Abstract

L'invention concerne un procédé et un appareil de détermination du niveau d'un liquide dans un récipient Elle se rapporte à un appareil dans lequel une électrode 30 peut être élevée et abaissée dans une poche 1 de coulée afin qu'elle permette la détermination de la position de l'interface du métal fondu et du laitier. L'électrode peut être utilisée dans diverses applications, notamment dans une opération de dégazage sous vide. Application à la détermination du niveau de l'acier fondu dans des récipients métallurgiques.The invention relates to a method and an apparatus for determining the level of a liquid in a vessel. It relates to an apparatus in which an electrode 30 can be raised and lowered in a ladle 1 so that it enables the determination of the position of the interface of the molten metal and the slag. The electrode can be used in various applications, in particular in a vacuum degassing operation. Application to the determination of the level of molten steel in metallurgical vessels.
