Abstract

a. L'invention concerne un procédé destiné à contrôler le niveau de métal en fusion dans le moule d'un appareil de coulée en continu. b. On met en marche les rouleaux extracteurs dès le démarrage d'une opération et règle leur vitesse en détectant l'écart entre le niveau de métal liquide dans le moule, et un niveau de réglage prévu. c. Ce procédé permet d'obtenir un fonctionnement plus sûr, évitant les débordements par le haut du moule et le coulage par sa partie inférieure.at. A method for monitoring the level of molten metal in the mold of a continuous casting apparatus is disclosed. b. The extractor rollers are started as soon as an operation is started and their speed is adjusted by detecting the difference between the level of liquid metal in the mold and a planned adjustment level. vs. This process makes it possible to obtain safer operation, preventing overflows from the top of the mold and pouring from its lower part.
