PRECIS DE LA DIVULGATION:
Dispositif de rétention d'hydrocarbures dans un fond
de convertisseur d'aciérie utilisant des tuyères protégées par
un écoulement d'hydrocarbures. Ce dispositif est constitué
par une cuvette de rétention entièrement préfabriquée, comportant
d'une part un disque mince de mêmes dimensions que la plaque de
fond du convertisseur et posé sur celle-ci, formant ainsi le fond
de la cuvette, et d'autre part une bande cintrée suivant un
cylindre de même dimension que la plaque de fond et que le disque
précité, cette bande circulaire se trouvant sertie à froid sur
le disque; l'ensemble de cette cuvette se trouve posée sur
la plaque de fond. Le dispositif selon l'invention pallie aux
inconvénients associés au cheminement des hydrocarbures dans la
masse du fond du convertisseur.
