_ Mémoire descriptif déposé à l'appui d'une demande de brevet ‘d'addition à la demande de brevet luxembourgeois N° 82.361, déposée le 14.4.1980 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"._ Descriptive brief filed in support of a patent application for addition to the Luxembourg patent application No. 82.361, filed on 14.4.1980 in the name of the CRM, for "Improvements to the continuous casting process for metals and device, for the implementation of this process ".

ÎLa présente invention se rapporte à des perfectionnements apportés à une busette de coulée continue, du genre de celle décrite dans la demande de brevet luxembourgeois citée ci-dessus et appelée demande de brevet principale.ÎLa present invention relates to improvements made to a continuous casting nozzle, of the kind described in the Luxembourg patent application cited above and called main patent application.

Dans cette demande de brevet principale, on a décrit une busette de coulée continue caractérisée en ce que sa / partie inférieure, constituée de la portion destinée à être f\ Ψ i 2.- î I « ί i i j , immergée et d'au moins le tronçon le plus inférieur de sa partie non immergée est munie de moyens pour la soumettre à un mouvement relatif par rapport à sa partie supérieure ou par rapport au panier répartiteur, lequel mouvement est avantageusement rotatif circulaire, autour de l'axe de la partie non tournante de la i | busette.In this main patent application, a continuous casting nozzle has been described, characterized in that its / lower part, consisting of the portion intended to be f \ Ψ i 2.- î I "ί iij, submerged and at least the lowest section of its non-submerged part is provided with means for subjecting it to a relative movement with respect to its upper part or with respect to the distribution basket, which movement is advantageously circular rotary, around the axis of the non-submerged part turn of the i | nozzle.

Le présent perfectionnement a pour but, dans le cadre de la demande de brevet principale, de révéler quelques configurations avantageuses de la dite busette de coulée permet-1 tant de mettre facilement en mouvement la zone supérieure du métal j dans laquelle la partie inférieure de la busette est plongée.The purpose of this improvement is, within the framework of the main patent application, to reveal some advantageous configurations of the said pouring nozzle, so that the upper zone of the metal j in which the lower part of the busette is diving.

Selon une première variante de réalisation de la I busette, celle-ci est munie en la face extérieure de son extré- i mité d'au moins une ailette, de préférence sensiblement verticale i 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 à l'abrasion et aux effets de flexion dus à l'action du métal liquide.According to a first alternative embodiment of the I nozzle, the latter is provided on the outer face of its end with at least one fin, preferably substantially vertical i and the rotation of which with the nozzle causes the movement metal. 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.

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'entraîner en mouvement l'acier dans lequel la busette est plongée. / (According to a second advantageous variant, the inner end of the nozzle comprises a conduit terminated on the outlet side with a flare and whose cross section has a non-circular shape, which also makes it possible to drive the steel in which the nozzle is in motion. diving. / (
