Abstract

Sonde à immersion pour la détermination électrochimique rapide de l'activité d'éléments dissous dans des bains métalliques par des mesures de tension sans débit. Sonde constituée par un noyau support métallique comportant un système de référence 2 et par une couche de recouvrement 3 constituée par un électrolyte solide, la couche de référence 2 étant formée de particules de métal et de son oxyde uniformément réparties. Application : détermination de l'activité de l'oxygène dans les bains de fonte et d'acier.Immersion probe for the rapid electrochemical determination of the activity of elements dissolved in metal baths by voltage measurements without flow. Probe formed by a metal support core comprising a reference system 2 and by a covering layer 3 formed by a solid electrolyte, the reference layer 2 being formed of particles of metal and its oxide uniformly distributed. Application: determination of oxygen activity in cast iron and steel baths.
