Abstract
L'invention concerne un procédé pour contrôler la température de l'acier à la surface du bain d'une coquille de coulée continue (1) dans le domaine de la métallurgie secondaire (4) dans son ensemble, avec une étape de processus déterminante pour la température finale (4.1) tel qu'un four-poche, jusqu'à la percée de four (5) au cours d'un processus de production d'acier. Ce procédé est caractérisé en ce que la température de l'acier à la surface du bain est contrôlée sur la base de T¿ML? = T¿li? + X ·C (X = 5 - 15·C) et respectée en tenant compte de la détermination d'une saute de température (9) entre la surface du bain dans la coquille (1) et un distributeur (3) en relation avec la vitesse de coulée (6) pour un format de barre prédéterminé, de l'historique de la poche (7) en termes de périodes, comme p. ex. "poche pleine", "poche vide", et de l'état de la poche, comme p. ex. son revêtement, son vieillissement, ainsi que d'une saute de température de l'acier entre le distributeur (3) et la dernière température de four-poche (LF-ex).
