Abstract

L'invention concerne un dispositif (1) pour l'écriquage de pièces (2) chaudes et froides telles que des brames en acier, dans et à la sortie des installations de coulée continue, au moyen de chalumeaux d'écriquage (5), comprenant une tour d'écriquage verticale (3), dans laquelle est agencé un cadre à chalumeaux d'écriquage (4) horizontal portant une pluralité de chalumeaux d'écriquage (5) agencés sur ses quatre côtés, déplacable verticalement à l'intérieur de la tour. Le cadre à chalumeaux d'écriquage (4) entoure une pièce (2) à écriquer posée verticalement sur une de ses faces frontales sur une structure de support (6) placée dans la cage d'écriquage (7) de la tour d'écriquage (3). Un mécanisme de déplacement (10) et des éléments de guidage formés dans la tour d'écriquage (3) permettent le déplacement vertical du cadre à chalumeaux d'écriquage horizontal (4) dans la cage d'écriquage (7). Une buse de grenaillage (12) installée à proximité des chalumeaux d'écriquage (5) est prévue pour l'élimination par grenaillage, dans une direction perpendiculaire à la verticale, de l'acier et du laitier fondus se formant sur la pièce. Cette installation permet l'écriquage simultané de toutes les faces d'une pièce (2) dans le sens vertical.
