Description
'Mémoire descriptif déposé à l'appui d'une demande de brevet
de perfectionnement au brevet belge N* 888.255 déposé le
2.4.1981 au nom du C.R.M., pour des *Perfectionnements au procédé de coulée continue des métaux et dispositif pour
la mise en oeuvre de ce procédé".
<EMI ID=1.1>
Dans ce brevet principal, on a décrit une busette de coulée continue caractérisée en ce que aa partie
<EMI ID=2.1> <EMI ID=3.1>
relatif par rapport à sa partie supérieure ou par rapport au par.ier répartiteur, lequel mouvement est avantageusement rotatif circulaire, autour de l'axe �e la partie non tournante de la busette.
Le présent perfectionnement a pour but, dans le
<EMI ID=4.1>
dans laquelle la partie inférieure de la busette est plongée-
Selon une première variante de réalisation de la
<EMI ID=5.1>
mité d'au moins une ailette, de préférence sensiblement verticale et dont la rotation avec la busette entraîne la mise en mouvement du métal. Les dites ailettes peuvent être remplacées par des protubérances ayant le même effet d'entraînement tout en résistant davantage A l'abrasion et aux effets de flexion dus 1'action du métal liquide.
Selon une deuxième variante avantageuse, l'extrémité intérieure de la busette comporte un conduit terminé côté sortie par un évasement et dont la section transversale présente une forme non circulaire, ce qui permet également d'entrainer en mouvement l'acier dans lequel la busette est plongée.
REVENDICATIONS
1. Busette de coulée conforme à celles définies dans lea revendications du brevet principal, caractérisée en ce qu'elle eat munie, sur la face extérieure de son extremité, d'au moins une ailette, de préférence sensiblement verticale ou d'au moins une protubérance.
<EMI ID=6.1>
'' Descriptive memorandum filed in support of a patent application
to improve Belgian patent N * 888,255 filed on
2.4.1981 on behalf of the C.R.M., for * Improvements to the continuous metal casting process and device for
the implementation of this process ".
<EMI ID = 1.1>
In this main patent, a continuous casting nozzle has been described, characterized in that aa part
<EMI ID = 2.1> <EMI ID = 3.1>
relative with respect to its upper part or with respect to the distributor par.ier, which movement is advantageously circular rotary, around the axis e the non-rotating part of the nozzle.
The purpose of this improvement is, in the
<EMI ID = 4.1>
in which the lower part of the nozzle is immersed-
According to a first alternative embodiment of the
<EMI ID = 5.1>
mite of at least one fin, preferably substantially vertical and whose rotation with the nozzle causes the metal to move. Said fins can be replaced by protrusions having the same driving effect while being more resistant to abrasion and to the bending effects due to the action of liquid metal.
According to a second advantageous variant, the inner end of the nozzle comprises a conduit terminated on the outlet side with a flaring and whose cross section has a non-circular shape, which also allows the steel in which the nozzle is to be moved in movement. diving.
CLAIMS
1. pouring nozzle according to those defined in the claims of the main patent, characterized in that it is provided, on the external face of its end, with at least one fin, preferably substantially vertical or at least one protuberance.
<EMI ID = 6.1>
