Abstract
L'invention a pour objet un procédé de régulation du niveau du ménisque (13) du métal liquide dans une lingotière (5) d'une machine de coulée continue des métaux, selon lequel on recueille les signaux électriques fournis par au moins une paire de capteurs (17, 18) surplombant ledit ménisque, lesdits signaux étant fonction des distances respectives (h1, h2) entre lesdits capteurs et ledit ménisque, on combine ces deux signaux de manière à obtenir un signal unique représentatif d'un niveau fictif dudit ménisque, et on envoie ledit signal à des moyens de commande (15, 24) d'un dispositif (14) de régulation du débit de métal pénétrant dans la lingotière, pour que lesdits moyens de commande actionnent ledit dispositif de manière à ramener ledit niveau fictif dudit ménisque à une valeur de consigne prédéterminée (h), caractérisé en ce qu'on conditionne chaque signal issu desdits capteurs, en éliminant les oscillations ayant à la fois une fréquence supérieure à un seuil (F) et une amplitude inférieure à un seuil (D). L'invention concerne aussi un mode de combinaison desdits signaux, et un dispositif pour mettre en oeuvre ledit procédé.
