Abstract

La présente invention concerne un procédé de coulée semi-continue d'une barre (1) en acier dans une machine de coulée continue et la machine de coulée continue elle-même. L'objectif de l'invention est de proposer un procédé de coulée semi-continue d'une barre (1) en acier, selon lequel la barre présente une faible ségrégation centrale et une faible porosité, mais peut toutefois être coulée rapidement. Cet objectif est atteint par les étapes de procédé suivantes : - démarrage de la coulée par la machine de coulée continue, de l'acier liquide étant coulé dans la lingotière à base ouverte (2) fermée par une fausse barre (6) et l'acier liquide formant avec la fausse barre une tête de barre (1a) entièrement solidifiée et ensuite une barre (1b) partiellement solidifiée; - retrait de la barre (1b) partiellement solidifiée de la lingotière à base ouverte (2); - appui et guidage de la barre (1b) partiellement solidifiée dans le guidage de barre (3), la barre (1b) partiellement solidifiée étant refroidie par le refroidissement secondaire (4); - fin de la coulée par la machine de coulée continue, la coulée d'acier liquide dans la lingotière à base ouverte (2) étant terminée et une queue de barre (1c) se formant; - retrait de la queue de barre (1c) hors de la lingotière à base ouverte (2); - arrêt du retrait, de sorte que la queue de barre (1c) se trouve hors de la lingotière à base ouverte (2); - arrêt du refroidissement secondaire (4); - refroidissement contrôlé ou régulé de la barre (1b) partiellement solidifiée jusqu'à la solidification totale de la barre (1) dans la zone de refroidissement tertiaire (5) de la machine de coulée continue, le refroidissement s'effectuant plus intensément à la tête de la barre (1a) et de manière décroissante jusqu'à la queue de la barre (1c); et - extraction de la barre (1) hors de la machine de coulée continue.
