reduce the length of the arm and to allow the transfer of the cages from the arm to the overhead crane and vice versa outside the area covered by the casting floor, without complicating construction or use. of the device.

L'installation objet de la présente invention est caractérisée en ce que l'axe de rotation du bras est situé a une distance de la lingotière inférieure au rayon de courbure du passage formé par les deux rangées de rouleaux, en ce que les guides fies coopérant avec le bras comportent, chacun, une oartie inférieure perpendiculaire à la direction dudit passaqe et une partie superieure dirigée vers l'axe de rotation du bras et en ce oue la paire de guides flxes la plus éloignee de la lingotière est située dans une zone desservie par un pont-roulant dont le crochet peut entre amena à 1 aplomb d'une partie sensiblement verticale desdits gui des. The installation which is the subject of the present invention is characterized in that the axis of rotation of the arm is located at a distance from the mold less than the radius of curvature of the passage formed by the two rows of rollers, in that the cooperating guides with the arm each have a lower part perpendicular to the direction of said passage and an upper part directed towards the axis of rotation of the arm and in this case the pair of the most distant fixed guides from the ingot mold is located in a service area by an overhead crane, the hook of which can lead to a plumb line of a substantially vertical part of said mistletoe.

Pour enlever une cage au moven du dispositif de l'invention on amène le bras dans le prolongement des gui des associés à cette cage. on charge 1a cage sur le bras. on amène ensuite le bras dans le drolongement de la danre oe gui des la blus éloignée de la lingotiere, on oescend la cage dans ces quides lusqu à ce ou elle se trouve dans leur dartie sensiblement verticaie et repose sur des tasseaux amovlbles dréalablement mis en blace, et, abres avoir détaché la cepe du svsteme de levage du bras et éloigné celui-ci, on vient reprendre la cage au moyen du pont--roulant. Pour mettre en place une nouvel le cage on effectue les opérations inverses. To remove a moven cage from the device of the invention, the arm is brought in line with the mistletoe associated with this cage. the cage is loaded on the arm. we then bring the arm in the drolongation of the dan oe mistletoe of the blus far from the ingot mold, we descend the cage in these quides lusqu to what it is in their dartie substantially verticaie and rests on removable cleats dreably put in blace , and, after having detached the cap from the lifting system of the arm and removed the latter, the cage is taken up again by means of the overhead crane. To set up a new cage, the reverse operations are carried out.

La cage montee dans la dernière paire de guides, ainsi que les cages Si tuées en aval sont enlevées et mises en blece uniquement au moven du pont-roulant.The cage mounted in the last pair of guides, as well as the cages If killed downstream, are removed and put in blece only at the moven of the overhead crane.

D'autres carctéristiques de l'invention apparaîtront a la lecture de la description qui suit et se réfère au dessin l'accomPagnant qui est une vue, partiellement en coupe et partiellement en élévation, d'une machine de coulée continue équipée d'un dispositif d'enlèvement et de mise en place des cages de rouleaux conforme à l'invention. Other characteristics of the invention will appear on reading the description which follows and refers to the accompanying drawing which is a view, partly in section and partly in elevation, of a continuous casting machine equipped with a device for removing and placing roll cages according to the invention.

La machine de coulée continue représentée sur le desin comporte un chyâssis 10 portant une lingotière 12, à sa partie supérieure, et une série de cages de rouleaux 14 disbosese a la suite les unes des autres pour former deux rangées parallèles de rouleaux délimitant entre elles un bassage pour le Drodult coulé comprenant une portion courbe, dont le centre de courbure n est situé au niveau de la lingotiere, suivie d une portion rectiligne et horizontale. Un plancher 16 soutenu par une charpente 18 est prévu au niveau de la 1 ingotiere.  The continuous casting machine shown in the drawing comprises a chassis 10 carrying an ingot mold 12 at its upper part, and a series of roll cages 14 disbosese one after the other to form two parallel rows of rollers delimiting between them a basing for the poured Drodult comprising a curved portion, the center of curvature of which is located at the level of the ingot mold, followed by a rectilinear and horizontal portion. A floor 16 supported by a frame 18 is provided at the level of the 1 ingotiere.

Pour mettre en place et enlever les cages de rouleaux on utilise un dispositif constitué, d'une part, par un Uras pivotant 20 et, d'autre part, par des guides fixes disposes par paire de part et d autre des cages et dans lesquels sont engagés des galets montes sur le flanc des cages. To install and remove the roller cages, a device is used which is made up, on the one hand, by a pivoting Uras 20 and, on the other hand, by fixed guides arranged in pairs on either side of the cages and in which pebbles mounted on the side of the cages are engaged.

