Abstract

A.L'INVENTION CONCERNE UNE LANCE POUR L'ADDITION A DES BAINS METALLIQUES DE MATIERES SOLIDES AISEMENT VAPORISABLES ET REAGISSANT VIOLEMMENT. B.LA CHAMBRE DE VAPORISATION 4, 5 A UNE FORME CONICO-CYLINDRIQUE, LA PARTIE CONIQUE 4 SE TROUVANT AU-DESSUS DE LA PARTIE CYLINDRIQUE 5 QUAND LA LANCE EST EN POSITION D'EMPLOI; LA SURFACE LATERALE DE LA PARTIE CYLINDRIQUE 5 COMPORTE ALTERNATIVEMENT DES EVIDEMENTS 7 ET DES PERFORATIONS 6. C.CE DISPOSITIF PERMET NOTAMMENT DE DESULFURER LA FONTE AU MOYEN DE PARTICULES SOLIDES DE MG EN EVITANT LES VIBRATIONS DE LA LANCE.A. THE INVENTION RELATES TO A LANCE FOR ADDITION TO METAL BATHS OF EASILY VAPORISABLE AND VIOLENTLY REACTING SOLID MATERIALS. B. THE VAPORIZATION CHAMBER 4, 5 HAS A CONICO-CYLINDRICAL SHAPE, THE CONICAL PART 4 IS ABOVE THE CYLINDRICAL PART 5 WHEN THE LANCE IS IN THE OPERATION POSITION; THE LATERAL SURFACE OF THE CYLINDRICAL PART 5 ALTERNATIVELY INCLUDES RECESSES 7 AND PERFORATIONS 6. C. THIS DEVICE MAKES IN PARTICULAR DESULFURING THE CAST IRON BY MEANS OF SOLID MG PARTICLES AVOIDING LANCE VIBRATIONS.
