Abstract

The surface of the cylinder (1) coming into contact with the cast metal has a roughness which varies continuously along any generatrix of the cylinder (1). The roughness is generally greater in the end zones (4, 5) of the cylinder (1) than in the central zone (6). The roughness may be obtained by burnishing or by machining with removal of flakes.

Description

L'invention est relative à un cylindre pour une machine de coulée continueThe invention relates to a cylinder for a continuous casting machine

sité est supérieure à la rugosité de la partie centrale de la table Par parties extrêmales, on entend des zones  sity is greater than the roughness of the central part of the table By extreme parts, we mean areas

circonférentielles de la surface situées près des extrémi-  circumferentials of the surface located near the extremi-

tés latérales du cylindre Par partie centrale de la table, on entend la zone circonférentielle de la surface comprise entre les deux parties extrêmales précédemment définies L'avantage de ces rugosités différentes est de favoriser l'entraînement de la bande mince pendant la coulée. Les rugosités des parties extrêmales et centrale sont bien distinctes et sont obtenues, par exemple, par galetage de la surface des cylindres Sur ces cylindres, la rugosité varie de façon discontinue le long d'une génératrice Il en résulte un inconvénient: au droit de la discontinuité, il se forme sur la bande une marque qui peut affaiblir localement la bande et conduire à sa rupture le long de cette marque Il apparaît alors, en rive, des rubans étroits qui se séparent de la bande, s'emmêlent et s'évacuent mal, ce qui peut conduire à  lateral tees of the cylinder By central part of the table, we mean the circumferential area of the surface between the two extremes previously defined. The advantage of these different roughnesses is to favor the entrainment of the thin strip during casting. The roughnesses of the extreme and central parts are very distinct and are obtained, for example, by burnishing the surface of the cylinders. On these cylinders, the roughness varies discontinuously along a generatrix. This results in a drawback: at the right of the discontinuity, a mark is formed on the strip which can locally weaken the strip and lead to its rupture along this mark It then appears, on the bank, narrow ribbons which separate from the strip, become tangled and evacuate wrong, which can lead to

l'arrêt de la coulée.stopping the casting.

Le but de la présente invention est de proposer des cylindres qui évitent l'inconvénient précité tout en  The object of the present invention is to provide cylinders which avoid the above-mentioned drawback while

assurant un bon entraînement de la bande pendant la coulée.  ensuring good tape entrainment during casting.

La figure 4 est une coupe au voisinage de la surface d'un cylindre dont la rugosité a été obtenue par usinage. Le cylindre représenté à la figure 1 correspond à l'invention Il a une table 1 généralement cylindrique qui est partiellement au contact du métal coulé lorsque la machine de coulée continue de bandes minces sur lequel il  Figure 4 is a section near the surface of a cylinder whose roughness was obtained by machining. The cylinder represented in FIG. 1 corresponds to the invention. It has a generally cylindrical table 1 which is partially in contact with the cast metal when the casting machine continues with thin strips on which it

Ce cylindre comporte deux extrémités latérales 2 et 3 La table 1 du cylindre a une certaine rugosité, mais cette rugosité n'est pas constante Dans les zones extrêmales 4 et 5 situées près des extrémités latérales 2  This cylinder has two lateral ends 2 and 3 The table 1 of the cylinder has a certain roughness, but this roughness is not constant In the extreme zones 4 and 5 located near the lateral ends 2

The peculiarity of this cylinder is that the roughness varies continuously and gradually when one moves along a generatrix of the cylinder. This is what is shown in Figure 2 Parts A and A 'of the curve

Cette rugosité est maximale près des extrémités latérales du cylindre puis décroît régulièrement jusqu'à la valeur de la partie B de la courbe correspondant à la zone  This roughness is maximum near the lateral ends of the cylinder then decreases regularly until the value of part B of the curve corresponding to the area

draient perturber l'évacuation de la bande.  should disturb the evacuation of the tape.

La rugosité peut être obtenue par différents procédés. Selon un premier procédé on effectue un galetage  The roughness can be obtained by different methods. According to a first method, a burnishing process is carried out

de la surface du cylindre.from the surface of the cylinder.

Pour obtenir une rugosité variant régulièrement, on fait varier progressivement la pression de galetage au fur et à mesure que l'outil de galetage se déplace le long de la table du cylindre Dans les zones extrêmales, cette pression est importante puis est réduite progressivement jusqu à une valeur plus faible correspondant à la rugosité  To obtain a regularly varying roughness, the burnishing pressure is gradually varied as the burnishing tool moves along the cylinder table. In the extreme areas, this pressure is high then is gradually reduced until a lower value corresponding to the roughness

de la zone centrale.of the central area.