Le bras 20 est monté pivotant sur un axe 24 dispose horizontalement et parallèlement aux axes des rouleau des cages et porté par des paliers fixés sur la charpente 18. The arm 20 is pivotally mounted on an axis 24 arranged horizontally and parallel to the axes of the rolls of the cages and carried by bearings fixed to the frame 18.

L axe 4 est situé approximativement à mi-distance entre la lingotière et le centre de courbure 0. Le bras 20 comporte de éléments de guidage 26 espacés l'un de l'autre de facon à pouvoir etre amenés dans le prolongement des guides de chaque paire de guides fixes 22 et aptes à recevoir les galets des cages pour permettre leur déplacement le long du bras. I1 porte un groupe moto-réducteur 28 muni d'un pignon engrenant avec une crémaillère circulaire 30 fixée sur la charpente et permettant de faire tourner le bras autour de son ae, et un treuil 32 dont le câble peut être accroche aux cages 14 bour les débiacer le lone des guides 22 et ou erax 20,
lous les quides 22, à l exception de ceus de la caoe supérieure 14a. comportent une Dartie inféra autre perpendiculaire à la direction du passage 15 délimité par ie deur rangees de rouleaux et une partie supérleure 22b dires vers l axe de rotation 24 du bras 20. Les guides 220 de la cage 14b, oui est la cage munie de guides la blus élolones de la lingotière, comportent en outre une parte intermédiere, verticale 220c. Dans certains cas. les par 220a et 220c dourront être allgnées et ne sêront alors das distinctes.
The axis 4 is located approximately halfway between the mold and the center of curvature 0. The arm 20 has guide elements 26 spaced from one another so as to be able to be brought in the extension of the guides of each pair of fixed guides 22 and able to receive the rollers of the cages to allow their movement along the arm. I1 carries a geared motor group 28 provided with a pinion meshing with a circular rack 30 fixed on the frame and making it possible to rotate the arm around its ae, and a winch 32 whose cable can be hooked to the cages 14 bour les clear the lone of the guides 22 and or erax 20,
all quides 22, except for those of the upper caoe 14a. have an inferior Dartie other perpendicular to the direction of the passage 15 delimited by their rows of rollers and an upper part 22b towards the axis of rotation 24 of the arm 20. The guides 220 of the cage 14b, yes is the cage provided with guides the blus elolones of the ingot mold, further comprise an intermediate part, vertical 220c. In some cases. pars 220a and 220c must be allocated and will not then be separate.

La cage 14b se trouve oratiouemebnt à l'extrémité de la portion courbe du bassag e15, à l'aplomb du centre de courbure 0. Cette cage, ainsi aue les cages suivantes trouvent dans une zone desservie par un pont-roulant "4. eiclur enlever la cage 14b. il suffit de l'accrocher au croche du pont-roulant et de la soulever pour la dégager des gui des :on peut alors la transporteur à l'emelacement voulu au moyen du pont-roulant. Pour mettre en place une nouvelle cage on effectue les opérations inverses. L'extrémité supérieure de la partie verticale 220c des guides est ouverte pour permettre ces manoeuvres. The cage 14b is oratiouemebnt at the end of the curved portion of the bassag e15, plumb with the center of curvature 0. This cage, thus aue the following cages found in an area served by an overhead traveling crane "4. eiclur remove the cage 14b, just hang it on the crane crane and lift it to free it from the mistletoe: you can then transport it to the desired location by means of the crane bridge. new cage the reverse operations are carried out The upper end of the vertical part 220c of the guides is open to allow these maneuvers.

Pour enlever l'une quelconque des autres cages, on amène le bras 20 en alignement avec les gui des 22 de la cage choisie. on accroche le csble du treuil 32 à la cage et on la hisse sur le bras au moyen du treuil. On amène ensulte le bras en alignement avec les guides 220. on descend la caoe l le long de ces qui des jusou'à ce ou'elle se trouve dans la partie verticale 220c de ceul-ci et repose sur des taseau 36 finés de manière amovible sur les guides. On décrocre alors le cabale du treuil 32 d la cage et celle-ci est enlevée au moyen du pont-roulant 34, On effectue les opérations inverses pour mettre en place une nouvelle cage. To remove any of the other cages, the arm 20 is brought into alignment with the mistletoes 22 of the selected cage. hook the cable of the winch 32 to the cage and hoist it on the arm by means of the winch. The arm is brought into alignment with the guides 220. the caoe is lowered along these which, until it is in the vertical part 220c of the latter and rests on posts 36 so finished removable on the guides. The winch cabal 32 is then unhooked from the cage and the latter is removed by means of the overhead crane 34. The reverse operations are carried out to set up a new cage.
