The invention relates to a method and a device for guiding and orienting a strand (5) in a continuous casting facili-ty for large-sized round sections made of steel or a similar material. In order to prevent the formation of cracks while the strand is oriented, the outer surface (15) of the strand is heated from above and from below inside the orienting track. For this purpose, po-rous burners (10, 17) are arranged in the discharge section of the directing track, the hot gas emitted from said burners flowing en-tirely around the outer surface (15) of the strand.
L'invention concerne un procédé et un dispositif de guidage et de dressage d'une barre (5) dans une installation de coulée continue pour ronds de grande dimension en acier ou en un matériau analogue. Le but de l'invention est d'éviter la formation de fissures lors du dressage de la barre en chauffant les faces supérieure et inférieure de la croûte (15) de la barre à l'intérieur de la ligne de dressage. A cet effet, des brûleurs poreux (10, 17), dont les fumées chaudes circulent sur tout le pourtour de la croûte (15), sont placés dans la partie côté sortie de la ligne de dressage.
