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.
