Abstract

a. Installation de mesure et de réglage du niveau d'acier liquide dans une lingotière de coulée continue; b. caractérisée en ce qu'elle met à profit les variations de la fréquence propre d'un circuit oscillant électrique dont la bobine B, constituée d'un ou de plusieurs tours d'un conducteur rigide est supportée par ou encastrée dans un ou des éléments en matière réfractaire et est disposée à l'intérieur de la lingotière L, concentriquement à celle-ci et dans un plan horizontale. c. L'invention s'applique à la mesure et au réglage du niveau d'acier liquide dans une lingotière de coulée.at. Installation for measuring and adjusting the level of liquid steel in a continuous casting mold; b. characterized in that it takes advantage of the variations of the natural frequency of an electric oscillating circuit whose coil B, consisting of one or more turns of a rigid conductor is supported by or embedded in one or more elements in refractory material and is arranged inside the mold L, concentrically thereto and in a horizontal plane. vs. The invention applies to the measurement and adjustment of the level of liquid steel in a casting mold.
