Description
Procédé de fabrication de lingots crénelés La présente invention a pour objet un procédé de fabrication de lingots crénelés.
Il est connu de munir de crénelages les lingots obtenus par coulée d'un métal en fusion dans des lingotières ou moules en fonte. A cet effet le fond des moules présente des dentelures de hauteur et épaisseur plus ou moins importantes. On obtient ainsi des lingots tels que représentés aux fig. 1 et 2, en vue de face et en coupe.
Il est également connu de réaliser un crénelage dans des lingots coulés dans des lingotières à fond plat. Dans ce cas, on plonge, après coulée, une grille ou herse, dont les dentelures pénètrent profondément dans la partie supérieure du bain métallique en fusion. On obtient alors des lingots tels que repré sentés aux fig. 3 et 4.
Ces procédés de fabrication de lingots présentent des inconvénients majeurs. C'est ainsi que leur cou lée, tout d'abord, s'avère longue et difficile ; d'autre part, leurs manipulation et stockage sont rendus déli cats par suite de leur longueur limitée, qui, en géné ral, est inférieure à une .quarantaine de centimètres et de l'ordre de 370 mm.
Le procédé selon l'invention permet la fabrica tion rapide et économique de lingots crénelés, suppri mant en partie ou en totalité les divers inconvénients inhérents auxdits procédés connus.
A cet effet ce procédé est caractérisé en ce qu'on coule du métal en continu pour former une ébauche allongée, en ce qu'on estampe cette ébauche pendant qu'elle est à l'état encore malléable de manière syn chrone avec la coulée, à l'aide d'une presse ayant une matrice présentant des dentures régulièrement espa cées et en ce qu'on découpe ensuite cette ébauche en tronçons. Les fig. 5 et 6 du dessin annexé représentent, à titre d'exemples vus de face et en coupe, un lingot crénelé, obtenu selon le présent procédé, à partir d'une ébauche de section trapézoïdale.
La fig. 7 représente une installation pour la mise en aeuvre du procédé.
Dans une application dudit procédé à la métal lurgie des métaux légers, tels qu'aluminium et alliages d'aluminium entre autres, on opère ainsi qu'il est représenté schématiquement et à titre d'exemple à la fig. 7.
Le chiffre de référence 1 désigne un appareillage de coulée continue, produisant une ébauche de sec tion trapézoïdale 2, au moyen d'une roue tournante à gorge périphérique, sur laquelle vient s'appliquer une bande recouvrant ladite gorge. L'ébauche, après guidage au moyen d'un jeu de roues 3, est introduite sous une presse emboutisseuse mécanique 4 équipée d'une matrice 5 en forme de peigne ; cette matrice vient frapper l'ébauche, à chaque coup de presse, y gravant profondément l'image de ses dentelures. Un dispositif éjecteur fixe 6, en forme de grille, empêche l'arrachage de l'ébauche par la matrice, au cours de la remontée de celle-ci par la presse.
A la sortie de la presse est placée une cisaille automatique 7 sectionnant l'ébauche emboutie en éléments de lon gueur donnée ; les lingots cannelés, ainsi obtenus, sont recueillis en 8.
Les cadences de frappe, de la presse, et de sec tionnement, de la cisaille, sont synchronisées en fonc tion de la vitesse de la coulée continue du métal en fusion, soit de la vitesse de progression de l'ébauche.
On peut également au moyen du procédé sus- décrit fabriquer des lingots d'un produit métallique désoxydant couramment utilisé dans les aciéries. Ces lingots présentent alors le grand intérêt de pouvoir aisément se fragmenter en éléments de longueur et de poids variables et, le cas échéant, faibles.
Method for manufacturing crenellated ingots The present invention relates to a process for manufacturing crenellated ingots.
It is known practice to provide ingots obtained by casting a molten metal into ingots or cast iron molds with crenellations. For this purpose the bottom of the molds has notches of varying height and thickness. Ingots are thus obtained as shown in FIGS. 1 and 2, in front view and in section.
It is also known to perform aliasing in ingots cast in ingot molds with a flat bottom. In this case, after casting, a grid or harrow is immersed, the serrations of which penetrate deeply into the upper part of the molten metal bath. Ingots are then obtained as shown in FIGS. 3 and 4.
These ingot manufacturing processes have major drawbacks. This is how their neck, first of all, is long and difficult; on the other hand, their handling and storage are made delicate owing to their limited length, which, in general, is less than about forty centimeters and of the order of 370 mm.
The method according to the invention allows the rapid and economical manufacture of crenellated ingots, eliminating in part or in whole the various drawbacks inherent in said known methods.
To this end, this process is characterized in that metal is continuously cast to form an elongated blank, in that this blank is stamped while it is in the still malleable state synchronously with the casting, using a press having a die having regularly spaced teeth and in that this blank is then cut into sections. Figs. 5 and 6 of the appended drawing show, by way of examples seen from the front and in section, a crenellated ingot, obtained according to the present process, from a blank of trapezoidal section.
Fig. 7 represents an installation for the implementation of the process.
In an application of said process to the metal lurgy of light metals, such as aluminum and aluminum alloys among others, the procedure is as shown schematically and by way of example in FIG. 7.
The reference numeral 1 denotes a continuous casting apparatus, producing a blank of trapezoidal section 2, by means of a rotating wheel with a peripheral groove, on which is applied a strip covering said groove. The blank, after guidance by means of a set of wheels 3, is introduced under a mechanical stamping press 4 equipped with a die 5 in the form of a comb; this die strikes the blank with each press stroke, deeply engraving the image of its indentations on it. A fixed ejector device 6, in the form of a grid, prevents the blank from being torn off by the die during the latter's ascent by the press.
At the outlet of the press is placed an automatic shear 7 cutting the stamped blank into elements of given length; the fluted ingots thus obtained are collected in 8.
The rates of striking, of the press, and of sectioning, of the shears, are synchronized as a function of the speed of the continuous casting of the molten metal, that is to say of the speed of advance of the blank.
It is also possible, by means of the above-described process, to manufacture ingots of a deoxidizing metal product commonly used in steelworks. These ingots then have the great advantage of being able to easily fragment into elements of variable length and weight and, where appropriate, weak.