L'homme de métier sait adapter la pression de galetage à la rugosité qu'il veut obtenir; il peut donc  A person skilled in the art knows how to adapt the burnishing pressure to the roughness that he wants to obtain; so he can

les rives seraient plus minces que la partie centrale.  the banks would be thinner than the central part.

Pour éviter cette non rectangularité de la section transversale de la bande, on peut usiner le cylindre 8 avant galetage comme cela est représenté à la figure 3 La zone centrale du cylindre 8 est cylindrique et d'un diamètre voisin du diamètre final souhaité pour le cylindre Les zones extrêmales 9 et 10 sont usinées de façon légèrement conique, de façon que les diamètres au voisinage des faces 11 et 12 soient plus faibles que le  To avoid this non-rectangularity of the cross section of the strip, the cylinder 8 can be machined before burnishing as shown in FIG. 3 The central zone of the cylinder 8 is cylindrical and of a diameter close to the final diameter desired for the cylinder The end zones 9 and 10 are machined in a slightly conical manner, so that the diameters in the vicinity of the faces 11 and 12 are smaller than the

diamètre de la table.diameter of the table.

Après un galetage plus important dans les zones extrêmales que dans la partie centrale, un tel cylindre  After a larger burnishing in the extreme areas than in the central part, such a cylinder

aura un diamètre à peu près constant sur toute sa largeur.  will have an almost constant diameter over its entire width.

L'homme de métier sait déterminer le gonflement engendré par le galetage Il sait donc déterminer la  A person skilled in the art knows how to determine the swelling caused by burnishing. He therefore knows how to determine the

par usinage avec enlèvement de copeaux.  by machining with chip removal.

Pour obtenir une rugosité sur la surface du cylindre 21 (figure 4) on crée sur celle-ci un sillon 20 hélicoïdal à spires jointives ayant pour axe, l'axe du cylindre 21 La surface du cylindre 21 présente une succession de creux 23 et de bosses 24 Les creux 23 correspondent au fond du sillon 20 et les bosses 24 à la  To obtain a roughness on the surface of the cylinder 21 (FIG. 4), a helical groove 20 with contiguous turns is created thereon having the axis of the cylinder 21 as its axis. The surface of the cylinder 21 has a succession of hollows 23 and bumps 24 The recesses 23 correspond to the bottom of the groove 20 and the bumps 24 to the

jonction entre deux spires successives.  junction between two successive turns.

Ce sillon 20 est obtenu par l'usinage par tour-  This groove 20 is obtained by turning machining

nage avec une avance importante de l'outil Si l'avance à chaque tour est a, le sillon 20 a une profondeur h; si l'avance est ai plus grande que a, la profondeur du sillon est h' plus grande que h. Ainsi, en faisant varier l'avance en cours d'usinage de la surface du cylindre 21, on peut faire varier la rugosité qui correspond à la profondeur du  swimming with a significant advance of the tool If the advance at each revolution is a, the groove 20 has a depth h; if the feed is ai greater than a, the depth of the groove is h 'greater than h. Thus, by varying the advance during machining of the surface of the cylinder 21, it is possible to vary the roughness which corresponds to the depth of the

sillon 20.groove 20.

De préférence, on choisira une avance importante dans les zones de la surface du cylindre qui se trouvent près des extrémités latérales de celui-ci et une avance  Preferably, a large advance will be chosen in the areas of the surface of the cylinder which are close to the lateral ends of the latter and an advance

plus faible dans la zone médiane.lower in the middle area.

A titre d'exemple non limitatif, on choisit une avance de 0,35 mm par tour sur les 15 premiers mm et les derniers mm de la table du cylindre à partir de ses extrémités latérales et une avance de 0,15 mm/tour sur la zone médiane de la table On obtient ainsi une rugosité Rz de 150 pm sur les zones o l'avance est de 0,35 mm/tour et une rugosité de 80 pm sur la zone o l'avance est de 0,15 mm/tour. On fait varier progressivement l'avance pour obtenir une rugosité qui varie continuement le long d'une génératrice de la surface du cylindre.  By way of nonlimiting example, we choose an advance of 0.35 mm per revolution on the first 15 mm and the last mm of the cylinder table from its lateral ends and an advance of 0.15 mm / revolution on the middle zone of the table We thus obtain a roughness Rz of 150 pm on the zones where the advance is 0.35 mm / revolution and a roughness of 80 pm on the zone where the advance is 0.15 mm / tower. The advance is varied gradually to obtain a roughness which varies continuously along a generatrix of the surface of the cylinder.
