Abstract

Le dispositif comporte une tete de mesure en matière céramique emboitée dans un tube de support et comprenant à l'avant comme capteurs de mesures, une cellule électro-chimique (5), une électrode de contact (6) et un thermo-élément (7) couverts d'un chapeau. Pour la détermination de la teneur en oxygène d'acier en fusion, en particulier au cours de la fabrication en convertisseur, les capteurs de mesure se trouvent dans une chambre de mesure (K), constituée d'un élément annulaire (3'), s'avançant axialement, de la tete de mesure (3). Des canaux de désaération (8) débouchant dans cette chambre, traversent la tete de mesure.The device comprises a ceramic measuring head fitted into a support tube and comprising at the front as measurement sensors, an electro-chemical cell (5), a contact electrode (6) and a thermo-element (7 ) covered with a hat. For the determination of the oxygen content of molten steel, in particular during manufacture in a converter, the measurement sensors are located in a measurement chamber (K), consisting of an annular element (3 '), advancing axially from the measuring head (3). Deaeration channels (8) opening into this chamber, pass through the measuring head.
