Abstract
LA PRESENTE INVENTION CONCERNE UN PROCEDE ET UN APPAREIL POUR MESURER LE NIVEAU DE LA ZONE DE FUSION DANS UN HAUT FOURNEAU. PLUSIEURS CABLES 2 SONT ENTRAINES AVEC LA CHARGE A PARTIR DU SOMMET D'UN HAUT FOURNEAU 3, ET LEURS EXTREMITES AVANT FONDENT LORSQU'ELLES PARVIENNENT DANS LA ZONE DE FUSION DE CE HAUT FOURNEAU 3. ON MESURE LA LONGUEUR DE CHAQUE CABLE 2 JUSQU'A SON EXTREMITEFONDUE, A PARTIR DES CARACTERISTIQUES DE L'ONDE FORMEE PAR REFLEXION D'UNE IMPULSION DE TENSION, A L'EXTREMITE FONDUE DES CABLES 2, ET ON DETERMINE LE NIVEAU M DE LA ZONE DE FUSION A L'INTERIEUR DU HAUT FOURNEAU 3 APRES AVOIR CORRIGE LA LONGUEUR DE CABLE 2 OBTENUE EN FONCTION DE L'EVENTUELLE DEFLEXION DE CE CABLE 2 DANS LE HAUT FOURNEAU 3. AVEC PLUSIEURS CABLES 2 EN DES EMPLACEMENTS RADIAUX DIFFERENTS, ON PEUT DEFINIR LA FORME DE LA LIMITE SUPERIEURE DE LA ZONE DE FUSION. APPLICATION A LA MESURE ELECTRIQUE DU NIVEAU DE LA ZONE DE FUSION DANS UN HAUT FOURNEAU.
